(a) Except as specifically provided in paragraph (b) of this section, there are no nationality restrictions on employees or consultants of either contractors or subcontractors providing services under an USAID-financed contract, except that they must be citizens of a Geographic Code 935 country, or non-U.S. citizens lawfully admitted for permanent residence in the U.S.
(b) For USAID-financed construction projects where the contract is awarded to a U.S. firm, at least half of the supervisors, and any other specified key personnel, working at the project site must be U.S. citizens or permanent legal residents of the United States.
