The IRS requires a flat 30% withholding on ALL types of payments to foreign national individuals UNLESS: The individual has a U.S. tax identification number (SSN or ITIN) and qualifies for a tax reduction under the tax treaty between the U.S. and their country of tax residency.
If you earned foreign income abroad, you report it to the U.S. on IRS Form 1040. In addition, you may also have to file a few other international tax forms relating to foreign earnings, like your FBAR (FinCEN Form 114) and FATCA Form 8938.

Exemption from withholding To qualify for this exempt status, the employee must have had no tax liability for the previous year and must expect to have no tax liability for the current year. A Form W-4 claiming exemption from withholding is valid for only the calendar year in which it's furnished to the employer.
Payments to a foreign corporation in exchange for personal services performed in the US by either a US citizen or alien is considered to be US-sourced income and is usually subject to withholding. (Can be wages or self-employment income.)
