Gorkhali jetho HEre is What is written in IRS website Nonresident aliens. Generally, if you are a nonresident alien (other than a resident of Canada or Mexico, or certain residents of India or Korea), you can qualify for only one personal exemption for yourself. You cannot claim exemptions for a spouse or dependents. I am going to file 1040 NR. I heard that it should be five years to fill as Resident.
