Entering Search Criteria

Enter the name of the immigrant in the format: last name comma space first name space or period middle initial period (for example, Smith, John D. or Smith, Jos.). The first name and middle initial may be omitted to accomplish a surname search. Searches are not case sensitive: you may use any combination of upper and lower case letters.

Keep in mind the following points when entering search criteria:

  • Remember that before 1922 women were usually naturalized through derivative citizenship and were not required to file separate naturalization papers. Only women who did not have a father or husband who was naturalized were required to file naturalization papers. Try searching for the name of the father or husband if you are unable to locate a woman in this index.
  • No diacritical characters (i.e., accented or foreign characters) were used in this database. For names that contain diacritical characters enter the equivalent English character. For example, to search for the name Maller enter Muller, Wager enter Woger.
  • If you cannot find a person for whom you believe there is a case file, try broadening your search by entering only a portion of the surname (e.g., John instead of Johnson) or by typing variations of the spelling of a surname (such as Johnson and Johnsen).
