How to Fill Out Form I-9 Correctly (w/Examples & Mistakes) + FAQs

To fill out Form I-9 correctly, employees complete Section 1 by their first day of work, and employers (or authorized representatives) verify original documents and complete Section 2 within three business days of the employee’s start date.

According to a 2022 industry analysis, over 50% of audited Form I-9s contained at least one error – a costly risk for businesses. Every U.S. employer must verify each new hire’s identity and work authorization using Form I-9, making proper completion essential to avoid fines and legal issues.

Understanding Form I-9 and Why It Matters

Form I-9, officially titled Employment Eligibility Verification, is a federal form that every U.S. employer must complete for every new employee (citizen or noncitizen) hired after November 6, 1986. This requirement stems from the Immigration Reform and Control Act (IRCA), which made it illegal to hire individuals who are not authorized to work in the United States.

The Form I-9 is the core compliance tool: it documents that the employer verified the employee’s identity and employment authorization by examining acceptable documents. In simple terms, it’s how employers confirm each hire is who they claim to be and allowed to work in the U.S.

Filling out Form I-9 is mandatory for all employers, whether you run a small family business or a multinational corporation, and regardless of the employee’s citizenship status. The form itself isn’t submitted routinely to any government agency; instead, employers keep completed I-9 forms on file and must present them for inspection if Immigration and Customs Enforcement (ICE) or another authorized agency (like the Immigrant and Employee Rights Section of the DOJ or sometimes Department of Labor) asks during an audit. Because of this, an employer’s I-9 files need to be accurate and readily available. Failing to produce a properly completed Form I-9 for each employee during an audit can result in penalties.

Why does Form I-9 matter so much? Aside from the legal requirement, it helps create a paper trail that an employer did its due diligence. If an employer unknowingly hires someone unauthorized to work, a correctly filled I-9 (and a follow-up E-Verify check, if used) can demonstrate the employer’s good-faith effort to comply with the law.

Conversely, incomplete or incorrect I-9s can lead to fines even if all your employees are actually authorized – because penalties apply to procedural violations, not just hiring undocumented workers.

And if an employer knowingly hires or continues to employ an unauthorized worker, severe penalties (including heavy fines and even criminal charges for repeat offenders) can apply under federal law. In short, Form I-9 is every employer’s first line of defense against immigration-related violations and the potential hefty fines that can follow.

Critical Federal Rules for Form I-9 Compliance

To master Form I-9, you need to understand the key federal rules that govern when and how it must be completed, what documents are acceptable, and how to handle the form afterward. Here are the crucial requirements:

• Timing is everything: The employee must complete Section 1 by their first day of work for pay (ideally on or before the hire date), and the employer must complete Section 2 no later than the end of three business days after the start date. For example, if an employee starts on a Monday, Section 2 should be done by Thursday. If the employment will last less than three days (e.g. short-term day labor), then Section 2 should be completed by the first day of work. Meeting these deadlines is critical – a late I-9 is a violation even if everything else is correct.
• Use the current form: Always use the most current Form I-9 version issued by U.S. Citizenship and Immigration Services (USCIS). The form is periodically updated; using an outdated version can be considered a paperwork violation. As of late 2023, the form was streamlined to a single-page format (for Sections 1 and 2) with a separate supplement for reverifications. Employers had to transition to the new 08/01/23 edition by November 2023. Keep an eye on USCIS announcements for any new editions, especially if rules change – using the right form edition is an easy way to stay compliant.
• Original documents, not copies: The employer (or their authorized representative) must examine original, unexpired documents from the employee to complete Section 2. Photocopies, faxes, or scans cannot be accepted for I-9 purposes (with a very limited exception for certified copies of a birth certificate). The documents must be physically handled and viewed to verify security features and authenticity. (One recent exception: an August 2023 rule allows certain employers enrolled in E-Verify to examine documents remotely via live video under specific conditions – more on that later in the state nuances and E-Verify section.) In all cases, the person examining the documents must see the originals and attest on the form that the documents appeared genuine and related to the employee.
• Acceptable documents – employee’s choice: The Form I-9 comes with lists of acceptable documents divided into List A, List B, and List C. List A documents establish both identity and work authorization (for example, a U.S. Passport, a permanent resident card aka Green Card, or an Employment Authorization Document card). List B documents establish identity only (e.g. a driver’s license or state ID, school ID for students, etc.), and List C documents establish work authorization only (e.g. a Social Security card, birth certificate, or work authorization receipt). An employee can present either one List A document, or a combination of one List B and one List C document. The key is: you cannot require or specify which documents an employee should show – it’s their choice which allowable documents to provide, from the lists. Employers must not insist on a specific document (for instance, you can’t demand a green card from a permanent resident if they’d rather show their driver’s license and Social Security card – doing so is considered an unfair immigration-related employment practice). As long as the documents are on the accepted list, unexpired, and reasonably appear genuine and relate to the person, the employer should accept them.
• No over-documentation: Related to the above, don’t collect more documents than necessary. For example, if an employee shows a U.S. passport (List A), you should not record additional List B/C documents like a license or Social Security card even if they offer them – one sufficient document is enough. Similarly, don’t fill in more document entries than needed. Providing extra documents doesn’t “extra-verify” anything; it only creates potential inconsistencies. Stick to either one from List A or one from B plus one from C. (An exception: if the employee’s chosen List A document has multiple parts, like a foreign passport and I-94 work permit, you record both as a single List A entry.)
• Fill out every required field: Federal regulations require that all required fields on the I-9 be properly filled. That includes writing “N/A” (not applicable) in fields that don’t apply, rather than leaving them blank (at least under older form rules – the newest 2023 form relaxed some of the N/A requirements). For example, if an employee has no middle name or no other last names, enter “N/A” in that field. If you are not using Section 3 (reverification) on the original form, you don’t need to pre-fill N/A there; just ensure nothing that should be completed is left empty. Missing information, like a forgotten date, signature, or checkbox, is considered a technical or substantive violation depending on the field. It’s a simple but important rule: never leave required sections blank. Double-check that every line is addressed either with the correct info or an N/A.
• Retain and store properly: Employers must keep each Form I-9 on file for a specific retention period: at least three years after the date of hire, or one year after the date employment ends, whichever is later. This means you will typically keep I-9s for all current employees (no matter how long they work for you), and for former employees until the required date passes. For example, if someone worked for you for 5 years, you must keep their I-9 for the 5 years of employment plus one additional year after termination.
  • If someone worked only 2 months and you fired them, you’d keep that I-9 for 3 years from hire date (since that’s later than one year past termination in that case). It’s good practice to purge and securely dispose of I-9s that are past their retention requirement to minimize clutter – but make sure to calculate correctly so you don’t toss out a form too soon. Forms can be retained on paper, electronically, or in a hybrid manner, as long as they are accessible and reproducible for inspection on 3 days’ notice. Electronically stored I-9s must meet certain security and audit-trail standards (to ensure they haven’t been tampered with). Keep your I-9 records separate from other personnel files, ideally – this makes it easier to pull them for an audit and helps protect sensitive information.
• Present upon request: If ICE or another authorized agency serves a Notice of Inspection (NOI) for your I-9 forms, you typically have three business days to gather and present them (along with payroll records or other documents listed in the notice). There’s usually no need to proactively send I-9s to any government agency unless asked – just be prepared to produce them quickly if audited. During an audit, agents will review the forms for technical and substantive errors. Substantive violations (like missing employee signature, or missing expiration dates for work authorization, etc.) can result in fines per occurrence, while certain technical ones might be correctable. Keep in mind, even technical errors can cost you if not corrected in time. It’s wise to conduct internal self-audits periodically to catch and fix mistakes.
  • If you find an error on a form, do not backdate or white-out; rather, correct it the proper way (line through the wrong info, enter the correct info, and initial and date the correction). Never try to cover up a late or missing I-9 by backdating the form – the audit trail will usually reveal it, and the penalties (and potential criminal implications) for falsification are far worse than for a late form.
• Anti-discrimination rules: Federal law balances I-9 enforcement with employee protections. Employers should apply the same process to every new hire regardless of national origin or citizenship status. It’s illegal to use the I-9 process to discriminate – for instance, you cannot refuse to hire someone because their work authorization will expire in the future (except in the rare case where it’s a reverification issue for a current employee), nor can you treat citizens and noncitizens differently in the types of documents you require.
  • The Department of Justice’s Immigrant and Employee Rights (IER) section enforces these anti-discrimination provisions. Employers have been fined for “document abuse,” which includes demanding more or specific documents from certain workers (for example, asking only foreign-looking individuals to present a particular document or to reverify when it’s not required). The bottom line: stick to the I-9 process uniformly. Check documents for every employee, but don’t play immigration officer beyond that – if the documents appear genuine and acceptable, you should accept them and complete the form. If later a government check (like E-Verify or a Social Security no-match) flags an issue, there are protocols to follow, but during the I-9 completion, treat everyone the same.

