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

United States

What is in This Collection?
This is a digital index of naturalization records from Fold3. The cards are arranged alphabetically by surname. The records are for the year 1918.

The actual naturalization volumes vary in size and format. Prior to 1906, each document was usually handwritten on one page. From the late 1800s and on, printed forms were used. After 1906, many entries were typewritten.

While there were various types of naturalization records, the Declaration of Intent and Naturalization Petition usually had the most complete genealogical information.

The first naturalization act was passed in 1802. Immigrants to the United States were not required to apply for citizenship. Of those who did apply, many did not complete the requirements for citizenship.

Naturalization to become a U.S. citizen was a two-part process: the Declaration of Intent to Naturalize, or First Papers, and the Naturalization Record (including the Naturalization Petition), or Final Papers. The First Papers were normally filed five years before the Final Papers because of the five-year residency requirement to become a citizen.

No centralized files existed before 1906. In 1906, federal forms replaced the various formats that had been used by the various courts. Copies were sent to the Immigration and Naturalization Service (INS), creating a central file for naturalization papers. The INS is now known as the U.S. Citizenship and Immigration Services (USCIS).

Naturalization records are generally well preserved, but some records may have been lost to fire or other disasters.

Naturalization is the process of granting citizenship privileges and responsibilities to foreign-born residents. New York’s counties recorded naturalization procedures in the court records as legal proof of citizenship. The courts handling naturalizations changed several times so the card index was created as a way to quickly access specific records.

The index is very accurate and the information that was current at the time of naturalization was usually reliable. However, there was always a chance for misinformation. Errors may have occurred because of the informant’s lack of knowledge or because of transcription errors or other circumstances.

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
 * Consult the United States Record Finder to find other records
