what are i9 documents

Form I-9 is a document used by employers in the United States to verify the identity and employment authorization of individuals hired for employment in the country. Employees must provide documentation to their employers to show their identity and authorization to work. The documents that are acceptable for this purpose are listed on the last page of the Form I-9. The list includes documents that establish both identity and employment authorization, documents that establish only identity, and documents that establish only authorization to work. Examples of acceptable documents include a U.S. passport, a Permanent Resident Card, a foreign passport with Form I-94, and an Employment Authorization Document issued by the Department of Homeland Security.
