Searching for Multnomah County, Oregon Naturalization Files

By Connie Lenzen, CGSM

Naturalizations are some of the most-difficult records for a genealogist to locate. This is due to the cumbersome, disjointed processes that have prevailed. Prior to 1906, naturalization could take place in any court of record—at the city, county, state, or federal level. The various steps of the process might well have transpired in various courts across several states.

For the researcher who suspects their ancestor was naturalized in Multnomah County, Oregon, the process is complicated by the fact that naturalizations were granted by county courts and by federal courts—all located in Portland. Many of the records have been collected in archives far removed from the courtroom where the ancestor swore allegiance to the United States.

For handy reference, this web page is broken down into the following sections:

Was the Ancestor Naturalized?

The first step is to determine if the ancestor was really naturalized. You may be able to find the answer to this question by looking at the 1900, 1910, 1920, and 1930 censuses. There is a column for citizenship status on all four.

If the ancestor voted, he was most likely naturalized. A set of Multnomah County voter registration cards for foreign-born voters for the years 1916 to 1967 was microfilmed by the Multnomah County Election Department. The card includes the name of the court where the voter was naturalized and the date that the naturalization occurred. To see what's on the cards, click here.

A Brief Summary of Naturalization Laws

The naturalization process has called for a declaration of intention, a petition for naturalization, depositions of reputable witnesses, and a final decree. Most pre-1906 records in Oregon provide the bare minimum of information: the name of applicant and his country of prior origins. Post-1906 records can provide ages, occupations, personal descriptions, dates and places of births, dates of emigrations, ports of embarkation and arrival, marital status, and similar information on children of the applicant.

Year Law
1790 First United States Naturalization act enacted. Free white males over 21 years could apply for citizenship before any court of record after two years residence in the United States and one year in any state. No declaration of intention required. Naturalization could take place in any court of record.
1795 Three-year residence requirement for declaration of intent. Residency requirement for final papers increased to five years with one year in the state. Wives and children automatically became citizens (called derivative citizenship). Single women over 21 years could apply for citizenship.
1802 Citizenship bestowed upon widows and children of alien who had declared intent but died prior to final papers.
1862 Military veterans became citizens after honorable discharge.
1906 Bureau of Immigration and Naturalization formed. Aliens required to register upon entry. Residence: two years to declare intent, five years for final papers. Wives and minor children became citizens when father/husband was naturalized (derivative citizenship).
1922 Women aged 21 years could become citizens. Wives no longer became citizens upon husband's naturalization. Residency requirement for declaration of intent waived.

Naturalization After September 1906

All courts conferring citizenship since 1906 have been required to use the standardized forms provided by the United States Naturalization Service (INS). They forwarded copies of the records to INS and now to the U.S. Citizenship and Immigration Services (USCIS). Thus, post-1906 naturalization documents on any person may exist locally or federally, and the INS/USCIS copy is housed in a central repository.

The importance of these records is that USCIS maintains a general index by name! They will search their index and provide copies of the documents. A caution: Records created within the past seventy-five years are deemed confidential, and there are restrictions on their access.Go to the USCIS web site. Click on the “Genealogy” link under "Services."

Just like naturalization is a two-step process, the search is a two-step process. First you apply for an Index Search ($20.00). Search results are returned to the researcher, along with instructions on how to request the file(s) from USCIS or the National Archives.

The index search is important because USCIS will check the following record groups:

The second step is to request the records. Given the index search results, you can order the files. The fee is $20.00 (if the record is on microfilm) or $35.00 (if the record is in manuscript form).

The search takes from two months to one year to complete.

There is often a copy of the naturalization file at the court where the naturalization took place. For an example of the 1913 naturalization of David Holden Forbes, click here.

Naturalization Before September 1906

It is more difficult to locate naturalization records created before September 1906 since there is no master index. The courts in each locality where an ancestor lived must be searched. Even when a file is discovered, it often does not provide much information. As an example, click here to see G. B. Boitano's 1893 Declaration of Intention.

Did your immigrant ancestor receive Federal land? If so, he or she was a citizen. Under the Homestead Act of 1862 and the Donation Land Act of 1850, applicants had to be citizens to receive federal land. A copy of the naturalization papers is included in their Land Case File.

Search Land Patents on-line at: If you do not have Internet access, check the Index to Oregon Donation Land Claims, a book published by the Genealogical Forum of Oregon (GFO). Also, look at the BLM Tract Books, on microfiche, in the Forum Library.

Genealogical Forum of Oregon Library ($7.00 visitor fee)
2505 S. E. 11th Avenue
Portland, Oregon 97214

The Forum has a research service, and a member of the Research Committee will look up the information from the Index to Oregon Donation Land Claims for you. The fee is $10.00 for an hour or research. Photocopies are an additional 25-cents per page. Please enclose a long stamped, self-addressed envelope with your request and send to:

If you find that your ancestor had a Homestead or Donation Land Claim, you can obtain a copy of the entire file (including the naturalization papers) from the National Archives. The fee is $37.00. Request a copy of NATF Form 84, "National Archives Order for Copies of Land Entry Files," from the National Archives. You can send an e-mail request for the form to Or, you can download the form. Mail requests for the form should be sent to:

National Archives & Records Administration

Washington DC 20408-001

The Genealogical Forum of Oregon Library and the Oregon State Archives have the microfilmed set of Oregon Donation Land Claim case files, but the files do not include the naturalization papers. When the files were filmed, it was not permitted to copy naturalization papers.
