I'm glad that I read your story - I have a daughter born in the US and now we are living in the UK.............she did have a US passport originally - but, like Tilly has only ever used her British Passport since the US one expired. Her father lives in the States - and last year was the first time that she didnt get over to see him. We have talked about sending her over this fall...........
So - we may have found ourselves in the same predicament as you and Tilly ---------
Counselling ? The whole of the US community need counselling!!!!!!!
THANKYOU FOR YOUR POST.......and I guess we will be off smartly to the Embassy too.......