Now that we’ve covered the foundational rules, let’s walk through how to fill out Form I-9 step by step, and then dive into examples and special situations.

Step-by-Step Guide: How to Fill Out Form I-9 (The Right Way)

Filling out Form I-9 correctly involves two main parties and sections: the employee completes Section 1, and the employer (or authorized representative) completes Section 2. There’s also a Section 3 for updates or reverifications when needed. Each section has specific requirements:

Section 1 – Employee Information and Attestation

When: Section 1 is filled by the employee no later than the first day of employment (often it’s done as part of onboarding paperwork on Day 1 or just before starting).

Who: The employee themselves must fill out and sign Section 1. The only exception is if they need a preparer or translator to assist them – in that case, the helper can fill in the info under the employee’s guidance, but there’s a special certification area for the preparer/translator to sign. Even if someone helps, the employee still must sign Section 1 to attest the information is true.

What to fill: Section 1 has several fields the employee must complete:

• Name and identity details: The employee enters their full legal name (family name/last name and given name/first name). If they have two last names or a hyphenated name, they should include both. If they have a middle initial or other middle name, that should be included; if no middle name, they can write “N/A” in that field. There’s also a field for other last names used, e.g., a maiden name or previous name. This is often overlooked – if the person had a different last name in the past (which might appear on some of their documents), they should list it here. If not, they should write “N/A” or “None” as appropriate (leaving it blank is not acceptable). These name fields are important for record-matching and ensuring the employer can tie the I-9 to the right documents.
• Address: The employee must provide their current street address, apartment number (if any; use N/A if none), city, state, and ZIP code. A P.O. Box is not acceptable here; it should be a physical residence address. This address doesn’t have to match what’s on their ID documents necessarily (for example, someone might have moved and not updated their driver’s license yet – that’s okay), but it should be their actual residence at the time of hire.
• Date of Birth: They enter their date of birth (in mm/dd/yyyy format). Accuracy here is key because it will be used if E-Verify is run and for audit checks.
• U.S. Social Security Number: There is a field for SSN. If the employer participates in E-Verify, providing the SSN is required (since E-Verify checks against the Social Security Administration database). If the employer is not using E-Verify, the SSN field is technically optional – an employee who doesn’t yet have an SSN (for instance, some newly arrived work-authorized immigrants) could leave it blank. However, it’s generally provided in most cases. If an employee has no SSN yet and you’re not E-Verify required, they can write “Applied For” (if they have indeed applied) or “N/A” depending on form instructions, but this scenario is uncommon. Most of the time, employees will have an SSN and should fill it in to help identify them in case of audit.
• Email and Telephone Number: These two fields are optional. Employees may provide their personal email address and phone number, or they can opt to write “N/A” if they prefer not to give that information. These fields are primarily used if DHS or SSA needs to contact the employee directly about a verification issue (like if an E-Verify tentative nonconfirmation arises and the employee has to be notified). While optional, it can be beneficial for employees to provide at least one way to be reached, but it’s their choice. Employers should not complete this part for the employee or pressure them to provide it.
• Immigration/Citizenship Status Attestation: This is a critical part of Section 1. The form will list checkboxes for the employee to attest whether they are:
  1. A U.S. citizen,
  2. A noncitizen national of the U.S. (this is a rare category, e.g., certain individuals born in American Samoa; most people are not in this group),
  3. A lawful permanent resident (i.e., green card holder), or
  4. An alien authorized to work until a certain expiration date.
  The employee must select one of these four options. Only one can be true for each person. Selecting the correct status is important because it guides what documents they might later present and whether reverification will be needed.
  • If the employee checks “U.S. citizen,” no additional info is needed in that part.
  • If “noncitizen national,” similarly, nothing extra (noncitizen nationals don’t have alien numbers typically; they are treated almost like citizens for work purposes).
  • If “lawful permanent resident,” the form will ask for their Alien Registration Number (A-Number) or USCIS Number. Green card holders have an A-Number (usually a 7-9 digit number) which may also be noted as a USCIS # on newer cards – it’s the same thing. The employee should enter that number to affirm their permanent resident ID.
  • If “alien authorized to work (until ____),” then the employee needs to provide:
    • an expiration date of their work authorization (from their work permit or visa status). Some work authorizations don’t have a defined end date (for instance, refugees or asylees may have “N/A” in the expiration date because their status is indefinite; the form allows them to write “N/A” in that case).
    • They also must provide either an Alien Registration/USCIS number, Form I-94 admission number, or foreign passport number with country of issuance, depending on what they have. The form has space for these. For instance, someone on an H-1B visa might put their I-94 number and passport number; someone with an Employment Authorization Document (EAD) card might just put their A-Number from the card. The employee should refer to the form instructions to know which numbers apply to them. The main point is: if they check the fourth box, they must fill in those additional fields, otherwise the form is incomplete.
• Signature and Date: After filling the above, the employee signs and dates the form in Section 1. The signature certifies that the information is true and correct and that they are indeed eligible to work in the U.S. as indicated. They should use the current date (the date they actually signed the form). If Section 1 was completed prior to the first day of work (say, at the time they accepted the job offer or during onboarding a few days early), it still must be signed no later than the first day they start work.
• Preparer/Translator Certification: If the employee used a preparer or translator to help them complete Section 1 (for example, the form is only in English except a Spanish version allowed in Puerto Rico, so if an employee isn’t fluent in English they might have someone translate it for them, or if the employee is unable to fill it out themselves due to disability or illiteracy, someone can assist), then this portion below the employee’s signature needs to be completed. The form has a checkbox for the employee to indicate whether or not they used a preparer/translator. If no preparer or translator was used, the employee must check the box that says “I did NOT use a preparer or translator.” If one or more were used, they check the other box and then the preparer/translator must provide their name, address, and sign and date the preparer section. (If more than one preparer/translator helped, the form instructions have a Supplement page to list multiple helpers.) Employers should ensure this part isn’t left blank – it’s easy for employees to skip over it, but an unchecked box here is a common mistake. The employee has to affirm one of those two options.

In summary, Section 1 is all about the employee’s personal info and legal status, and it culminates in the employee’s signed attestation that “I am aware that federal law says I can be fined or imprisoned for making false statements or using false documents on this form.” So, they are attesting that everything is truthful.

Employer’s role in Section 1: Usually, HR or the hiring manager will provide the form to the employee and maybe walk them through it if they have questions, but the employee should fill it themselves (unless a preparer does it in their presence). Once Section 1 is done, the employer should quickly review it for completeness. Make sure no required field in Section 1 is blank (check for a checked status box, a signature, a date, etc.). If something is missing, have the employee correct it right away. It’s best to catch errors immediately. Employers should also ensure the employee did not attach any documents to Section 1 – that comes later. Sometimes new hires try to be helpful by giving a copy of their license or Social Security card along with Section 1; just hold onto those for now but note that Section 1 itself should not list any documents. It’s just the employee’s declaration.

Section 2 – Employer Review and Verification

When: Section 2 must be completed by the employer (or their authorized representative) within 3 business days of the employee’s start date. For a hire that starts on Monday, the latest to complete Section 2 is end of day Thursday. If the employee presents documents on day 1 or 2, you can certainly complete it sooner. The important part is to not miss the deadline.

Who: The employer, meaning an employer’s representative (often an HR staff member, hiring manager, or other designated person) physically examines the documents and fills out Section 2. If the employee is working remotely or at a different location, the employer can appoint an Authorized Representative to act on their behalf to complete Section 2. This could be anyone the employer trusts – often a notary public, an agent at a local office, or even a colleague – there’s flexibility. The authorized rep will print and sign their name on the form, essentially stepping into the employer’s shoes. (Note: the form doesn’t require the rep to have any specific title or notary seal; a notary can perform it but they are just acting as a company’s agent, not notarizing. The employer is still liable for any mistakes the rep makes, so choose someone reliable).

