History
Naturalization is the process of granting citizenship to foreign-born residents. Naturalization papers are an important source of information about an immigrant’s place of origin, his foreign and Americanized names, residence, and date of arrival.

Immigrants to the United States have never been required to apply for citizenship. Of those who applied, many did not complete the requirements for citizenship. Evidence that an immigrant completed citizenship requirements can be found in censuses, court minutes, homestead records, passports, voting registers, and military papers. Even if an immigrant ancestor did not complete the process and become a citizen, he may have filed a declaration. These declarations can be very helpful.

Records
Various types of records were created during the naturalization process, including declarations of intention, petitions for naturalization, oaths of allegiance and certificates of naturalization and citizenship. Each record can give details about a person, such as age, residence, country or city of origin, ethnic background, the date and port of arrival, the name of the ship, names of spouse and children with their birth dates and places, and previous residences or current address.

Records for earlier years usually contain less information than those after 1906, when the federal court system for naturalization was revised and details such as birth date and place, physical description, and marital status may be given.

Naturalization records have been filed in the district courts of the District of Columbia and the federal courts.
