USCIS (United States Citizenship and Immigration Services) is the US government agency that holds naturalization records and issues 'no record' letters for CBD cases.
In depth
USCIS (United States Citizenship and Immigration Services) is the US government agency responsible for immigration and citizenship services. It holds naturalization records for US naturalizations after 1906 and issues 'no record' letters (via the USCIS Index Search) for CBD cases.
For CBD cases involving ancestors who emigrated to the United States, the USCIS Index Search is the standard first step. The search costs $65 and takes 4-6 months. If no naturalization record is found, USCIS issues a 'no record' letter. If a record is found, USCIS provides a certified copy.
USCIS also holds other records relevant to CBD cases: Alien Files (A-Files), visa files, registry files, and naturalization certificates. These can be requested through the USCIS Genealogy Program.
