What Documents Does an Employer Need to Complete Form I-9 Verification?

Number Name Description
1 U.S. Passport or U.S. Passport Card Employers must accept a U.S. Passport or U.S. Passport Card as valid List A documents to establish both identity and employment authorization when completing Form I-9. These documents prove U.S. citizenship and satisfy the verification requirements without needing additional documentation.
2 Permanent Resident Card (Form I-551) Employers must verify Form I-9 eligibility using the Permanent Resident Card (Form I-551) as a primary document, which proves an employee's lawful permanent resident status in the United States. This card contains critical information including the employee's name, photograph, alien registration number, and expiration date, all essential for accurate identity and employment authorization verification.
3 Employment Authorization Document (EAD, Form I-766) Employers must review the Employment Authorization Document (EAD, Form I-766) to verify an employee's identity and work authorization during Form I-9 verification, ensuring the document is unexpired and corresponds to the employee. This document serves as both proof of identity and employment eligibility under U.S. immigration law, making it critical for compliance with I-9 requirements.
4 Foreign passport with Form I-94 or Form I-94A Employers must verify an employee's identity and employment authorization by reviewing a foreign passport accompanied by Form I-94 or Form I-94A, which provides evidence of legal admission into the U.S. The Form I-94 or I-94A must indicate a valid nonimmigrant status and employment authorization corresponding to the employee's visa category.
5 Driver's License An employer needs a valid driver's license as one of the acceptable identity documents to complete Form I-9 verification, confirming the employee's identity and work authorization in the United States. The driver's license must be state-issued and contain a photograph or identifying information such as name, date of birth, gender, height, eye color, and address to satisfy the document requirements under List B of Form I-9.
6 State ID Card Employers must verify an employee's identity and employment authorization using acceptable documents listed on the Form I-9, including a State ID Card from the employee's state of residence. The State ID Card serves as a valid List B document confirming identity, but employers must also examine an additional List A or List C document to establish employment eligibility.
7 School ID Card with Photograph Employers must accept a School ID Card with Photograph as a List A document to establish both identity and employment authorization when completing Form I-9, provided it meets the criteria outlined by the U.S. Citizenship and Immigration Services (USCIS). This document verifies the employee's identity through the photo and is used alongside other acceptable documents if it does not solely establish work authorization.
8 Voter Registration Card Employers must review and verify documents listed on the Form I-9's Lists of Acceptable Documents to complete employee verification, with the Voter Registration Card not qualifying as an acceptable document for identity or employment authorization. Acceptable documents include a U.S. passport, Permanent Resident Card, or state-issued driver's license combined with a Social Security card, ensuring compliance with USCIS requirements.
9 U.S. Military Card or Draft Record An employer must collect a U.S. Military Card or Draft Record as List A documentation to verify both identity and employment authorization when completing Form I-9.

These documents are critical for verifying employment eligibility for individuals affiliated with federally recognized tribes under U.S. immigration law.
13 Birth Certificate (Original or Certified Copy) Employers must verify an employee's identity and employment authorization by reviewing original or certified copies of documents listed on the Form I-9, including a birth certificate that is either original or a certified copy issued by a government authority. A valid birth certificate must contain the employee's full name, date of birth, place of birth, and the signature or official seal of the issuing agency to satisfy Form I-9 requirements.
14 Social Security Card Employers must verify an employee's identity and employment authorization by completing Form I-9, which includes reviewing documents such as a Social Security Card that proves the employee's authorization to work in the United States. While the Social Security Card alone serves as acceptable proof of employment authorization, it must be presented alongside a valid photo identification document to fulfill federal verification requirements.
15 Certification of Birth Abroad (Form FS-545, Form DS-1350, or Form FS-240) Employers completing Form I-9 verification must accept the Certification of Birth Abroad documents, including Form FS-545, Form DS-1350, or Form FS-240, as valid proof of identity and employment authorization.

Employers must ensure the EAD is unexpired and includes a photograph, name, and other identifying information matching the employee's details on Form I-9 to comply with federal verification requirements.
19 School Record or Report Card (for minors) Employers must accept a school record or report card as List C documents to verify employment authorization for minors completing Form I-9. These documents establish identity without providing evidence of work eligibility, requiring a corresponding document from List A or List B to satisfy verification requirements.
20 Clinic, Doctor, or Hospital Record (for minors) Employers must obtain a Clinic, Doctor, or Hospital Record as acceptable List C documents to verify the identity and employment authorization of minors when completing Form I-9. This medical record must include the minor's name and a recent date of medical examination to satisfy Form I-9 requirements for minors lacking standard identity documents.
