A Foreign Service Officer (FSO) is a commissioned member of the United States Foreign Service. As diplomats, Foreign Service Officers formulate and implement the foreign policy of the United States.
The United States Foreign Service is a component of the United States federal government under the aegis of the United States Department of State. It consists of approximately 15,000 professionals carrying out the foreign policy of the United States and aiding U.S. citizens abroad. Created in 1924 by the Rogers Act, the Foreign Service combined all consular and diplomatic services of the U.S. government into one administrative unit. In addition to the unit's function, the Rogers Act defined a personnel system under which the United States Secretary of State is authorized to assign diplomats abroad.
