If a person lived in or near Chicago or other cities where the U.S. courts convened, naturalization records may be found in the U.S. district or circuit courts. These court records (1819–1982) are available at the [[National Archives Great Lakes Region (Chicago)|Chicago Branch of the National Archives]]. Records of the district and circuit courts in the ''Northern District'' were kept concurrently until the U.S. Circuit Court was abolished in 1911. Both courts should be checked for naturalization records. | If a person lived in or near Chicago or other cities where the U.S. courts convened, naturalization records may be found in the U.S. district or circuit courts.
