In depth
A 'no record' letter (also called a 'certificate of no record' or 'negative search result') is an official document certifying that a search of naturalization records found no evidence that the person naturalized. It is used in CBD cases to prove that the citizenship chain was not broken by naturalization.
For CBD cases involving ancestors who emigrated to the United States, the USCIS Index Search produces a 'no record' letter if the search finds no naturalization records. This is the standard proof that the ancestor never naturalized as a US citizen.
Equivalent 'no record' letters can be obtained from: NARA (National Archives), county courts, the UK Home Office, Library and Archives Canada, the Australian National Archives, and equivalent authorities in other countries.