What to fill: Section 2 is where the employer certifies they have seen the documents and that the person is authorized to work. Here’s what needs to be completed:

• Employee Info at top: The top of Section 2 has space for the employer to write the employee’s name exactly as it appears in Section 1 (last name, first name, middle initial) and their citizenship/immigration status number (the number corresponding to the box the employee checked in Section 1, e.g., 1 for citizen, 2 for noncitizen national, 3 for permanent resident, 4 for alien authorized to work). In the newest form edition, this top part may be simplified, but generally you ensure the form can be identified with the right person in case pages get separated.
• List A / B / C document details: This is the core of Section 2. You will fill out either the List A column or the List B and List C columns (one from each).
  • If the employee presented a List A document, enter the document title (e.g., “U.S. Passport” or “Permanent Resident Card”), the issuing authority (for a passport it’s usually “U.S. Department of State”; for a green card, “USCIS” or “DHS” is fine; for an EAD, “USCIS”), the document number, and the expiration date (if any) in the appropriate fields under List A. Some List A documents have multiple parts, for example: a foreign passport + I-94 admission record for certain visa holders, or an employment authorization card that has a document number and also may need an expiration. The form provides additional lines for multiple List A document numbers if needed. Fill these carefully, copying numbers exactly from the documents. If a document has no expiration date (uncommon, but e.g., some Permanent Resident Cards say “10-year card Expires: 02/15/2032” but the work authorization itself doesn’t expire for a permanent resident – still, put the card expiration date; or documents like a Social Security card have no expiration – but SSN card would be List C anyway).
  • If the employee presented List B and List C documents, fill out the List B section with the title (e.g., “Driver’s License” or “State ID Card”), issuing authority (like “CA DMV” for a California driver’s license, or state name), document number (e.g., license number), and expiration date. Then fill the List C section (e.g., “Social Security Card” as the title, issuing authority could be “SSA” or just leave blank if not explicitly asked – older form didn’t ask issuing authority for SS card, since it’s obviously SSA, but check the form’s fields; for birth certificate, issuing authority would be something like “State of Texas Dept. of Health”), the document number (if any, some birth certificates have numbers), and expiration date (most List C documents like SSN card or birth certificate don’t have expiration dates – in that case you write N/A in the expiration field).
  Make sure each required field in the chosen columns is filled. If using List A, leave List B and C fields marked as N/A (or the form may have you leave them blank in the new version). If using B and C, leave List A blank or N/A. One common mistake is forgetting to put N/A in unused fields if required – check the form’s instructions on how to notate unused sections.
• Additional Information field (if applicable): The I-9 has an area (sometimes on the form or in margins) for additional info. This is used for certain annotations if needed. For example, if the employee presented a receipt for a lost or stolen document, you would note “Receipt for [document] presented, expires on [date]” here. Or if the person is a student on STEM OPT extension, you’d note their Form I-20 and E-Verify info. If the hire is through certain hiring exceptions (like an employee who attests to being a minor under 18 without documents, or a person with a disability in a special program), the employer would note the exception here (e.g., “Individual under 18, ID from parent’s letter per 8 CFR …”). These situations are less common; generally, most hires won’t require anything in the additional info box. If nothing special to note, you can leave it blank. (Do not use this area to note things like “applicant seemed nervous” or any irrelevant info – stick strictly to official annotations allowed.)
• Employee’s first day of employment: Section 2 has a space to enter the date the employee began (or will begin) work for pay. This is the hire date. Sometimes, especially if you complete the I-9 on the actual start date, this is “today’s date” or a past date if you only got to Section 2 a day or two later. Ensure this date matches your company’s records (offer letter or payroll) for their start date. ICE auditors cross-check this date against payroll records. If the I-9’s “date of hire” doesn’t match the actual hire date, it’s a flag. So be precise – typically, the date of hire is the first day the person was on payroll or the actual first day they performed work. (If for some reason you did Section 2 before they actually started – which shouldn’t generally happen, but if you completed paperwork early – you’d still use the official start date in this field, not the date you completed the form.)
• Certification – signature of employer representative: Finally, the employer’s representative who reviewed the documents signs and dates Section 2, attesting that: “I certify that I examined the documents presented by the above employee, that the documents appeared genuine and to relate to the employee, and that the employee began employment on the date above.” The signer also prints their name, title, and the employer’s business name and address in the spaces provided. It’s important to fill all parts of this certification block. For example, don’t forget to include the business name and address, which is often pre-printed on electronic I-9 systems but must be written on paper forms. The address should be the location where the I-9 records are kept or the hiring site – typically your business’s main or hiring location address.

Once Section 2 is completed, the form should be reviewed for any missing info or errors. Common checks: Did we enter the document numbers correctly? Did we accidentally transpose digits? Did we sign and date it with the correct date? (Signing late or post-dating a signature is a problem – the signature date should reflect the day the employer actually signed off on the documents. If you’re doing it on the deadline day, it should be that date.) If you spot a small mistake after the fact (say you wrote the wrong expiration year), the correct way is to draw a single line through the wrong entry, write the correct info nearby, and initial/date the correction. Do not scribble out completely or use correction fluid. And never alter the form after an audit has been announced – corrections are fine in a self-audit, but once the government is involved, you have to preserve everything as is and point out any fixes separately.

What if an employee can’t produce the required documents by day 3? By law, if by the third business day the employee hasn’t provided the List A or List B and C documents (or an acceptable official receipt for a lost/damaged document), the employer cannot continue to employ that person. Essentially, you would have to suspend or terminate their employment on that basis. However, there is a grace provision for receipts: if the employee lost or had their document stolen or destroyed, they can present a receipt of having applied for a replacement (such as a receipt from the DMV for a replacement license, or from USCIS for a replacement green card) within the three days. That receipt allows them to work for up to 90 days, by which time they must show the actual replacement document and then the employer updates the I-9 with the new info. Receipts are not allowed for an initial work authorization that’s expired (except in very specific cases like automatic extensions for certain visa renewals, which are beyond the basics). So an employee can’t say “I’ve applied for a Social Security number, I’ll get it in a month” – actually, that receipt (if any) might count for List C, so that could be acceptable for SSN because it’s a new issuance, but for something like an EAD renewal, there are separate rules. In any event, the employer should document any receipt presented in the Section 2 additional info area and then remember to follow up.

In normal scenarios, by day 3 you either have completed Section 2 with proper documents or you must remove the person from active employment. This strict timeline is why it’s important to communicate with new hires from day 1 about bringing acceptable ID documents. Many employers provide a list of acceptable documents to the employee with their offer letter or onboarding packet so the person knows what to have on their first day. That can prevent delays.

Section 3 – Reverification and Rehires

Section 3 is a smaller section used only in particular situations after the initial hire is done. It can be found on the original form or on a separate Section 3 supplemental page in the newer form version. The employer will use Section 3 in these cases:

• Reverification of expiring work authorization: If an employee’s work authorization is temporary, the employer is required to reverify their eligibility on or before the expiration date of their current authorization. For example, if you hired someone who presented an Employment Authorization Document (EAD) that expires on Dec 31, 2025, you must reverify them by that date (ideally a bit before, to avoid gap). U.S. citizens and permanent residents do not need reverification when their IDs expire (e.g., don’t reverify a U.S. passport or green card expiration – those individuals have ongoing authorization by status). Reverification is for those who chose something like an EAD, I-94 with expiration, or other temporary statuses. To reverify, the employee must present a current valid document (it can be a new EAD, a renewal of their status, or any acceptable document from List A or C that shows continued authorization) and the employer fills out Section 3 with the new document details and new expiration date. The employer (or rep) then signs and dates Section 3. If the original form has no more space in Section 3 (e.g., if it was used before, or the new form uses a separate page), you can use a fresh Form I-9 Section 3 page or do a new Form I-9 altogether. Attach any new Section 3 used to the original I-9.
• Rehire within 3 years: If you rehire an employee within three years of the date of their initial I-9, you have a choice: fill out Section 3 to update their rehire date (and any name changes or document updates) or complete a new Form I-9. Many employers opt for a new I-9 to be safe, but Section 3 is perfectly acceptable if within the 3-year window. To use Section 3 for rehire, you would confirm that the original I-9 documentation is still valid. If the employee’s work authorization expired since they left, you would reverify as if they were a new hire (checking new documents). If everything is still valid (say you rehire someone who is a U.S. citizen or a permanent resident whose card is still fine), then you just note the rehire date in Section 3, update any name change if they legally changed their name, and sign/date Section 3. This essentially “reactivates” their original I-9.
• Name changes: If an employee’s legal name changes (due to marriage, divorce, etc.), employers aren’t strictly required by law to update the I-9, but it’s strongly recommended to do so for record accuracy. Section 3 has a field for name changes. You would enter the new name and then sign/date. This way, if an auditor sees the employee’s name on payroll has changed, the I-9 has a note of it too, avoiding confusion as to whether it’s the same person. (In the latest form version, name changes may simply be noted in Section 3’s supplemental sheet.)

Completing Section 3 correctly: Much like Section 2, ensure dates and signatures are done. If reverifying, use the date the new work authorization takes effect (or the date you do the reverification) as the date you sign. Always attach any new Section 3 or new I-9 to the original so they don’t get separated.

