United States, Index to Naturalizations of World War I Soldiers - FamilySearch Historical Records

United States

What is in This Collection?
Card index to naturalizations of soldiers of foreign birth during World War I. The index is from National Archives publication M1952 Index to Naturalizations of World War I Soldiers, 1918, part of Record Group 85 Records of the Immigration and Naturalization Service. "Aliens serving in the U.S. military did not gain citizenship through service alone. The naturalization of soldiers was performed under certain provisions of nationality law facilitating the naturalization of members of the U.S. armed forces. These provisions waived the Declaration of Intention requirement and waived or reduced the residency requirement. Thus many soldiers filed petitions and were naturalized the same day. The expedited naturalization of soldiers could have been performed at either a Federal, State or local court having jurisdiction over the soldier's military base, or a judge from any of those courts might have held "naturalization court" at the military base. In either case, one copy of the petition should be on file in the court's records. Another copy was filed with the Immigration and Naturalization Service (INS) which holds duplicate copies of all naturalizations granted after September 26, 1906." -- Introduction: National Archives Publication M1952 Index to Naturalizations of World War I Soldiers, 1918.

How Do I Search This Collection?
To begin your search it is helpful to know:
 * The name of your ancestor
 * The approximate immigration and naturalization dates
 * The ancestor’s residence

If you do not know this information, check the 1900 census and calculate the possible year of naturalization based on the date of immigration. The 1920 census may tell you the exact year of immigration or naturalization.

How Do I Analyze the Results?
Compare each result from your search with what you know to determine if there is a match. This may require viewing multiple records or images. Keep track of your research in a research log.

I Found the Person I Was Looking For, What Now?
Use naturalization records to:


 * Learn an immigrant’s place of origin
 * Confirm their date of arrival
 * Learn foreign and “Americanized” names
 * Find records in his or her country of origin such as emigrations, port records, or ship’s manifests
 * An individual may have filed the first and final papers in different courts and sometimes in a different state if the person moved. Immigrants who were younger than 18 when they arrived did not need to file a Declaration of Intent as part of the process
 * If your ancestor had a common name, be sure to look at all the entries for a name before you decide which is correct
 * Continue to search the naturalization records to identify siblings, parents, and other relatives in the same or other generations who may have naturalized in the same area or nearby
 * The witnesses named on naturalization records may have been older relatives of the person in the naturalization process. Search for their naturalizations
 * You may want to obtain the naturalization records of every person who shares your ancestor’s surname if they lived in the same county or nearby. You may not know how or if they are related, but the information could lead you to more information about your own ancestors

I Can't Find the Person I'm Looking For, What Now?

 * Check for variant spellings. Realize that the indexes may contain inaccuracies, such as altered spellings and misinterpretations
 * Try alternative search methods such as only filling in the surname search box (or the given name search box) on the landing page leaving the other box empty and then click on search. This should return a list of everyone with that particular name. You could then browse the list for individuals that may be your ancestor
