I am US my husband is Indian and we live and work in a third country. We have US income in my name but all foreign money is in my husband’s name. Is it possible to file “married filing separately “ and write in nra (non resident alien) in place of spouse ssn or itin? Or must he get an Itin? If I can write nra I can only claim my income and leave the foreign stuff in my husbands name out, correct?