Not using Section 3: If none of the above scenarios occur, you won’t touch Section 3. If you never rehire the person or they have indefinite work authorization that never needs reverification, Section 3 will remain blank. That’s fine. Don’t put N/A in Section 3 at the time of initial completion because you might need it later; it’s only filled when applicable.

With the step-by-step process covered, you can see the flow: employee info and attestation (Section 1), employer document review (Section 2), and follow-ups if needed (Section 3). Next, let’s look at practical examples of how an I-9 is filled out in different scenarios, which will help cement the understanding.

Detailed Examples: Properly Completed Form I-9 Scenarios

Below are several common hiring scenarios and how Form I-9 should be completed in each case. These examples illustrate the types of documents presented and the entries you’d make on the form.

Scenario	Proper I-9 Completion
U.S. Citizen New Hire (Passport) – John is a U.S. citizen starting work. He has a valid U.S. passport.	Section 1: John checks the U.S. citizen box and fills out his personal info. He signs and dates Section 1 on his start date. He did not use a preparer, so he checks “no preparer used.” Section 2: The employer examines John’s U.S. Passport (List A). They record “U.S. Passport” under List A, issuing authority “Dept. of State,” the passport number, and expiration date. They leave List B and C blank (or write N/A). They enter John’s hire date (e.g., 06/01/2025) as the first day of employment. The employer signs and dates Section 2 by 06/03/2025 (within 3 days), prints their name/title, and the company name and address.
Lawful Permanent Resident (Green Card) – Maria is a lawful permanent resident. She presents her Green Card.	Section 1: Maria checks lawful permanent resident and enters her A-Number (Alien number) from the green card. She fills in her personal info (including her other last name from before marriage, since that appears on some records) and signs/date. Section 2: The employer reviews her Permanent Resident Card (Green Card), which is a List A document. They record “Permanent Resident Card” (List A), issuing authority “USCIS,” document number (her card has an A# printed as USCIS#), and expiration date of the card. (Even though permanent residency doesn’t expire, the card does every 10 years, so that expiration is recorded.) They sign and date Section 2 within 3 days, with the hire date noted and business info filled. No reverification will be needed for Maria in Section 3 because permanent residents have permanent work authorization (except in the rare case of an expiring conditional resident, but that’s another story).
Noncitizen on Work Visa (e.g., H-1B) – Arjun is hired on an H-1B visa. He presents his foreign passport and I-94.	Section 1: Arjun checks alien authorized to work until and writes the expiration date of his work authorization (for H-1B, likely the petition end date). He enters either his A-Number/USCIS# (if any) or I-94 admission number and foreign passport number in the fields. He signs and dates Section 1. Section 2: H-1B status workers typically present a Foreign Passport (List A) plus Form I-94 (which together count as a List A combination). Under List A, the employer would record “Foreign Passport” as the document title, with the country of issuance, passport number, and passport expiration date. On the next line in List A, they record “I-94 Arrival/Departure Record” with the I-94 number and expiration date (which usually matches the work authorization end date). These two documents together satisfy List A. The employer notes Arjun’s start date and completes the certification (sign, date, etc.). They know to reverify Arjun in Section 3 before his work authorization expiration (the date on the I-94) if he’s still employed then (or if he gets an extension, they’ll update it).
New Hire with List B & C Documents – Lisa is a U.S. citizen without a passport. She shows her driver’s license and Social Security card.	Section 1: Lisa checks U.S. citizen and fills out her info (including her current address and maiden name as other last name if applicable). Signs and dates. Section 2: The employer uses List B and C documents. Under List B, they enter “Driver’s License – [State]” as the title (e.g., “Driver’s License – Texas”), issuing authority (often the state or DMV, e.g., “TX Dept. of Public Safety”), the license number, and expiration date. Under List C, they enter “Social Security Card” as the document title, “SSA” or just leave authority blank (depending on form version), the SSN card’s document ID (note: Social Security cards don’t have a document number beyond the SSN itself, which is already the person’s number; older guidance says you can write “N/A” or “SSN printed on card” – most just write “N/A” for number as the card isn’t serialized), and N/A for expiration (since Social Security cards have no expiration). They then fill in Lisa’s start date and complete the certification (sign, date, etc.).
Remote Hire with Authorized Representative – Company hires Jim who will work remotely in another state. Jim can’t travel to HQ to show documents.	Section 1: Jim fills and signs Section 1 as usual on or before day 1 (this can be done via secure electronic system or printing, signing, and scanning back, etc.). Section 2: The company designates a local notary public near Jim as an Authorized Representative. Jim visits the notary (or any agent the employer chooses) with his documents. Suppose Jim presents a passport. The notary examines Jim’s U.S. Passport in person. That notary (acting as the employer’s agent) completes Section 2: writes “U.S. Passport,” etc., records the info, and signs Section 2. They will sign their name and write their title as something like “Authorized Rep.” and fill the employer’s name and address (the company’s details). The date of examination and hire date are entered. They then send the completed I-9 to the employer. The employer retains this I-9 as if they had done it. (Note: The notary’s stamp isn’t required; what’s required is their printed name/signature. The employer should provide clear instructions to the rep to ensure they fill it out correctly). This way, Jim’s I-9 is done on time. Alternative (if using E-Verify’s new remote option): If the company was enrolled in E-Verify and DHS’s alternative remote exam procedure, they could have verified Jim’s documents via a video call and copy upload by Aug 2023 rules – in that case, they’d check the “alternative procedure” box on the new I-9 and keep document copies as required.
Rehire Within 3 Years – Sara worked for the company 1 year ago and is being rehired.	The original I-9 for Sara was done 1 year ago, so it’s still on file. The employer has a choice: fill Section 3 on that I-9, or do a new I-9. Assume they use Section 3. Section 3: The employer enters Sara’s new rehire date in the appropriate field in Section 3. They also note that her name changed (she got married in the interim) by writing her new last name in the name change field. Sara is a U.S. citizen, so her work authorization never expired; no new document needed in List A/B/C fields – for a citizen, you don’t reverify. You simply re-affirm she’s authorized. The employer signs and dates Section 3. Now the I-9 is updated for the rehire. (If Sara’s original I-9 was on an older version form and they prefer, they could have just done a new form – which some prefer for simplicity).
Employee with Expiring Work Permit – Omar has a temporary work card valid until 12/31 this year.	Initial hire: Omar’s I-9 at hire was completed with his Employment Authorization Document (EAD) from List A, which had an expiration of 12/31/2025 recorded in Section 2. Reverification: As 12/31/2025 approaches, the employer reminds Omar to provide an updated document for continued work authorization. Omar gets a new EAD extending another year. The employer completes Section 3 on the original I-9 (or attaches a new Section 3 page) on 12/31/2025. In Section 3, they fill in Omar’s name, the new document (they could either list the new EAD as a List A document in the Section 3 fields or, since it’s EAD, possibly just record the document number and expiration in the margin – newer forms have fields), the new expiration date (say 12/31/2026), and they sign and date the Section 3. This updates the I-9 so Omar can continue working into the next year. If Omar did not provide a new document by 12/31/2025, the employer would have to suspend him from work on Jan 1 until he can provide valid proof.

Each scenario above shows the form being filled as required. Notice that in all cases, the employer did not dictate which documents were used – the employee chose from acceptable options. The employer’s job was to faithfully transcribe and verify those documents and ensure the form was correct.

Avoid These Common Form I-9 Mistakes

Even well-intentioned employers make mistakes on Form I-9. Here are some of the most common errors and pitfalls – and how to avoid them:

