I would really appreciate if someone could help me because I'm totally confused by my sons passport requirements. I'm an American and my OH is a British Citizen and he was born here. (Not sure if that's relevant?) We are in the process of getting our 6 month old son his first passport but the document requirements don't make sense. Do we need to send both my OH's birth certificate and passport? Or can we just submit his passport? Sending both seems redundant and we only have his passport readily available but I don't want the application to be rejected.
