But my point Tom is they surely cant pay tax twice. I cant see how that would work...if they dont have assets in the US then they surely cant be taxed on UK earnings if permanently resident here. If on the other hand they are temporarily seconded here, say working at the US Embassy or similar, but still with a main home in the US, then that would be different of course.
Although, one must say, the tax system everywhere is a source of permanent bewilderment.