• ❌ Missing deadlines: Failing to have Section 1 completed by Day 1 or Section 2 by Day 3 is a frequent error. Avoidance tip: Incorporate I-9 completion into your new hire orientation checklist so it’s done immediately. If someone starts work remotely, make arrangements in advance for document verification by an agent or via the allowed remote procedure (if eligible). Never ignore the three-day rule – auditors will check dates on the form against hire dates.
• ❌ Incomplete or blank fields: A lot of I-9s have blanks where there should be data or “N/A.” Examples include an employee not checking a citizenship status box, leaving the “other names” field blank instead of N/A, or an employer forgetting to fill in the document title or expiration date in Section 2. Avoidance tip: Double-check each section after completion. For paper forms, use the official Form I-9 instructions (M-274 Handbook) as a guide, or use electronic I-9 software that prompts for all required fields. Train HR staff to be detail-oriented with each field. Remember that on older forms, any blank could be a violation; on newer forms, fewer N/As might be needed but it’s safer to fill something than leave a gap.
• ❌ Not signing or dating the form: Believe it or not, people often forget to sign the darn thing. Employees might forget to sign Section 1, or employers might fill Section 2 and then miss the signature or date. Without signatures, the form is essentially invalid. Avoidance tip: Make the signature line a part of your review: “Is there a signature and date in Section 1 and Section 2?” Every form, every time. If a mistake is discovered (e.g., you find an I-9 where HR forgot to sign), correct it as soon as possible – sign with the current date and, if audited, be prepared to explain. It’s better to have a late signature than none at all.
• ❌ Backdating or falsifying dates: Some employers panic when they realize they missed the deadline and backdate the form to make it look compliant. This is a big no-no. It’s falsification of a federal form, which can carry serious penalties beyond the standard fine (including potential criminal charges in egregious cases). Avoidance tip: If you missed a date, do not alter the timeline on the form. Instead, sign with the actual current date and, if possible, attach a memo explaining the circumstances. It won’t erase the violation, but it’s far better than misrepresenting the truth. The focus should be on never getting into a backdating temptation: institute reminders (some companies set tickler emails that prompt HR on day 2 or 3 if an I-9 isn’t turned in yet).
• ❌ Requesting the wrong documents (document abuse): As mentioned earlier, telling an employee exactly which documents to bring (e.g., “Bring your green card” or “You must show a U.S. birth certificate”) is illegal. Also, refusing a valid document and asking for a different one can be document abuse. For example, an employer might wrongly say, “I need to see a Social Security card and driver’s license” even though a passport was offered – that’s not allowed if the passport suffices. Avoidance tip: Provide the new hire with the entire List of Acceptable Documents (usually page 3 of the form or a printout from USCIS) and let them choose. Train whoever handles I-9s to never suggest a preference. If an employee asks, “What should I bring?” you can respond with “Any one item from List A, or one from List B and one from List C – whichever you have handy and prefer.” Consistency here is key.
• ❌ Accepting unacceptable or expired documents: Only certain documents count for I-9, and they must generally be unexpired. A common mistake is accepting an expired driver’s license or an expired passport. (During COVID, there was some flexibility on expired List B IDs due to DMV backlogs, but generally expired = no good). Another mistake is accepting a document that isn’t on the official list (e.g., a hospital birth certificate for an adult, or a taxpayer ID card – not acceptable). Avoidance tip: Use the official list and check dates. If a document has expired, politely ask the employee for a valid replacement or a different valid document. There’s a nuance: some documents, like a U.S. passport card or passport book, have expiration dates you must heed; others like a U.S. birth certificate are considered valid indefinitely (since birth certificates don’t expire). So know the difference and the list.
• ❌ Overlooking reverification duties: Employers sometimes forget to reverify employees with temporary work authorization. For instance, if you hired someone on a one-year work permit and file the I-9 away, you might not realize that a year later, you needed to update their I-9 or stop employment. Avoidance tip: Maintain a tickler system or calendar for reverification deadlines. Many companies keep a spreadsheet or use an HRIS alert for any I-9 with an expiration date in Section 1 (for aliens authorized to work) or Section 2 (if you recorded a work auth expiration). Start contacting the employee 60-90 days ahead of time to remind them to provide an updated document by the deadline. Document those reminders too. If they can’t provide by expiry, you must remove them from work to remain compliant.
• ❌ Using the wrong form version or Spanish form incorrectly: Some employers unknowingly use an outdated Form I-9 they had saved from years ago, or they download the Spanish version of the form and use it for English speakers in the U.S. (outside Puerto Rico). The Spanish form is only officially valid in Puerto Rico. Elsewhere, it can be given as a translation aid, but the employee still must complete the English form. Using the wrong version can be a substantive error. Avoidance tip: Always get the form directly from the USCIS website to ensure it’s the latest. Check the expiration date and form version in the footer. Don’t use the Spanish form for official completion unless you’re in Puerto Rico (and even then, you must be a Puerto Rico employer to store Spanish forms).
• ❌ Inconsistent practices or selective enforcement: If you only do I-9s for some people and not others, or you enforce rules selectively (like only photocopy documents for some hires), you run into both compliance and discrimination issues. Avoidance tip: Standardize your I-9 process. Every new hire, no exceptions, gets an I-9 on file. If you choose to make copies of documents (which is optional federally), do it for all employees or none – consistency is critical to avoid claims of bias. (Some states or E-Verify may compel copying certain documents, e.g., if using E-Verify and an employee presents a Permanent Resident Card or Employment Authorization, you must retain a copy. But aside from mandated cases, it’s your choice. Just be uniform.)
• ❌ Poor recordkeeping and storage: Losing I-9 forms, or keeping them in a disorganized manner, can lead to big trouble. If ICE asks for your I-9s and you can’t find some, that’s as good as not having done them. Likewise, keeping I-9s in an unsecured location could risk unauthorized access or accidental destruction. Avoidance tip: Have a dedicated I-9 file system. Many employers keep a binder or separate file (paper or digital) just for I-9s, sorted alphabetically or by year. Ensure only authorized staff can access these since they contain personal info. And when an employee terminates, mark their I-9 with the term date and eventually the destroy date (to purge later). Regularly audit your files to ensure everything is where it should be.

By being aware of these common mistakes, you can double-check your process and significantly reduce your risk. When in doubt, consult the official Handbook for Employers (M-274) which provides detailed guidance on handling tricky situations.

Key Terms and Entities in the I-9 Process

The world of Form I-9 involves several agencies, laws, and concepts. Understanding these terms will help clarify the compliance landscape and who plays what role:

Term/Entity	Description/Role
USCIS (U.S. Citizenship and Immigration Services)	The agency that creates the Form I-9. USCIS, part of the Department of Homeland Security, is responsible for the form’s design, updates, and instructions. It also administers E-Verify. USCIS provides guidance to employers through resources like I-9 Central and the M-274 Handbook.
DHS (Department of Homeland Security)	The cabinet department overseeing immigration enforcement and benefits. USCIS, ICE, and CBP all fall under DHS. When it comes to I-9s, DHS is the primary regulator. DHS sets the rules (through regulations in 8 CFR 274a), can adjust penalties, and through its sub-agencies enforces the verification laws.
ICE (Immigration and Customs Enforcement) & HSI (Homeland Security Investigations)	The enforcement arm for I-9 compliance. ICE, another DHS agency, conducts I-9 audits and investigations via HSI. They issue Notices of Inspection (audits) and can levy fines for I-9 violations. If an employer is found to knowingly employ unauthorized workers, ICE handles those cases (which can involve raids or criminal charges). Essentially, ICE “polices” the I-9s.
IRCA (Immigration Reform and Control Act of 1986)	The law that established the I-9 requirement. IRCA made it mandatory for employers to verify work eligibility and made it illegal to hire or employ unauthorized workers. It also included anti-discrimination provisions to protect workers. IRCA’s provisions are codified in the U.S. Code (8 U.S.C. §1324a for employer verification duties, §1324b for anti-discrimination).
E-Verify	An electronic verification system that complements the I-9. Run by USCIS (with SSA), E-Verify allows employers to electronically confirm the SSN and employment authorization info from an employee’s I-9 against government databases. It’s voluntary at the federal level (except for certain federal contractors and in states that mandate it). Using E-Verify doesn’t replace the I-9 – it’s a separate step after completing the Form I-9. It can catch some document or identity issues, but it also requires employers to follow specific program rules.
Authorized Representative	A person designated by the employer to act on its behalf to complete Section 2 or 3. This term comes into play especially for remote hires. An authorized rep could be a notary public, an attorney, a HR person at a different branch, or anyone the company trusts. USCIS allows this flexibility – there are no formal certifications needed. The rep basically stands in for the employer to review documents and sign the I-9. The employer is liable for any mistakes the rep makes, so training and clear instructions are important.
List A/B/C Documents	Categories of acceptable documents an employee can present for I-9 verification. List A provides both identity and work authorization (e.g., passports, green cards). List B provides identity only (e.g., driver’s license, state ID, school ID for minors) – List B documents typically must have a photo or identifying info. List C provides work authorization only (e.g., Social Security card, birth certificate, CERTAIN documents like a Native American tribal document). The I-9 forms include a detailed list; it can change slightly over time (e.g., new types of acceptable docs might be added by DHS). Employees choose from these lists.
OCAHO (Office of the Chief Administrative Hearing Officer)	The judicial entity that hears I-9 penalty cases. If an employer contests ICE’s proposed fines, the case can go before OCAHO, which is part of the DOJ. An administrative law judge reviews the case, can reduce or uphold penalties, etc. OCAHO also handles complaints of discrimination related to I-9 (brought by DOJ’s IER). Knowing this term is useful if you ever see references to cases (like “OCAHO case law on I-9 violations”).
DOJ IER (Immigrant and Employee Rights Section)	The Department of Justice unit enforcing anti-discrimination in I-9 process. IER (formerly OSC – Office of Special Counsel for Immigration-Related Unfair Employment Practices) investigates claims that an employer has engaged in unfair I-9 practices (e.g., asking only noncitizens for certain documents, or a citizen for a birth certificate but not asking others). They can levy fines and penalties too, separate from ICE. Employers have to balance being thorough on I-9s with not treating people differently based on citizenship status or origin, and IER is the watchdog for that.
Receipt Rule	Provision allowing temporary use of a receipt in place of a document. If an employee’s document was lost, stolen, or destroyed, they can present an official receipt for the replacement document. This buys them 90 days to produce the actual replacement. Examples: a receipt from the SSA for a replacement Social Security card, or a USCIS I-797 notice that they’ve applied to replace a green card. The receipt is recorded on the I-9 (with its date) and then the employer must update the I-9 with the new document info once it arrives. Receipts do not include things like application forms or printouts (must be an official agency receipt) and can’t be used for new documents that never existed (except SSN application or birth cert order, etc.). Also, receipts are not acceptable if the document is expiring (can’t use a receipt for a renewed EAD unless it’s an automatic extension scenario).
Retention Period	The length of time an employer must keep a Form I-9. As noted, this is 3 years after hire or 1 year after termination, whichever is later. For example, hire date 1/1/2025, termination 1/1/2026 -> keep until 1/1/2028 (3 years from hire is later than 1 year from term). This term comes up in instructions and audits. Employers should calculate a “destroy after” date for each I-9. Disposing early can be penalized; keeping too long isn’t penalized by law but is unnecessary and could expose extra liability.
Remote Verification (Post-2023)	The new alternative procedure for verifying I-9 documents without physical inspection. Starting Aug 1, 2023, DHS allows employers enrolled in E-Verify and in good standing to use an alternative remote examination: the employee sends copies of their documents, then shows them via live video to the employer, and the employer can check a box on the new I-9 indicating they used this procedure. Employers must keep copies of documents in this case. This is an optional alternative to in-person exam, primarily to facilitate remote hiring. It’s important to note this is only allowed if you are an E-Verify participant and follow DHS’s specific rules. It’s not simply a Facetime call casually – you have to do it in a structured way and within certain timelines.
Notice of Inspection (NOI)	Official notice from ICE that they will audit your I-9 forms. If you receive an NOI, you generally have 3 days to gather your I-9s and related documents. ICE will then review them and issue findings. An NOI is the start of a formal audit process. Knowing this term is important so that if such a notice arrives, it’s taken seriously and responded to promptly.

