Kansas Naturalization and Citizenship
Naturalization records up to 1906 have been kept in the Topeka Office of the U.S. Circuit Court and by the clerk of the district court of each county in Kansas. Some records from the Topeka Circuit Court were transferred to the National Archives—Central Plains Region in Kansas City, Missouri. This office also has U.S. District Court records from 1916 to 1966. The Family History Library has acquired some copies of naturalization records under the county, and records from the District court under the state.
In 1906 the Immigration and Naturalization Service (now United States Citizenship and Immigration Services) was created, forms were standardized, and duplicate copies of naturalization records were sent by the court to the INS. To access these records, download a FOIA (Freedom of Information Act) form from www.uscis.gov, fill is out and send it to the address listed on the form. You may also contact the National Archives—Central Plains Region at http://www.archives.gov/central-plains/kansas-city/ for naturalization records.
