The National Archives holds an array of important and historic records pertaining to America's past that date as far back as 1776. Also preserved at the National Archives are a variety of more recent records, such as census records, military records, maps, photographs, motion pictures, and audio and visual recordings. Specifically, the National Archives preserves records generated by the federal government that have a lasting impact on American society.

Individuals are welcome to visit the National Archives to perform research, especially genealogy, since the National Archives have a variety of important records open to the public. These include military records for the Civil War, Revolutionary War, World Wars I and II, Korean War, Panama Canal and veteran records. Certain immigration records are also preserved, including naturalization and petitions records. These are located on microfilm and separated by state, however, instead of compiled into a single database.

The naturalization records preserved by the National Archives only include records from U.S. district and federal courts, not state or local courts, who also had jurisdiction to authorize naturalizations and petitions. After 1906, federal courts received copies of all naturalization records through the INS (Immigration and Naturalization Service). Still, the state archives will have the most complete immigration records. The National Archives does offer several name indexes online that allow individuals to view the location of the microfilm reel where a particular naturalization record is. Copies of these microfilm reels can be ordered, or they can be retrieved and viewed in person.
