I am dual UK-USA citizen residing in the UK. My children are UK citizens. Although technically they are eligible for USA citizenship, we've never got around to doing it (and not sure if I want to).
I'm planning a trip to the USA for later this year with my children - but without my spouse. I expect that I can apply for ESTA for the children (probability of rejection quite low) and have a notarised letter from my spouse (children's mother) stating that she does not object to me taking the children out of the country without her. The trip is for around 1-2 weeks and the purpose is to see family (my parents and other relatives).
Is there anything else I need to think of or do differently?
