The citizenship and naturalization records of New York State are a cornerstone for U.S. genealogical research, reflecting the state’s pivotal role as an entry point for millions of immigrants. Prior to 1906, naturalizations occurred in a multitude of courts—federal, state, county, and even local—especially in New York City. Records from this period vary in format but often include declarations of intention, petitions, and final orders. After 1906, US federal court records (Southern and Eastern Districts of New York) provided standardized forms with richer personal and family details. Passport applications, frequently filed by New York residents, add further genealogical value. These records document the journeys of Irish, Italian, Jewish, German, and countless other immigrants who shaped New York’s—and America’s—story.
