How to Make a FOIA or PA Request
The Freedom of Information Act (FOIA), 5 U.S.C. § 552, provides that any person has a right to request access to immigration records, except those records exemptedby the Act (e.g., classified national security, business proprietary, personal privacy, and investigative).
The Privacy Act of 1974 (PA), 5 U.S.C. § 552(a) provides legal permanent residents and U.S.citizens a right to protection of and access to records filed and retrieved by their name or personal identifier.
As required by the FOIA, ALL REQUESTS MUST BE SUBMITTED IN WRITING.  Form G-639 maybe used for this purpose, but is not required.  A link to this form can be found on this page.  A letter including the criteria below is sufficient.  Requests must be for access to existing records. The FOIA/PA Program Office will not “create” records for the purpose of a FOIA or PA request.
