I'm an American married to a Thai woman but we only did the Buddah ceremony. We had a daughter. I'd like to register our baby with the American embassy and get her a passport. I'm heading to BKK in a few weeks and fear I won't have the proper paperwork. I will be taking a copy of the birth certificate that has my name as the father as well as a copy of my wifes ID card. Do I need anything else?
