The actual naturalization volumes vary in size and format. Prior to the late 1800s 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.

After 1906 the entries generally include the name of petitioner; address; name of the court in which naturalization occurred; certificate, petition, or other identifying document number; country and date of birth; date and place of arrival in the United States; date of naturalization; and name and address of witnesses. Although space was provided for this information, it is not always present on every card. Index cards for naturalizations taking place prior to 1906 typically contain only the name of the petitioner, the name of the court in which naturalization occurred, document number, country of origin, and the date of naturalization.

Naturalization is the process of granting citizenship privileges and responsibilities to foreign-born residents. Most 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.

How Do I Search the Collection?
To begin your search it is helpful to know the following:


 * The full name of your ancestor
 * Identifying information such as the approximate immigration and naturalization dates or the ancestor’s residence

If you do not know this information, check the 1900 census and then 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.

Search by Name by visiting the Collection Page: Fill in the requested information on the initial search page. This search will return a list of possible matches. Compare the information about the individuals in the list to what you already know about your own ancestors to determine if this is the correct family or person. You may need to compare the information about more than one person to find your ancestor.

View images in this collection by visiting the Browse Page: To search the collection you will need to follow this series of links: ⇒Select "Browse" link in the initial search page ⇒Select "Name Range" which takes you to the images.

Look at each image comparing the information with what you already know about your ancestors to determine if the image relates to them. You may need to look at several images and compare the information about the individuals listed in those images to your ancestors to make this determination.

With any of these searches keep in mind:


 * There may be more than one person in the records with the same name.
 * You may not be sure of your own ancestor’s name.
 * Your ancestor may have used different names or variations of their name throughout their life.

I Found Who 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.
 * Look for the Declaration of Intent soon after the immigrant arrived, and then look for the Naturalization Petition five years later, when the residency requirement would have been met. Look for naturalization records in federal courts and then in state, county, or city courts.
 * 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 Who I'm Looking for, What Now?

 * Check for variant spellings. Realize that the indexes may contain inaccuracies, such as altered spellings and misinterpretations.
 * Try a different index if there is one for the years needed. You may also need to search the naturalization records year by year.
 * Search the indexes of nearby counties.
