These records include the index to Declarations of Intention, Naturalization Records, and Petitions for Naturalization filed at the Okanogan County Superior Court between 1890 and 1968. The index will give information about the applicant and what documents are included in the files. Please note that Volume 7 of the Petitions with the records dating from 1937, 1938, 1939, and 1940 (document numbers 506, 507, 509-550) is missing from the series and therefore not included here. Persons interested in finding records for the missing dates for Okanogan County need to inquire with the appropriate federal government agency in charge of immigration and naturalization.

For the best search results, search by name. Search by either last name, first and last name, or just the first letter of the last name. The document year is the date of entry into the United States.
