| Nearly two-thirds of all United States ambassadors to foreign embassies are professional diplomats who have completed the country’s rigorous foreign service program. Political appointees operate the remainder of the country’s diplomatic missions abroad. Missions often include a large staff of counselors and administrators, as shown in this chart. Various advisors, including attachés from other federal departments such as the Department of Defense or the Department of Agriculture, counsel the chief of the mission or the ambassador on specific U.S. policies, but ultimately the ambassador must ensure that U.S. policies are implemented and U.S. interests protected. |
