Each index card lists a petitioner's name, address, age or date of birth, and petition number. The "complete and true signature of holder" is also included, but not country of origin. The reverse of some cards may include a maiden name, names of children, and cross-referenced information (including name changes) from related files. This title contains over 23,000 cards. Look for wives and mothers on separate cards after 1922, as women were naturalized separately from men beginning in this time period.
