I received money from sources outside the U.S. Do I have to report it and/or pay tax on that money? [1]
Nonresident Aliens are not required to report or pay tax on money that they received from sources outside the U.S. If you remain in the U.S. long enough to become a Resident Alien for Tax purposes, then income from ALL sources (both U.S. and foreign) must be reported on the U.S. tax return.
