My passport is 5 1/2 years old. I'm trying to decide if it would be worthwhile to change my name since I don't know of any trips abroad I'll be taking in the next few years. Does anyone know how long I can use my passport with my maiden name? Also, I was looking at the FAQs on the government website and it says that to change your name, you need to submit a certified copy of your marriage certificate. The office that issued our marriage certificate told us not to lose the original certificate because an original cannot be reproduced. They would only ever be able to issue a copy. So I'd be quite nervous to mail the original to the US Passport office. TIA!
