Tracking Down Naturalization Records

Tracking Down Naturalization Records

If you have immigrant ancestors, you are going to want to know how to get a hold of their naturalization records. Find out tricks to tracking them down and analyzing their records to build your genealogy research.

Every year in courts all across the United States, countless immigrants promise to renounce foreign allegiances and support and defend the Constitution and laws of the United States. The Naturalization Oath of Allegiance to the United States of America is the culmination of a path that begins years earlier—applicants must meet certain residency requirements, demonstrate they can read and write English, complete an interview, pass a civics test and file a series of forms with US Citizenship and Immigration Services. Our ancestors, while perhaps not having to supply quite as much documentation, also had to meet a set of requirements in order to become citizens. The naturalization documents filed in various courts throughout the process can help you track down family history clues. In this guide, we’ll show you how to find them.
 

The naturalization process

The process of naturalization generally involved declaring an intent to naturalize, waiting a specified amount of time, then filing a petition to naturalize. After a hearing, a judge would grant the successful applicant a certificate as proof of citizenship. Laws governing the waiting period and required length of US residency varied over time.
 
The first naturalization law, passed in 1790, allowed free whites who’d lived in the United States for two years and the same state for one year apply for citizenship. In 1795, the residency requirement was increased to five years, and applicants had to give three years’ notice of their intention to naturalize before they could become citizens. A 1798 law, repealed in 1802, increased this to 14 years’ residence and five years’ notice. In 1824, the waiting period after declaring an intent to naturalize was reduced to two years.
 
Until 1922, women rarely applied for naturalization in their own right; instead, they became citizens when their husbands naturalized. After 1922, an alien woman who married a US citizen could skip the declaration of intention and file a petition for naturalization, but if an alien woman married an alien man, she’d have to start her naturalization proceedings with a declaration of intention.

Prior to 1906, immigrants could file for naturalization in any court at the local, county, state or federal level. He might go to the next county’s court if it was closer, or file in a big city court before heading West. Some people even filed in criminal or marine court. A person could even begin the process in one court and finish it in another. A variety of forms were used for those naturalizations, so the information recorded varies from court to court and from year to year. 
 
In September 1906, the Basic Naturalization Act turned the naturalization process over to the Bureau of Immigration and Naturalization (later the Immigration and Naturalization Service, or INS, which in 2003 became the US Citizenship and Immigration Services, or USCIS) and standardized the process of becoming a citizen. After 1906, naturalization papers were supposed to be filed in certain federal courts, although some local courts continued to process naturalizations well beyond that date. In addition, from 1906 on, forms filled out about the applicant were standardized. For more about the history of naturalization, consult the timeline of US immigration laws.
 

Types of naturalization records

Each step in the citizenship process produces its own set of documents. The three created for most naturalized citizens are the declaration of intent, petition for naturalization and certificate of naturalization. In some cases, other records also might be generated.
 
Declaration of intention (also called first papers):
With this record, an alien declares his intention to become a US citizen and renounces his allegiance to foreign governments. Declarations of intention filed before Sept. 27, 1906, usually contain bare-bones information: the applicant’s name, country of birth or allegiance (but not the specific town) and date of the application. A few records of this era show the date and port of US arrival. Declarations of intention filed after Sept. 27, 1906, provide more details, including a more-specific birthplace, port and date of arrival, a physical description or photo, and the names of a wife and any children naturalized along with the husband. The declaration of intention requirement ended in 1952, although immigrants still have the option to file a declaration if they want to.
 
Petition for naturalization (also called second or final papers):
Once an person declared his intention to become a citizen, met the residency requirement and waited the required period after filing, he could submit a naturalization petition to the court. He often filed in the court closest to where he lived. Starting in 1906, second papers typically include the petitioner’s name (possibly his birth name), residence, occupation, birth date and place, citizenship, personal description, date of arrival in the United States, arrival and departure ports, date when US residence commenced, length of residence in the state, name changes, marital status (listing wife’s name and date of birth, if married) and the names, dates and places of birth and residence of the applicant’s children.
 
Certificate of naturalization:
After the applicant completed the citizenship requirements and signed an oath of allegiance (a record usually found along with the petition), a certificate of naturalization was issued to the immigrant. Most certificates contain the individual’s name, certificate number, name of the court where he filed, and date issued. After 1929, the certificate also included a photo. The government didn’t retain copies of these certificates, so the best place to find them is among family papers.
 
