Online Indexes and Records

You can use the following sites to search indexes to some of our naturalization records. If you find a record and want to obtain a copy of it, please follow the procedures outlined in our naturalization records page.

Free sites

Online indexes are available at the web sites of the German Genealogy Group and the Italian Genealogical Group. These sites are free and can be accessed from anywhere. They also provide indexes to New York area naturalizations held by other repositories and information on how to obtain copies.

Select petitions for naturalization can be found online as well.  FamilySearch currently provides access to some petitions for naturalization, declarations of intention, and other naturalization records in our holdings. Please see the table above for information about which records are available and to link directly to the databases that maintain the records.
