Iowa Naturalization and Citizenship

United States &gt; U.S. Naturalizations &gt; Iowa &gt; Naturalizations

History
Naturalization proceedings in Iowa are handled primarily by district courts. These records include declarations of intention, petitions for naturalization, and certificates of naturalization and citizenship. Naturalization records may give a person's age, country or city of origin, date of arrival, port of arrival, and names of witnesses. After September 1906, the records may also give birth date and birthplace, names of spouse and children (with their birth dates and birthplaces), and name of the ship. Naturalization papers may be included with homestead land applications.