Naturalization depositions:
These documents contain statements made during a naturalization hearing by witnesses in support of an applicant’s petition.
 
Certificate of arrival:
After 1906, courts began to require proof that an immigrant had legally entered the country. It was provided in the form of a certificate of arrival, which listed the port name, date and ship of the immigrant’s arrival. A clerk at the immigrant’s stated port of entry would locate his passenger list to verify the date and ship of arrival, often making a notation on the passenger list. The INS would then issue a certificate of arrival and send it to the naturalization court. Certificates of arrival were first issued under the Basic Naturalization Act of 1906; a 1929 law mandated them for every naturalizing immigrant. These certificates are generally included in a naturalization records file.
 
Alien registration files: In 1940, the Alien Registration Act required all noncitizens age 14 and older living in the United States to register. Each registered alien was assigned an Alien Registration Number, or A-number. The registration form, part of the immigrant’s Alien File (A-file), requested a broad array of detail including all names used, date and place of birth, immigration date and ship, activities and organizations, criminal history and more.
 

Clues to naturalization

Not every immigrant filed for citizenship. The following sources can provide clues to whether an ancestor filed and when he achieved citizen status:
 
Censuses:
US censuses in 1870 and 1900 to 1940 include notations about whether a person was naturalized. The year of naturalization is given in the 1920 census. Look at the citizenship columns for the following abbreviations: AL (alien), NA (naturalized), NR (not reported), PA (first papers filed), IN (declaration of intention) and Am Cit (American citizen born abroad, used in the 1940 census).
 
Immigration records:
Examine your relative’s entry on an immigration passenger for annotations regarding nationality and citizenship. A number, perhaps with the note Naturalization Certificate Number, indicates a clerk checked the list to verify the person’s legal arrival. If a naturalized citizen traveled abroad on business or to visit family, the passenger list documenting his return would have a notation such as USC (for US citizen), Nat, Natz or Naturalized. For more information on passenger list notations, see JewishGen.org. Finally, a naturalized citizen who applied for a passport would note his year of naturalization. Look for passport records on Ancestry.com, Fold3 and Family­Search.org.
 
Voter registration records:
After 1906, an immigrant had to be a citizen in order to vote. Voting records vary in availability and location. Check county or city repositories, local libraries, and historical and genealogical societies.
 
Land records:
Immigrants had to file at least a declaration of intention before they could apply for land under the Homestead Act of 1862. At the end of the five-year term, when the immigrant went to secure the patent to the homestead, he had to have become a citizen. Therefore, homestead applications may contain copies of naturalization records. You can obtain these files from the National Archives, the appropriate state’s Bureau of Land Management office or from the county courthouse. If your ancestor was successful in obtaining the homestead, finding the land patent should make it easier to get the homestead application records.
 
Military records:
After 1862, aliens who served in the US Army and who were honorably discharged could apply for citizenship on an abbreviated timeline. This didn’t guarantee citizenship, however. The military service record isn’t likely to contain the naturalization record, but if the veteran applied for a pension, you may locate documentation there. WWI draft records indicated naturalization status as well. Digitized WWI draft cards are on Ancestry.com, Fold3 and FamilySearch.org.
 
 
 

Finding naturalization records

Finding your ancestor’s naturalization records has become easier with the internet age. You should have a good idea of when your ancestor filed and where he lived at the time, because record collections are largely organized geographically, and this information will help you identify the right record. But thanks to the internet, you may not have to figure out which court he used and then pay a visit or obtain microfilm (though we’ll tell you how to do this, too). Here’s how you can find the records:
 
Online:
Start by searching naturalization collections on websites including subscription-based Ancestry.com and Fold3 (look for the Nonmilitary Records collection), and the free FamilySearch.org (use the Migration and Naturalization filter on the left). Your library or local FamilySearch Center may offer access to subscription databases, and/or you can use Ancestry.com’s free World Archives Project index to US Naturalization Records, 1795-1972. you’ll need to choose a collection based on where your ancestor lived. Search these sites for a name, then narrow your search as needed by place, year and collection. An immigrant may be naturalized under his birth name, rather than an Americanized name used in later records.
 
