First time very stressed poster. Will try to keep it short. Feeling very stupid so please be kind!
After spending the day researching this online I think I know the answer to this but just wanted to check if anyone had experience of this.
Booked a once in a lifetime holiday to Central America flying via US. All British citizens. Only DD16 has dual citizenship UK/US (born in US). Has only ever had one US passport when she was born which expired years ago. We fly in a week. Have only just discovered she has to go through US immigration on a valid US passport. (Feeling v.stupid) Is that it? Anyone experienced this? Are ESTAs checked at departure airport? Have read that if you can get to US they will allow you through immigration with a severe talking to but feel that's a huge risk. Is our only option now to book new flights not going via US at all.
Apologies not as short as I wanted. Thanks for reading.
