From time to time I get requests for station transmit privileges from operators outside the United States and its territories.  It doesn’t matter where the control operator is located,  but there is a USA requirement that the control operator must hold an FCC-issued Amateur Radio License with the appropriate privileges.

For more information on the requirements, please follow this link to the ARRL website, which does a great job of explaining it and answering your questions.
