Hi my mum is moving to the USA to live with my american step dad, and I was hoping to go and join her with my kids once my eldest has done his A levels. I have 3 children ages 18 15 and 9. They would be 19 16 and 10 or thereabouts when I wanted to move. my ex hasnt been part of their lives for two years, would be three years when I apply for visas. There is no court or anything in our case. He has no interest in seeing the children. Is their a age where they can go abroad without his permission, is it from 16 as they can get adult passports then?. Will I have to wait until my youngest is 16?. Thanks for any help in this x
