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. Individual States handled naturalization until 1906 when the Bureau of Immigration and Naturalization standardized immigration laws and procedures.

Naturalization to become a U.S. citizen is 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 naturalization 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. Immigrants or their families often changed or Americanized the spelling and pronunciation of their names especially their surname, thus the surname may be spelled differently in records that were closer to your ancestor's immigration date. Also, 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.
