Massachusetts, one of America’s earliest and most historically significant states, offers a rich trove of citizenship and naturalization records. Local courts handled naturalizations before 1906, with early records from municipal, police, and superior courts—especially in cities like Boston. These documents vary but often include declarations, petitions, and final papers. After 1906, standardized federal court records (primarily from Boston’s U.S. District Court) offer more detailed data, including photographs and family information. Massachusetts was a magnet for Irish, Italian, Portuguese, Jewish, and Eastern European immigrants, whose citizenship journeys are documented in these records. Passport applications provide additional genealogical details. Together, these sources reveal the personal narratives behind Massachusetts’ dynamic immigrant heritage.
