I called the Passport Agency here in the states because I was confused. The fee is $67, I have to send in my passport, two new pictures, marriage certificate (original, which is returned with new passport). She told me they do return my old passport, but I will be getting an entirely new one with new name. Oh and it take 5-8 WEEKS!
Next stop, settlement visa. Damn, Ill be broke after moving over, but Ill be with the one I love forever!!!