These terms cover the major players and concepts. Essentially, USCIS provides the form and guidance, ICE/HSI enforces compliance through audits and fines, DOJ IER enforces the anti-discrimination aspect, and E-Verify is a supplementary tool many states and employers use to bolster the I-9 process. Employers sit in the middle of these, having to navigate the rules and keep both compliance and fairness in mind.

Form I-9 vs. E-Verify: What’s the Difference and Do You Need Both?

Many employers hear about E-Verify and wonder how it relates to the Form I-9. Are they the same thing? Does doing one mean you don’t have to do the other? Let’s clarify:

Form I-9 is a mandatory paper or electronic form that every employer nationwide must complete for each new hire, as we’ve detailed above. It involves reviewing documents and attesting manually (or electronically) on a form that you have verified the person’s work eligibility. The I-9 is essentially an honor system backed by potential audits – you don’t automatically report the info to the government (except if asked during an audit).

E-Verify, on the other hand, is an internet-based system run by the government that checks the information from the I-9 against government databases (like the Social Security Administration and DHS records). When an employer participates in E-Verify, after completing an I-9, they enter the new hire’s data (name, SSN, date of birth, and document info like passport or A-number) into the E-Verify website. The system then returns a result, usually within seconds or minutes:

• Employment Authorized if everything matches up (yay, the person’s info is confirmed).
• Tentative Nonconfirmation (TNC) if something doesn’t match (maybe the name doesn’t match the SSN, or the DHS database doesn’t show work authorization). The employer must then notify the employee, who has the right to contest and get things resolved (maybe it was a clerical error, or the employee needs to update records).
• Final Nonconfirmation if after the contest period it’s determined the person is not authorized (or they chose not to contest the TNC). At that point, the employer would terminate the employment to avoid violating the law.

Key differences:

• Legal requirement: Form I-9 is federally required for all employers. E-Verify is voluntary for most employers at the federal level. However, it’s mandatory in some states or for certain federal contractors (we’ll cover state mandates shortly). If you’re not in a mandatory category, it’s your choice to enroll in E-Verify.
• Process: You must do an I-9 on paper or fillable form, even if you use E-Verify. E-Verify comes after and uses the I-9 info. Think of I-9 as Step 1 (collect documents and form) and E-Verify as an optional Step 2 (online check). E-Verify cannot be legally used on its own without an I-9, because E-Verify asks you to attest that you’ve seen the documents and completed a Form I-9.
• Purpose: The I-9 relies on the employer’s review of documents; E-Verify double-checks that those documents aren’t fraudulent (at least not obviously). For instance, I-9 might catch if a document is fake only if it looks fake, whereas E-Verify would catch if the SSN is not in SSA’s database or the name doesn’t match the number, etc.
• Outcome: A properly completed I-9 keeps you legally compliant on the paperwork side. Using E-Verify provides an extra layer of assurance. It also gives you a stronger legal defense if inadvertently employing someone unauthorized – an employer using E-Verify (and following its rules) gets a presumption that they are complying in good faith.

To illustrate the relation, here’s a quick comparison table:

Aspect	Form I-9	E-Verify
What is it?	A federally required form documenting physical verification of ID and work eligibility documents.	A voluntary (in most cases) online system to electronically verify the new hire’s work authorization against government records.
Required for…	All employers for each new hire (no exceptions by size or type of business).	Only required for certain employers (e.g., federal contractors with clause, employers in states with mandates, etc.). Optional for others who choose to enroll.
When is it done?	At hire: Section 1 by Day 1, Section 2 by Day 3 of employment. It’s completed as part of onboarding.	After the I-9 is done (usually on the hire date or within 3 days). You must enter the case no later than the third business day after the start date, similar timing to I-9.
How it works	Employer and employee fill out a form. Employer reviews original documents face-to-face. Form is kept on file, not automatically sent to government (unless audited).	Employer inputs info from the I-9 into the secure E-Verify website. The system checks databases and returns a result (Authorized / Tentative Nonconfirmation / etc.). Employer follows up if needed.
Documents needed	The actual physical documents are required to fill the form (passport, license, etc.) – no tech interface, just eyeballing docs.	Requires the same documents (since data comes from I-9), plus the employee’s Social Security number and photo if it’s a photo ID (E-Verify will prompt to compare the photo on certain docs like passport or EAD to what’s on record). If the employee presented a List B photo ID, E-Verify might also require photo matching.
Recordkeeping	Employer retains the I-9 (and any photocopies made) for required period. No routine reporting unless asked.	Employer keeps a record of E-Verify case results (you can print or save the confirmation screen or reference number). E-Verify automatically retains some info on its portal. You must close each case in the system properly.
Legal impact	An I-9 with errors can lead to paperwork fines. Not having an I-9 at all for an employee is a serious violation. I-9 is your baseline legal requirement.	Using E-Verify properly can provide a “safe harbor” that you verified to the best of your ability. However, misuse of E-Verify (like pre-screening applicants or only checking certain groups) can lead to discrimination issues. Not using E-Verify (if not required) is not a violation by itself, but if you’re required and don’t, that can lead to penalties (like state penalties or loss of contracts).
Benefits	Keeps you compliant with federal law. A well-done I-9 also helps defend if ICE audits your company.	Deters identity fraud (harder for someone to lie about SSN/name if E-Verify will catch a mismatch). Quick confirmation of work status. Some employers find it improves confidence in hires. Also, if you’re E-Verify enrolled, you now have the option for remote document verification (a new benefit as of 2023).
Challenges	It’s a manual process with lots of room for human error (hence all the mistakes we listed). Some find it confusing without training.	It adds an extra step to hiring. There can be false alarms (TNCs for legit workers due to data entry errors or name changes). It requires training staff on how to handle TNCs properly and avoid any bias. It also requires that all hires be verified – you cannot pick and choose – which means more work for HR.

The two are complementary. Think of Form I-9 as the foundation and E-Verify as an add-on that some employers use or must use.

