I-9 Employment Identity Verification: Acceptable Documents, Common Employer Errors, and 2026 Compliance Updates
Under the Immigration Reform and Control Act of 1986 (IRCA, 8 U.S.C. § 1324a), all employers in the United States must verify the identity and employment authorization of every newly hired employee. Administered by U.S. Citizenship and Immigration Services (USCIS) and enforced through workplace audits by Immigration and Customs Enforcement (ICE), Form I-9 compliance requires strict adherence to statutory document lists, completion timelines, and recordkeeping standards to avoid substantial civil penalties.
Statutory Framework: Section 1, Section 2, and Document Lists
Form I-9 compliance is governed by strict chronological deadlines that employers and new hires must follow without exception:
- Section 1 (Employee Attestation): The employee must complete and sign Section 1 no later than the first day of employment for pay, providing their legal name, address, date of birth, and attesting under penalty of perjury to their citizenship or immigration status.
- Section 2 (Employer Review and Verification): The employer must physically examine original, unexpired documentation presented by the employee and complete Section 2 within three business days of the employee's first day of work for pay.
- Section 3 (Reverification): Employers must reverify employees whose temporary employment authorization expires before the date noted on their documentation. Reverification must never be conducted on U.S. citizens or lawful permanent residents presenting Form I-551 cards.
Employees choose which documents to present from the official Form I-9 Lists of Acceptable Documents. Documentation falls into three statutory categories: List A documents (such as a U.S. Passport, Form I-551 Permanent Resident Card, or Form I-766 Employment Authorization Document) establish both identity and employment eligibility. List B documents (such as a state driver's license or state ID card with photo) establish identity only, and must be paired with a List C document (such as an unrestricted Social Security card or certified state birth certificate) establishing work authorization.
Form I-9 Acceptable Document Categories and Verification Rules
The following table outlines standard acceptable documents under USCIS guidelines, indicating what each document establishes and mandatory employer verification checks.
| Document Category | Acceptable Document Examples | Eligibility Established | Employer Verification Requirements |
|---|---|---|---|
| List A (Identity & Work Eligibility) |
U.S. Passport, Form I-551 (Green Card), Form I-766 (EAD Card) | Establishes both identity and legal employment authorization | Examine original document; confirm document appears genuine and relates to employee; record title, issuing authority, document number, and expiration date. |
| List B (Identity Only) |
State Driver's License, State ID Card, School ID with photo | Establishes identity only; must be combined with a List C document | Check photograph, expiration date, issuing state; ensure name matches Section 1; verify document has not expired. |
| List C (Work Eligibility Only) |
Unrestricted Social Security Card, Form FS-240, Certified Birth Certificate | Establishes employment authorization only; must be combined with List B | Ensure Social Security card does not bear restrictive employment wording; verify official issuing seal on birth certificates. |
| Receipts (Temporary) | Receipt for replacement of lost, stolen, or damaged acceptable document | Temporary proof of application; valid for 90 days from hire date | Employee must present actual replacement document within 90 days; receipts are invalid for employment lasting under 3 days. |
Common Employer Errors, Remote Rules, and Civil Penalties
Workplace inspections by ICE and audits by the Immigrant and Employee Rights Section (IER) of the Department of Justice frequently identify substantive and procedural violations that generate severe financial liabilities.
Frequent compliance errors include:
- Accepting Expired Documents: Except for specific automatic extensions announced by USCIS for certain nonimmigrant categories, all documents presented for Form I-9 must be unexpired at the time of inspection.
- Over-Documentation and Document Abuse: Requiring an employee who presents a valid U.S. Passport (List A) to also provide a Social Security card (List C) violates anti-discrimination provisions under 8 U.S.C. § 1324b.
- Failing the Three-Day Timeline: Executing Section 2 after the three-business-day window constitutes a substantive paperwork violation subject to mandatory statutory fines.
- Improper Remote Verification: Employers must perform in-person physical examination unless enrolled in E-Verify in good standing and utilizing the permanent USCIS Alternative Procedure, which requires live video interaction and digital copy retention.
Employers must retain completed Form I-9 records for three years after the date of hire or one year after employment ends, whichever is later. Civil monetary penalties for substantive paperwork errors range from hundreds of dollars to thousands of dollars per form, while knowingly hiring or continuing to employ unauthorized workers carries escalating fines exceeding twenty thousand dollars per unauthorized individual for repeat violations.
Frequently Asked Questions
Can an employee use a driver's license alone for I-9 verification?
No. A state driver's license is a List B document that establishes identity only. To satisfy Form I-9 statutory requirements, an employee presenting a driver's license must also present an acceptable List C document that establishes employment authorization, such as an unrestricted Social Security card or a certified state birth certificate.
What documents are in List A for I-9?
List A documents establish both identity and employment authorization. Primary examples include a valid U.S. Passport or U.S. Passport Card, Form I-551 (Permanent Resident Card), Form I-766 (Employment Authorization Document), a foreign passport with an unexpired temporary I-551 stamp, and a foreign passport with Form I-94 indicating nonimmigrant work authorization.
How long must employers retain I-9 forms?
Employers must retain completed Form I-9 records for three years from the employee's date of hire or one year from the date employment is terminated, whichever date is later. Forms can be stored on paper, on microfilm/microfiche, or in an electronic format meeting USCIS security and audit trail standards.
What are the penalties for I-9 violations?
Civil penalties enforced by ICE depend on the severity of the violation and prior employer history. Substantive paperwork errors incur fines ranging from several hundred to thousands of dollars per form. Knowingly employing unauthorized workers incurs penalties ranging from thousands to over twenty thousand dollars per individual for repeat offenses, along with potential debarment from federal contracting.
Does E-Verify replace the I-9 form?
No. E-Verify is an electronic employment eligibility confirmation system operated by the Department of Homeland Security (DHS) and the Social Security Administration (SSA). It supplements, but does not replace, the mandatory Form I-9 process. Employers must complete Form I-9 before initiating an E-Verify query.
Executing accurate Form I-9 verifications is an essential legal obligation for every employer operating in the United States. By maintaining standardized document review procedures, adhering strictly to the three-business-day timeline, avoiding over-documentation, and properly utilizing USCIS remote inspection protocols when enrolled in E-Verify, businesses ensure federal compliance and protect workplace integrity.
