Form I‑9 (Employment Eligibility Verification): What It Is and How To Handle It

Form I‑9 is not an IRS tax form, and it is not filed with the IRS. It is an immigration and employment form from U.S. Citizenship and Immigration Services (USCIS) that employers must use to verify a new hire’s identity and authorization to work in the United States. You fill it out when you start a job, and your employer keeps it in their records; it normally never goes to a government office unless there’s an audit.

Quick summary: Form I‑9 in real life

• Purpose: Prove to your employer that you’re legally allowed to work in the U.S.
• Agency involved:USCIS (part of the Department of Homeland Security), and sometimes Immigration and Customs Enforcement (ICE) for audits.
• Who completes it: Both you (Section 1) and your employer (Section 2, sometimes 3).
• Where it goes: Stays with the employer’s HR or payroll records, not mailed to IRS or USCIS in routine cases.
• Main action you can take today:Gather acceptable identity and work authorization documents and confirm with your employer how and when they will review the originals.
• Real friction point: Showing original documents (not photocopies) in person or via an approved remote process by the strict deadline.

What Form I‑9 Actually Does (and Doesn’t Do)

Form I‑9 is used to confirm two things: who you are (identity) and that you’re allowed to work in the U.S. (employment authorization). Your employer is legally required to have a completed I‑9 for almost every paid employee hired after November 6, 1986.

This form is not a tax form, even though it often gets handed out with W‑4 and other payroll forms, and it is never used to calculate your taxes or benefits. It is also not an application for immigration status; instead, it relies on documents you already have (like a green card or Employment Authorization Document) to show your current status.

Key terms to know:

• USCIS (U.S. Citizenship and Immigration Services) — Federal agency that designs and controls Form I‑9 and many immigration forms.
• ICE (Immigration and Customs Enforcement) — Federal agency that can inspect employers’ I‑9s and issue fines or penalties.
• List A / List B / List C documents — USCIS categories of documents you can show your employer to prove identity and work authorization.
• Reverification — When an employer must update I‑9 information because your work authorization has an expiration date.

Rules and acceptable documents sometimes change or are interpreted differently based on your location and individual situation, so it’s wise to confirm details with official resources or a qualified advisor.

Where I‑9 Connects to the Official System

In normal hiring, you interact only with your employer about Form I‑9, but in the background the official system is:

• USCIS: Publishes the current Form I‑9, instructions, and the official list of acceptable documents, and runs the optional E‑Verify system many employers use to check your information electronically.
• ICE: May conduct I‑9 audits and inspections of employers; if your employer is audited, they must show the I‑9s they’ve kept for each employee.

You do not send Form I‑9 directly to USCIS or ICE yourself. Instead, your employer’s HR or onboarding office is the official touchpoint for you. For questions about how to complete the form:

• You can ask your employer’s HR/payroll department for the official I‑9 instructions.
• You can call the USCIS Contact Center using the phone number listed on the official USCIS.gov site and ask general questions about acceptable documents or how the form is supposed to be completed.

To avoid scams, only trust websites and contact numbers ending in “.gov” when you’re looking up information about I‑9 rules or immigration documents.

What You Need to Prepare for Form I‑9

For most people, the main work involved with I‑9 is getting the right documents together on time and making sure they are original, unexpired, and in your name that matches the form.

Documents you’ll typically need:

• Valid U.S. passport or U.S. passport card (this alone satisfies both identity and work authorization as a List A document).
• Or a state driver’s license or state‑issued ID card (List B, identity) plus a Social Security card that is not labeled “Not valid for employment” (List C, work authorization).
• For non‑citizens, documents such as a Permanent Resident Card (green card) or Employment Authorization Document (EAD) are commonly used (List A).

You only need to provide one document from List A, or one from List B plus one from List C; you do not need to show everything you have. The employer must review the actual original document, not a photo or photocopy, unless there is a temporary USCIS policy allowing specific remote verification procedures and your employer uses them.

If you don’t have typical documents handy (for example, you lost your Social Security card), some alternative documents are allowed (like a birth certificate for List C, or certain school IDs for List B for younger workers), but you need to check the current official list of acceptable I‑9 documents through the USCIS site or your employer’s HR office.

