Browse by the first two letters of the last name, then look for the surname, then the full name of the immigrant. Typing a name into the search box below this browse title will lead you to all parts of a petitioner's records. Some extra documents are filed separately and not necessarily "packaged" with the petition and declaration for one individual. You may also locate an oath of allegiance or arrival record this way. After 1930, declarations of intention often include a photograph of the immigrant.
