who does the president appoint to represent the us in foreign countries
United States Ambassador to the United Nations The U.S. Permanent Representative, currently Nikki Haley, is charged with representing the United States on the U.N. Security Council and during almost all plenary meetings of the General Assembly, except in the rare situation in which a more senior officer of the United States (such as the U.S. Secretary of State or the President of the United States) is present. Like all United States ambassadors, he or she must be nominated by the U.S. President and confirmed by the Senate.
United States Department of State The United States Department of State (DOS),[3] often referred to as the State Department, is the United States federal executive department that advises the President and represents the country in international affairs and foreign policy issues.[4] Equivalent to the foreign ministry of other countries, it was established in 1789 as the nation's first executive department.[5]
