"records are people"

The USCIS Genealogy Program is a fee-for-service program providing family historians and other researchers with timely access to historical immigration and naturalization records.  Click the links at right and below to learn about our services and records.


Avoid Common Mistakes--Please read the Frequently Asked Questions (FAQs), form instructions, and other information on this website before sending any money.


The USCIS Genealogy Program offers two services:

  • Index Search: Using biographical information provided by the researcher, USCIS searches its historical immigration and naturalization record indices for citations related to a specific immigrant. Search results (record citations) are returned to the researcher, along with instructions on how to request the file(s) from USCIS or the National Archives. Fee: $20.00.
  • Record Copy Request: Researchers with valid record citations (USCIS file numbers), gained through a USCIS Genealogy Program index search or through independent research, may request copies of historical immigration and naturalization records.  Fee: $20.00/$35.00  (depending on the record type).

Records available through the USCIS Genealogy Program:

  • Naturalization Certificate Files (C-files) from September 27, 1906 to April 1, 1956
  • Alien Registration Forms from August 1, 1940 to March 31, 1944

We are currently answering requests received in mid-February 2009 or earlier.
