@amitrawat09 that is correct --- absent any need for exercising Treaty benefits, for most tax purposes there is no difference between taxation of US citizens/Resident Aliens ( Green Card ) and Resident for Tax purposes. Thus form 1040 only allows for a foreign address ( again used by Citizens/Residents alike ) but there has never been and currently there is no place for citizenship or other immigration status information. IRS collects only information that it needs and is allowed by the statutes or rules ( under its rule making authority ).
