Im a US citizen with a son who has aspergers. If I want to marry a UK man and work over there how have laws changed? Do I have to file taxes in the US every year and how does healyh insurance work for me? Also my 15 yr old son has aspergers. If I can't take him till he turns 18 because his father won't agree will I be able to get him a visa to live and work over there at 18 if Im married and still living there? Can I site his disability?
