Citizenship, Passport and Naturalization
Naturalization records can be rich in detail, providing the date of immigration and the ship, names, ages, and addresses of family members, birth information, current and past residences, signatures, and affidavits from witnesses.
Many immigrants, anxious to become citizens, began the citizenship process by taking out papers in the county where they first arrived in the United States.
