Nonresident aliens are only subject to U.S. taxation on income from U.S. sources. Foreign-sourced income received by nonresident aliens is not subject to U.S. taxation. This is unlike resident aliens who are taxed on worldwide income (income from both U.S. and foreign sources).
Generally, U.S.-sourced income includes all income received from U.S. organizations or individuals and compensation received from both U.S. and foreign organizations or individuals for work performed in the U.S.
Income is considered foreign-sourced if the location of the activity for which the payment is being issued is not in the U.S.
If the source is unclear at the time of payment, the payment is treated as U.S.-sourced income and taxed accordingly.
