Naturalization Records
Introduction and Links to Resources
Naturalization is the process by which an alien becomes an American citizen. These records can provide a researcher with information such as a person's birth date and location, occupation, immigration year, marital status and spouse information, witnesses' names and addresses, and more.

Where can I find Naturalization Records?
Pre-1906:
Prior to 1906, any "court of record" (municipal, county, state, or Federal) could
grant U.S. citizenship.
As a general rule, the National Archives does not have naturalization records
created in State or local courts. However, a few indexes and records
have been donated to the
National Archives from counties, states and local courts and are available as
National Archives microfilm publications.
See the list of this county and state microfilm available.
For pre-1906 naturalizations:
- Contact the State Archives for the state where the naturalization occurred to request a search of state, county, and local courts records.
- Contact the NARA regional facility that serves the state where naturalization occurred to request a search of Federal court records
Naturalizations After 1906:
After 1906, the courts forwarded copies of naturalizations to the Immigration and
Naturalization Service (INS).
- Naturalizations from Federal Courts are held in the NARA's regional facilities for the Federal courts for their area.
-
The National Archives in Washington, D.C. holds naturalization records
for Federal Courts in Washington, D.C.
