The USCIS Genealogy Program is authorized to make five series of the agency’s historical records available to requesters. Other agency records may be available from the USCIS Freedom of Information (FOIA) Program, or may have transferred to the National Archives.
Requests are accepted online as well as through the mail. Please read our “Records Frequently Asked Questions” and “Common Errors” section before submitting a request. Answers can also be found in our “Help” section.
