谢谢。再问一下,他凭工作申请公民要交5年的tax return吗?多谢啊!
-Yes. That just means USCIS wants to know whether he have done all the repsonsibilities for a green card holder (tax return is required to file each year no matter whether you have income or not). Whether He has income or not, more or less, does not matter to his US citizenship application.
