An alien file, commonly known as an A-file, is the collection of documents that the Department of Homeland Security (DHS) maintains for non-citizens. It typically contains all of the official files related to immigration status, citizenship, or relief, and includes both documents submitted by the non-citizen as well as any investigations, statements, correspondence, and memoranda created by the agencies. It also may include other identifying documents, such as birth certificates.
Did you know that you can request a copy of your A-file? U.S. citizens and permanent residents may also request copies of records from other people's A-files (provided the person consents).
Make a request for these immigration files by filing Form G-639, Freedom of Information/Privacy Act Request. Learn more.
