Which single documents prove both identity and work authorization for a new job?

List A documents on Form I-9 are the ones that prove both your identity and your authorization to work in the United States by themselves. A US passport and a Permanent Resident Card are two common examples listed by US Citizenship and Immigration Services.

What makes a document List A

USCIS organizes acceptable Form I-9 documents into three lists, and it defines List A specifically as documents that establish both identity and employment authorization in a single document, rather than needing a separate pairing. A US Passport or US Passport Card is given as a direct example of a List A document on the official acceptable documents page, and a Permanent Resident Card is listed there as a second example.

Why that matters when you are hired

Employers must complete Form I-9 for every person they hire in the United States, and both the new hire and the employer have parts of the form to fill out. Presenting one valid List A document satisfies the identity and work authorization requirement on its own, without needing a second document from another list.

Federal law requires every employer who hires someone for work in the United States to complete this form, which covers home health agencies the same way it covers any other employer.
