when a USA citizen marries in foreign country
if a US citizen marries in foreign country, with a foreign person
and if he files his tax return as married filling separately
then the foreign spouse is totally out of the equation from US tax system and no paperwork for her? and all the US spouse must do is to mark "married fililng separately" and that is all? the rest is same as if he is filing single (yes tax rate might be different but as far as what he does when completing return)?
Or, still there will be something, some paperwork for the foreign spouse to USA, just because she marries US citizen but has nothing else to do with US and totally lives and works abroad? if so is that form, whatever it is, is supported here?
