Finally, to officially complete the American Citizenship process: update the citizenship status.
It can be done before or after getting the American passport.
What will you need?
-Proof of citizenship: citizenship certificate or passport
-ID: driver's license or passport
-Social security card or the application if you still do not have the card
All documents must be originals or certified copies by the issuing agency. You may take them to the office personally or you may send them on the mail (in which case they will send them back home by mail too). I personally preferred to take them myself, and the schedule of the social security office in my area is from 9am to 4pm.
If nothing else has changed, that would be all. If your name has changed, they will send you a new social security card in a couple of weeks.
And the most important thing is to make sure that all the information is correct in the printout they give you before leaving the window, because there may be errors.
