Historic Naturalization Record Search Request

Historic Naturalization Record Search Request

The printed, stamped, and mailed naturalization packet is intended for individuals needing the documents for official purposes such as dual citizenship applications.

The packet will contain some or all of the following documents:

  • Declaration of Intention
  • Final Papers (Petition and Record)
  • Letter from the Minnesota Historical Society library manager verifying the authenticity of the records and also explaining why we are not able to certify the documents
  • Citations for the records
  • Letter explaining the research process and researcher notes if the requested record is not found, or only partially found

Each document is printed on 8.5x11 paper. On the reverse side of each document is the Minnesota State Archives stamp.

Packets are mailed through the USPS. We are not able to expedite the document delivery.






For this research service, Library Staff will search for one individual per request, and will look for both First and Final Papers.

About This Research Service

The research process:
Library staff will search for the Minnesota naturalization records of one individual. If researchers are unable to find any documents in the specified county–or if they only find limited records for the subject in that county–they will expand the scope of the search to greater Minnesota. 

Researchers do their best to find all the official archived naturalization records that pertain to an individual (i.e. First Papers and Second Papers), but sometimes only one set or the other can be located. Whatever is found will be sent to you.  If partial records or no records are located, you will receive detailed research notes.  

Researchers use various search systems and indexes to confirm and expand upon information provided at the time of the request.  In some instances subjects may have naturalized in other states or in the Federal system. If such information is found we will send that to you along with detailed research notes.

Please note: Descriptive research notes are a part of the service whenever full records are not found.  They are designed to help recreate searches and/or find records outside MN State Archives collections.  The notes reflect the genuine process of the researcher(s) and except for correction of errors they cannot be altered after creation.

Official, certified copies:
The Minnesota Historical Society cannot issue certified copies of any naturalization records from our collections. However, we can stamp each page of a physical copy, demonstrating that your copy came from the Minnesota State Archives collections. Stamped copies have been accepted for various U.S. and international purposes in the past.

Please choose the “Printed, Stamped, and Mailed” delivery option if documents are needed for an official purpose. 

More information about Naturalization records:

MNHS holds naturalization records from all 87 Minnesota District (County) Courts and the Minnesota Supreme Court. For most counties, these records date from the 1850s through the 1940s. The usual process had two parts: a Declaration of Intent (First Papers) and a Petition for Naturalization (Final Papers).

Most people filed their naturalization paperwork in their county of residence, but if you know or suspect that the immigrant would have traveled elsewhere to file, please provide that information in the Order Comments box.

After the county courts stopped granting citizenship in the 1970s, all naturalizations went through the federal courts. MNHS does not have federal records. Historic records filed with federal courts in Minnesota are held by the National Archives regional offices in Chicago and Kansas City.

Modern citizenship records are held by the U.S. Citizenship and Immigration Services office, a part of the Department of Homeland Security. If you need an official copy of your own records, please request a copy through their office.

Records of minors and women
Minors were very rarely individually naturalized; they took their citizenship from their parents. Also, most women were not naturalized in their own right until 1922. Prior to that year, a woman was considered to be naturalized if her husband or father received his citizenship.