On FamilySearch.org, online collections include mostly naturalization filings in federal courts and state superior courts. If you find a result in an index-only collection—one without an attached image of the naturalization document—use the source information provided in the index entry to seek a copy of the record on microfilm (see the next page) or by mail.
 
If your ancestor filed for naturalization before 1906 in a county court, you still might find records among Family­Search.org’s digitized court records. Many of these collections aren’t indexed, so you can’t search by name. Instead, go to FamilySearch and use the filters on the left to choose United States of America, then the state. Look for court records from your ancestor’s county in the collection list in the middle of the page. Click a title for links to browse those records. Ideally, there’ll be a naturalization index book you can search to find the volume and page number with the record you need.
 
Some county courts, libraries and genealogical societies have put naturalization records or indexes online, such as Cook County, Ill., (home to Chicago) and Hamilton County, Ohio. Try a web search for your ancestral county, state and the words naturalization records genealogy. If you have success in an index, be sure to look for copies of the records. For a state-by-state overview of online naturalization records, check Joe Beine’s Online Searchable Naturalization Records and Indexes.
 
Offline:
If your online search doesn’t pan out, you’ll need to check microfilmed records for the court where you think your ancestor filed for naturalization, visit the courthouse or send a written request. County courts and state supreme courts are the most common locations for naturalization filings, but they also could have been filed at a circuit, district, probate or common pleas court. The Red Book: American State, County, and Town Sources, part of

Ancestry.com’s research wiki, offers summaries of court records available each state.
Before you visit a courthouse, check the website or call ahead to ask about locations of historical records and research rules. Otherwise, look for microfilmed court records in the FamilySearch online catalog. Run a Places search for the county and look under Court Records or Naturalization and Citizenship. You can rent microfilm for viewing at a FamilySearch Center near you.

 
Declarations of intention and naturalization petitions filed in federal district courts before and after 1906 are on microfilm in the National Archives research facility covering the area of filing and through FamilySearch.org.
 
USCIS Genealogy Service:
Naturalization records after 1906 are available online and on microfilm with the above resources, but you also can order copies through the USCIS Genealogy Service. The USCIS is the only source for alien registration records and naturalization case files (C-Files). You’ll first request an index lookup for the file number(s) needed, then order copies of the file(s). Click here for assistance. This is a fee-based service (whether or not a record is found) and the wait is 90 days or longer, so first try the resources mentioned above if possible. 
 

Clues in naturalization records
If you’re looking for an immigrant’s name at birth, place of birth or arrival date, you might find what you need in his naturalization records. Although earlier records might provide only the country of birth, post-1906 records usually provide enough detail to help you find passenger records and launch your research in your ancestral homeland.
Even early records name witnesses who swore to your ancestor’s good character and legal arrival on US shores. In later records, witnesses are named on the immigrant’s oath of allegiance. Always note the names of these witnesses, because they may be family members or at least give you a picture of your ancestor’s social circle. Your ancestors also may show up as witnesses on naturalization applications of their relatives, friends, neighbors or co-workers.

Finally, post-1906 records name the applicant’s immediate family and sometimes give their addresses, helping with your collateral research efforts. Records before that rarely name family, even when a man’s wife and children became citizens by virtue of his application.
 
Declaration of Intent:
 
  1. 1927, immigrants across the United States used this standard form to declare their intention to become citizens.
  2. Details in post-1906 declarations usually include a specific place of birth and a physical description. The description of Frederick’s injury may help identify him in other records.
  3. A married applicant provided the spouse’s name and birthplace.
  4. In 1927, immigrants intending to naturalize had to wait at least two years after filing a declaration of intention to file a petition for naturalization.

Petition for Naturalization:

  1. The top section of this 1901 document records the name of the applicant, Patrick Duffy, his military service and the filing date. Beginning in 1862 for the Army and 1894 for the Navy and Marines, those honorably discharged from military service could skip the declaration of intention and fulfill a residency requirement of just one year.
  2.  In this section, the commissioner testifies that he has examined the applicant and witness, and found the applicant has satisfied the requirements of citizenship.
  3. A witness’ address, signature and testimony on his familiarity with the applicant’s moral character and fulfillment of the residency requirement are included.
  4. Personal information is limited in petitions filed before Sept. 27, 1906, but this one provides the name and address of the applicant, date and country of his birth, date and port of arrival, and US military enlistment and discharge dates are listed. This can help you find the right Patrick Duffy in passenger lists.
