The age on the naturalization certificate is based upon the month, day, and year of
birth the individual alleged under oath when he/she filed a petition for naturalization
with the court. The age on the naturalization record is always as of the last birthday.
An individual's arrival record will not show information concerning names and ages of spouse or children unless they accompanied
the immigration when he/she entered the U.S. This information may be shown on other
INS records. (See GN 00302.970 for special information regarding certain Chinese immigrants.)
