Typed index cards with names, dates of naturalization, court numbers, and certificate numbers of soldiers in WWI whose naturalizations were facilitated so they could serve in the U.S. Armed Forces. The Declaration of Intention requirement was typically waived to speed up the process. Many soldiers filed petitions and were naturalized in the same day. Courts were often located at military bases. Browse the index by a soldier's last name, or search by given name, surname, base name, or court number.
