I officially changed my name as different from my birth certificate. Will this cause a problem?
The Italian government usually permits name changes in only two situations:
(1) your life is in danger
(2) your birth name is obscene.
If you changed your name prior to applying for citizenship, you must amend your birth certificate. To do so, you generally need to request a change of name decree from your local court, then contact the department of vital records of the U.S. state in which you were born and ask them to amend your birth certificate, presenting the decree as supporting evidence.
