Finding Naturalization & Citizenship Records USA

Naturalization is the granting of citizenship to non-American born residents. Immigrants may or may not have applied for citizenship. How do you find these records?

Before 1906 these records rarely provide an origin or parents' names. After 1906 the records are more detailed.

Sometimes applications were not completed, but the papers might have been filed. You can also look in census records, court records, passports, voting registers, homestead records and military records for proof of citizenship.

Most of the colonial oaths of allegiance have been published in Filby's Passenger & Immigration Lists Index. See more resources for immigration & Ships Passenger Lists
