To request certification of nonexistence of a specific record, write directly to the USCIS Records Services Branch at the address below. It is important that all request letters contain information to specifically identify the immigrant. For example, requests must contain the immigrant’s name (including all variants and aliases), date of birth, place of birth, and as much information as possible about when and where the immigrant arrived in or lived in the United States. Names of immediate immigrant relatives can also be helpful.
In all cases the immigrant must be deceased. If the immigrant’s birth date is less than 100 years before the request date, requests for certification of non-existence must include a copy of the immigrant’s death certificate.
Requests for this service should be addressed to:
