The IRS publishes an instruction booklet to accompany this form; OR
1040NR-EZ: "U.S. Income Tax Return for the Certain Nonresident Aliens with No Dependents." A simplified version of the 1040NR. Most F-1, J-1, and M-1 students who are nonresidents may file the 1040NR-EZ. The IRS publishes an instruction booklet for this form.
