who does the president nominate to represent the us in other countries
Ambassadors of the United States An ambassador may be a career Foreign Service Officer (career diplomat - CD) or a political appointee (PA). In most cases, career foreign service officers serve a tour of approximately three years per ambassadorship whereas political appointees customarily tender their resignations upon the inauguration of a new president. As embassies fall under the State Department's jurisdiction, ambassadors answer directly to the Secretary of State.
