General Information About Naturalization Records

“’Naturalization’” is a voluntary process through which immigrants can become American citizens. By becoming naturalized citizens, immigrants are granted the same rights, privileges and protections as natural born citizens. Before 1790, British immigrants were considered citizens of the British colonies in America, and later American citizens. Some Protestant immigrants from other European countries requested citizenship from civil authorities. After swearing allegiance, immigrants were generally granted citizenship. The process by which other immigrants could become citizens of the British Empire or the American colonies, and later American citizens, was handled by the individual colonies then states until 1906, when the Bureau of Immigration and Naturalization standardized immigration laws and procedures. Naturalization to become a U.S. citizen was a two-part process: The Declaration of Intent to Naturalize, or First Papers, and the Naturalization Record (including the Naturalization Petition), or Final Papers. The general requirements for citizenship include residency in one U.S. state for one year and in the United States for five years The First Papers were normally filed five years before the Final Papers because of the five-year residency requirement to become a citizen.

Naturalization papers are an important source of information about an immigrant's nation of origin, his foreign and “Americanized” names, residence, and date of arrival. Naturalization records were created to process naturalizations and keep track of immigrants in the United States. Naturalization records are generally reliable, but may occasionally be subject to error or falsification. Be sure to search all possible spellings for the surname of the person for whom you are looking. Think about how the surname was pronounced, and how it sounded in the immigrant’s probable accent. The surname may be spelled differently in records that were closer to your ancestor's immigration date.

Sample Image
Immigrants could naturalize in any court that performed naturalizations. That included city, county, state and federal courts. Begin by looking for naturalization records in the courts of the county or city where the immigrant lived. Look first for the petition (second papers), because they are usually easier to find in courts near where the immigrant eventually settled. After 1906, the declaration can be filed with the petition as the immigrant was required to submit a copy when the petition the petition was submitted. Because immigrants were allowed to naturalize in any court, they often selected the most convenient court. For example, if an immigrant lived in Maine, but worked in Vermont or New Hampshire, they may have gone to a court closer to work.
