How Do I Prove Legal Authorization to Work in the United States?

To legally work in the United States, employees must demonstrate their eligibility by presenting specific documents approved by the Department of Homeland Security (DHS). These documents fall under List A or List C, as outlined in federal guidelines. Employers use these documents to complete the mandatory Form I-9, which verifies both identity and employment authorization. Here's everything you need to know.


What Are Acceptable Documents for Work Authorization?

The documents required to prove legal work authorization fall into the following categories:

  • List A: Documents that establish both identity and employment authorization.
    Examples include:

    • U.S. Passport or U.S. Passport Card

    • Permanent Resident Card or Alien Registration Receipt Card (Form I-551)

    • Employment Authorization Document (EAD) with a photograph

  • List C: Documents that establish employment authorization only.
    Examples include:

    • Social Security Card (unless it is marked “Not Valid for Employment”)

    • Original or certified copy of a birth certificate issued by a state, county, or municipal authority

    • Form I-94 or I-94A indicating work-authorized status


Why Is This Important?

Employers are required by law to verify the identity and employment authorization of every person they hire. Form I-9 is a critical part of this process and ensures that all employees are legally eligible to work in the U.S. Failure to provide the correct documentation can delay or prevent your ability to start employment.


How to Prepare Your Documents

  1. Ensure Documents Are Valid: All documents must be unexpired and in good condition.

  2. Present Originals: Employers cannot accept photocopies. You must provide the original document(s).

  3. Confirm Eligibility: Check the specific requirements for your situation to ensure you have the appropriate document(s).
