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.
United States Foreign Service Officers work for the U. S. Department of State in Washington, DC or in 1 of more than 265 diplomatic missions, embassies or consulates across the globe. The short answer to the question of how to work for a consulate is to become a Foreign Service Officer. Foreign Service Officers work with government officials, business people and citizens of their host countries, and help Americans traveling in those countries.