Pros and Cons of Using E-Verify

If you have the option to use E-Verify (or are considering it), here are some major pros and cons:

Pros of E-Verify	Cons of E-Verify
Greater confidence in work eligibility: Immediately flags invalid SSNs or mismatched records, reducing risk of unknowingly hiring an unauthorized worker.	Not foolproof: E-Verify can’t catch identity theft where info is genuine but stolen (e.g., someone using a real person’s SSN who hasn’t flagged it). False negatives (TNCs) can also occur for legitimate workers due to database issues.
Legal safe harbor: Using E-Verify (and following its rules) can give a presumption of good faith compliance. It’s often looked upon favorably by ICE if you still end up with an unauthorized worker inadvertently.	Added administrative burden: Requires training staff, managing E-Verify accounts, and following specific procedures (like giving TNC notices, handling referrals). This is extra work beyond the I-9 itself.
State compliance: Satisfies state laws in places that require E-Verify, thus avoiding state penalties or business license issues.	Mandatory once enrolled: If you sign up, you must run every new hire through it (except certain exempt hires like contractors truly not employees). No skipping, which some may find rigid.
Fast results: Typically confirms an employee’s eligibility within seconds to minutes. Peace of mind early in the hire.	Potential delays for TNC resolution: If a case is a Tentative Nonconfirmation, the employee has to resolve it, which can take days or weeks with SSA/DHS. During that time, you cannot terminate based on the TNC, and it adds uncertainty.
Remote hire flexibility: (As of 2023) Allows use of the remote document verification alternative procedure, which can simplify onboarding for remote employees and reduce need for finding local reps.	Privacy and data concerns: Some critics worry about data errors in government systems or the potential for increased government monitoring of employment. These are policy debates, but worth noting as a philosophical “con” for some.
Required for some contracts: If you want to do certain federal contracts or projects in E-Verify mandated states, being enrolled is a pro/necessity to compete.	Technical issues: You rely on an online system. Outages or glitches can occasionally happen, requiring follow-up. Also, you must keep up with any E-Verify rule changes or system updates.

In summary, you need Form I-9 no matter what. E-Verify is an additional tool – sometimes mandated, sometimes voluntary – that can strengthen your compliance but also comes with responsibilities. If you operate in multiple states or plan to grow, you might eventually be required by law in one of those places to use it, so it’s good to be prepared. But if you’re a small employer in a state with no E-Verify requirement, you can decide if the benefits outweigh the effort. Many small businesses opt in because it’s free and they want that extra assurance; others skip it to avoid complexity, staying fully within the law by doing the I-9 alone.

Next, let’s delve into those state-level nuances we’ve mentioned – because while the I-9 is federal, some states add their own twist (usually via E-Verify mandates).

State-Level Nuances: How Local Laws Impact I-9 Compliance

Employment eligibility verification is a federal mandate, but over the years, states have enacted laws that can affect how employers handle the process. The most common state-level requirement relates to E-Verify. Additionally, some states have laws about cooperating with immigration enforcement or penalizing employers for verification failures. Here are the key points on state nuances:

• States Requiring E-Verify: A number of states have passed laws requiring certain employers to use E-Verify in addition to completing the I-9. In some states, all employers must use E-Verify, while in others, it’s required only for public sector employers or businesses over a certain size or those contracting with the state. For example:
  • Alabama, Arizona, Mississippi, South Carolina, Utah, Georgia (10+ employees), Tennessee (35+ employees), North Carolina (25+ employees), Florida (25+ employees) are among states that have broadly mandated E-Verify for many or all employers (thresholds in parentheses denote the minimum company size for private sector mandates as of mid-2020s). Arizona was a pioneer, requiring all employers to use E-Verify and threatening to suspend business licenses of those who knowingly hire unauthorized workers.
  • Federal contractors: Regardless of state, certain federal contracts include a clause requiring E-Verify use for the contract workforce – so if you pursue federal work, you might have to enroll.
  • Public sector & contractors: Many states like Indiana, Missouri, Nebraska, Oklahoma, Virginia, Texas, etc. require state government agencies (and often their contractors or subcontractors) to use E-Verify. So if you’re contracting with a state government, check that state’s law.
  • These laws mean that in those jurisdictions, an employer doesn’t really have a choice – failing to use E-Verify where mandated can result in state-level penalties, such as fines, debarment from contracts, or even loss of business license (like “two strikes and your business license is revoked” in extreme cases).
  • It’s crucial to stay updated because state laws change. For instance, Florida recently expanded E-Verify requirements for private employers with 25+ employees (as of 2023). If you operate in multiple states, you must comply with each applicable law.
• States Restricting Practices: On the flip side, some states (particularly those with “sanctuary” orientations) have passed laws to protect workers or limit how employers handle verification beyond federal requirements:
  • California’s Immigrant Worker Protection Act (AB 450) is a notable example. It prohibits California employers from voluntarily allowing ICE access to nonpublic areas or employee records (including I-9s) without a warrant or subpoena. It also requires employers to notify employees if an ICE I-9 audit is going to happen and to share results of the audit with employees. Additionally, California law forbids re-verifying a current employee’s work authorization at a time or in a manner not required by federal law (i.e., you can’t randomly ask an existing employee to re-prove their status if there’s no I-9 obligation to do so – that could be seen as harassment).
  • Some other states and cities have anti-discrimination ordinances that mirror or add to federal protections, ensuring employers don’t misuse the I-9 or E-Verify process to target certain groups.
  • Illinois at one point had a law requiring employers to attest that they would not misuse E-Verify and to undergo training if using it (they’ve adjusted that over time to align with federal allowances).
  • Generally, if you’re in a state like California, you need to follow both federal law and the state’s worker-protection rules. If ICE comes knocking in CA, for instance, you can’t just hand over I-9s without the proper legal process because the state says you shouldn’t unless compelled.
• Business license penalties: A few states tie immigration compliance to state licensing. For example, Arizona’s law (Legal Arizona Workers Act) can suspend or revoke state business licenses of employers who knowingly hire unauthorized workers (with E-Verify usage as a presumed safe harbor). Other states might impose fines at state level in addition to federal fines if you’re caught with violations. This patchwork means an employer might face not just ICE fines but also state consequences after an enforcement action.
• Additional document retention: Some states require longer retention of verification-related documents for public works. For example, North Carolina requires employers to keep E-Verify records of each verification for a certain period (which you’d likely do anyway). It’s not usually longer than the federal retention, but worth noting any specific local mandates.
• State audits: In a few cases, states can conduct their own audits. For instance, South Carolina’s state enforcement unit can inspect employers for compliance with its law (which might involve checking that you have E-Verify documentation or an I-9 for employees). While ICE does the federal audits, state labor departments might ask for proof of E-Verify participation in states where it’s required.

How to navigate state nuances:

1. Know your states: If you operate in multiple states or hire remote workers from various states, be aware of each state’s stance on E-Verify. For example, if your HQ is in Illinois (no mandate) but you just hired someone working from home in Alabama (which mandates E-Verify for all employers), arguably you need to comply with Alabama’s law for that employee. Generally, the conservative approach is to follow the law of the state where the work is being performed.
2. Company-wide policy: Some multi-state employers just choose to use E-Verify nationwide, even if only required in some places – to have one consistent policy. That’s fine (and builds compliance muscle memory).
3. Watch for updates: State legislatures often revisit these laws. For instance, trends show more states tightening rules (especially after seeing others do it). It’s possible new states may implement E-Verify requirements or lower the threshold for small businesses. Conversely, administrations can change, and certain requirements might relax. Always verify current law from state government websites or legal counsel for your state.
4. Don’t conflict with federal law: If a state law ever forced an employer to do something that contradicts federal I-9 rules, federal law would generally preempt it. Usually, though, states craft their laws to avoid direct conflict (like requiring E-Verify, which doesn’t conflict, or requiring notice of audits, which complements). When in doubt, seek legal advice to harmonize compliance.

In summary, while Form I-9 rules are uniform across the country, your responsibilities might not end there. Many states have effectively said, “We want to double-ensure compliance by mandating E-Verify or otherwise getting involved.” As an employer, it means you should integrate those requirements into your hiring processes. Failing to do so can mean state penalties on top of federal ones – a situation best avoided. On the other hand, states like California remind employers not to be overzealous or violate worker rights in the name of compliance. So it’s a balancing act: follow all laws, federal and state, and you’ll be in good shape.

