I know it sounds like a sort of stupid question, but I need to know if its entirely necessary for me to carry a passport to go to Spain if I have a European birth certificate. I haven't renewed my US Passport and my mother booked a last-minute-flight. I only have around 5 days to find out about this. Otherwise, my mom would have to go on her own. I think she'll end up going on her own anyways, but I want to make sure that there is no other option. She cant go with anybody else... so yeah.
Thanks in advance!!
Duplicate post. Already answered on the other one.
You need a US Passport when returning to US, don't you? You also absolutely need a passport to board a plane overseas.
