Naturalization Records
The Archives is the repository for over 16,000 pages of Naturalization records ranging from approximately 1834 to 1949. In that year, all naturalization records were to be housed in St. Louis County.
Most indexed records are for a declaration of intent. In some folders there may be an additional document. For a copy of the document(s) please send $3.00 and a self-addressed stamped envelope to us at 101 South Main Street • St. Charles, Missouri 63301-2802.