I-9 Compliance in the Courts: Notable Cases and Legal Lessons

Over the decades since Form I-9 was introduced, there have been numerous legal challenges and cases related to employment verification. Understanding a few key rulings and cases can give insight into the importance of I-9 compliance and how the law is applied:

• Chamber of Commerce v. Whiting (2011): This was a Supreme Court case that upheld an Arizona law requiring employers to use E-Verify and allowing the state to revoke business licenses of companies that knowingly hire unauthorized workers. The U.S. Chamber of Commerce argued that Arizona’s law was preempted by federal immigration law (since immigration is primarily federal jurisdiction). However, the Supreme Court ruled that Arizona’s law fell under the state’s licensing authority (a provision in IRCA actually allows states to take licensing actions against employers hiring unauthorized workers). This case essentially gave a green light to states to mandate E-Verify and impose local consequences. Lesson: States have a role in immigration enforcement (at least via licensing), so employers can be answerable to state laws in addition to federal for verification issues.
• Arizona v. United States (2012): Another Supreme Court case involving Arizona (SB 1070 law). The Court struck down several provisions of the state law that encroached on federal immigration authority, but notably, it did not disturb the earlier E-Verify/license revocation part because that was covered in Whiting. Lesson: States cannot create their own parallel I-9 systems or criminalize the federal requirements beyond what IRCA provides (e.g., making it a state crime to work without authorization was struck down), but they can complement enforcement in certain ways.
• Kansas v. Garcia (2020): The Supreme Court here dealt with whether a state could prosecute someone for identity theft when they used someone else’s Social Security number on employment forms (including the I-9). The argument was that IRCA preempts state identity theft laws if the prosecution is based on I-9 info. The Court decided that states could prosecute individuals for identity theft, even if that same information appeared on the I-9, because the state law was of general applicability and not an employer sanction or requirement. Lesson for employers: This mainly affects employees committing fraud, but it underscores that information on the I-9 can have legal ramifications beyond just the employment verification process.
• Big I-9 Fines and Settlements: Several cases highlight what can happen to employers who fail to comply:
  • Abercrombie & Fitch (2010): The clothing retailer settled for over $1 million when ICE found that its electronic I-9 system had glitches leading to numerous errors (e.g., Section 1 incomplete). This wasn’t about hiring unauthorized workers, it was about I-9 paperwork mistakes on a large scale.
  • Pilgrim’s Pride (2017): One of the largest civil penalties for I-9 violations at the time – the poultry company agreed to a $1.5 million settlement for numerous paperwork violations discovered in an audit. They did not necessarily employ unauthorized individuals; the fine was mostly for form errors.
  • Asplundh Tree Experts (2017): This wasn’t an I-9 paperwork case but a workforce enforcement case – Asplundh had to pay a whopping $95 million ($80 million criminal forfeiture + $15 million civil) for a willful scheme to hire unauthorized workers. This shows the extreme end of knowing violations.
  • Many smaller companies have faced fines ranging from a few hundred to tens of thousands of dollars depending on the number of violations. In recent years, ICE has publicized that employers paid over $14 million in civil fines in a single year nationwide for I-9 violations. Fines per form can be over $2,500 for substantive violations, so it adds up fast.
    Lesson: Even if you never intentionally hire an unauthorized worker, sloppy I-9 practices can cost dearly. It’s often said that “paperwork violations” can bankrupt a small business if an audit finds pervasive errors.
• Discrimination Cases (DOJ IER enforcement): There have been cases where employers faced penalties not from ICE, but from the Department of Justice for misuse of the I-9 process:
  • Facebook (2021): The Department of Justice reached a settlement with Facebook for about $14 million over allegations that the company’s recruitment practices (in PERM visa processes) discriminated against U.S. workers – tangentially related to I-9 in that it’s about immigration-related employment practices.
  • Various Employers – Document Abuse: For instance, a company was fined for requiring non-U.S. citizens (but not citizens) to present extra documents or specific documents. Another company got in trouble for reverifying green card holders when not required (green cards have an expiration but permanent residents don’t need to be reverified; doing so can be considered discriminatory if you wouldn’t do it for a U.S. citizen’s expiring passport).
  • Settlements in these cases might be smaller (tens of thousands) but often require the employer to undergo monitoring and training by the DOJ.
    Lesson: Treat all employees the same in the I-9 process. You can’t, for example, require only foreign-born employees to present a birth certificate or prove something extra. Nor can you selectively E-Verify some people and not others based on how they look or their citizenship status – if you’re in E-Verify, it’s everyone. Always follow the rule: one standard procedure for all.
• OCAHO penalty adjustments: In administrative case law, we’ve seen OCAHO judges sometimes reduce penalties that ICE proposed. For example, in 2022 a case might have ICE propose say $1000 per violation and OCAHO, looking at factors (like company size, good faith, no unauthorized hires, etc.), might reduce it to $600 per violation. OCAHO decisions also clarify definitions (like what counts as a substantive violation versus technical). For instance, not having an employee’s signature is substantive (big deal), whereas a missing Zip code might be technical (you could correct it).
  Lesson: There is some due process – employers can contest fines, and sometimes it helps. But better not to be in that situation by complying upfront. Also, ICE no longer gives as much leniency on technical vs substantive as they used to; they expect you to catch and fix technical errors when given a chance.

In essence, courts have consistently reinforced the importance of the I-9 regime. They’ve upheld laws that strengthen it (like allowing states to mandate E-Verify), they’ve penalized employers who ignore it, and they’ve protected employees from being over-policed with it. As an employer or HR professional, the legal landscape tells you: take Form I-9 seriously. If you ever face an audit or investigation, having your I-9s in order will make it a non-event; if not, it could become a legal nightmare.

It’s worth noting too that immigration law is dynamic. Executive policies can shift enforcement priorities (some administrations conduct more audits, others fewer). We saw a ramp-up of I-9 audits in late 2010s, then a pause during COVID, and potentially more to come as things normalize. Additionally, proposed legislation occasionally floats the idea of making E-Verify mandatory nationwide, which would obviously change some of what’s voluntary now. So staying informed on changes is part of maintaining compliance.

Finally, let’s wrap up with a FAQ section, addressing real-world questions that employers and employees often ask about the I-9 process.

FAQs: Frequently Asked Questions about Form I-9 Compliance

Q: Do independent contractors or unpaid interns need to complete Form I-9?
A: No. Employers are not required to complete Form I-9 for bona fide independent contractors or unpaid volunteers/interns. Only individuals on payroll as employees need an I-9.

Q: Can I accept an expired document for I-9 verification?
A: No. All documents must be unexpired at the time they’re presented for I-9 purposes (with very limited exceptions like certain automatic extensions). An employee will need to provide a currently valid document.

Q: Can Form I-9 be filled out and signed electronically?
A: Yes. Employers may use electronic I-9 systems to fill, sign, and store the forms, as long as the system complies with federal requirements (ensuring the information is secure, unaltered, and auditable).

Q: Do I have to keep photocopies of the documents I review?
A: No. Copying documents for I-9 is optional under federal law (except for certain E-Verify cases or state rules). If you choose to make copies, apply the practice consistently for all employees.

Q: If an employee’s work authorization expires, do I need to reverify their I-9?
A: Yes. Employers must reverify employment authorization (using Section 3 or a new I-9) by the expiration date for any employee with temporary work authorization. U.S. citizens and permanent residents do not require reverification when their IDs expire.

Q: Can someone help an employee fill out Section 1 (like a translator or HR)?
A: Yes. An employee may use a preparer or translator to assist in completing Section 1. The preparer/translator must then complete the certification box in Section 1, and the employee still signs the form to attest it’s correct.

Q: For remote hires, do we still need an in-person document check?
A: Yes. Every new hire needs an I-9 document inspection. For remote employees, you can designate an authorized representative near the employee to inspect documents in person (or, if you’re enrolled in E-Verify, you may use the approved remote verification process with live video as per DHS’s 2023 rule).

Q: Can we complete the I-9 before the employee’s actual start date?
A: Yes. Section 1 can be completed after an offer is accepted (and before or on the first day of work). Section 2 can also be done early (after acceptance), as long as it’s no later than 3 days after the start. You cannot complete an I-9 before a job offer/acceptance (no pre-screening applicants).

Q: Can a new hire work if they haven’t provided their I-9 documents by day three?
A: No. If a new hire fails to present acceptable documents (or an official receipt for a replacement) by the end of three business days from the start date, the employer must remove them from active employment until they do.

Q: Do we ever submit the I-9 form to any government agency?
A: No. Completed Form I-9s are kept in the employer’s files. You don’t send them to the government routinely – you only show them to authorities if you are audited or asked in an official investigation.

Q: Can I store I-9 forms digitally instead of keeping paper copies?
A: Yes. You may scan and store I-9s electronically or use an electronic I-9 system. The digital storage must be secure, with regular back-ups, and you must be able to print out or transmit a legible copy to inspectors if required.

Q: Is E-Verify mandatory for all employers in the U.S.?
A: No. E-Verify is voluntary at the federal level for most employers. However, it is mandatory for certain employers, such as federal contractors with the E-Verify clause and businesses in some states that have laws requiring its use. Otherwise, it’s an optional program for added verification.
