Naturalization is a voluntary process by which immigrants can become American citizens and receive the rights granted with citizenship. Before 1790, British immigrants were automatically considered citizens. Some Protestant immigrants from other counties swore allegiance and requested citizenship from civil authorities. The process by which foreign immigrants could become citizens of the British empire colony, and later American citizens, was handled by the individual states until 1906, when the Bureau of Immigration and Naturalization standardized immigration laws and procedures. The general requirements for citizenship include residency in one U.S. state for one year and in the United States for five years.

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. 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 he submitted the petition. Because immigrants were allowed to naturalize in any court, they often selected the most convenient court. If they lived in the Western District but worked elsewhere, they may have gone to a court closer to work.

In 1906, the Bureau of Immigration and Naturalization was created and later renamed Immigration and Naturalization Services or INS. Some results included standardized forms throughout the country and copies of naturalization papers sent to the INS in addition to the court keeping a copy. Additional records and/or images may be added to this collection in the future.