Step‑by‑Step: Completing Form I‑9 With Your Employer

1. Confirm how your employer handles I‑9

Ask your hiring manager or HR contact when and where you’ll complete Form I‑9 and show your documents. Many employers include I‑9 in their onboarding system or give you a paper copy and a deadline (typically by your first day or within three business days of starting work).

What to expect next: They will either send you a link to an online onboarding portal or give you a paper Form I‑9 along with instructions about which HR person will check your documents.

2. Fill out Section 1 (your part)

Before or on your first day of work, you must complete Section 1. You’ll provide:

• Your full legal name, address, date of birth, and contact information.
• Your citizenship or immigration status (U.S. citizen, noncitizen national, lawful permanent resident, or noncitizen authorized to work).
• For certain statuses, extra information such as Alien Registration Number (A‑Number), USCIS Number, or Form I‑94 number.

You must then sign and date the form, confirming the truth of what you entered. If someone helps you fill out the form (because of language or disability), they must also complete the Preparer/Translator section.

What to expect next: HR or your manager will tell you when to bring or show your original documents so they can fill out Section 2.

3. Gather and bring acceptable documents

As soon as you know your start date, take one concrete action today: identify which acceptable documents you will use and put them in a safe place, ready to bring to HR. If your documents are in another city or with a family member, arrange to get them as early as possible.

Bring your originals (not photocopies) to the place your employer tells you, or, if the employer is allowed to use remote verification, follow their instructions for showing documents via approved video or authorized representative.

What to expect next: The employer’s representative will review your documents, record the document titles, numbers, and expiration dates in Section 2, and sign to confirm they saw the originals.

4. Let the employer complete and store the I‑9

Once your documents are verified, the employer:

1. Completes Section 2 with document details.
2. Signs and dates Section 2.
3. Keeps the I‑9 in their own records for a set period (typically three years after hire or one year after employment ends, whichever is later).

If your work authorization has an expiration date, the employer must track it and may later complete Section 3 to reverify your eligibility after you present updated documents.

What to expect next: You normally will not hear anything further about the I‑9 unless there is a problem with your documents, your employer uses E‑Verify and gets a tentative nonconfirmation, or your authorization is close to expiring.

5. If your status or documents change

If you are a non‑citizen with time‑limited work authorization, put a reminder in your calendar several months before it expires to renew your underlying immigration document (such as your EAD) through the appropriate USCIS process. After you receive the new document, you’ll typically need to show it to your employer so they can update Section 3 or a new I‑9, depending on their procedures.

What to expect next: HR will update the form and may ask you to sign where needed; you do not re‑file anything with USCIS through the I‑9 itself.

Real‑world friction to watch for

Real‑world friction to watch for
A very common snag is that workers bring photocopies or expired IDs to the I‑9 meeting, and the employer legally cannot accept them; this often delays the start date or forces extra trips to HR. To avoid this, compare your documents against the current USCIS list of acceptable documents, double‑check expiration dates, and physically set aside the originals (passport, green card, EAD, or ID + Social Security card) before your first workday.

Getting Help and Staying Safe from Scams

If you are unsure what documents you can use or how to answer the status question in Section 1, you have a few legitimate options:

• Employer’s HR or onboarding office: Ask something like, “Can you confirm which documents you can accept for my I‑9 so I can bring the right originals?” They can’t give you immigration legal advice, but they can show you the official list of acceptable documents.
• Immigration legal aid or accredited nonprofit: Search for a local legal aid office or immigration services nonprofit and ask if they provide brief consultations on work authorization and I‑9 document choices.
• USCIS official resources: Search for “Form I‑9 USCIS instructions” on a .gov site and review the most recent version to see the exact document lists and special rules.

Because I‑9 involves your identity documents and immigration status, be cautious about anyone online who offers to “fix your I‑9” or “sell you documents” for a fee. Do not email or text photos of your passport, green card, or Social Security card to unverified people, and only share these with your actual employer through the process they describe.

You cannot complete or store your official Form I‑9 through HowToGetAssistance.org or similar informational sites; the real process must go through your employer using the current official form from USCIS. Once you’ve confirmed your documents and your meeting or submission method with HR, you’re in position to complete your I‑9 properly and move forward with your job.
