United States Department of State

The United States Department of State (DOS), or State Department, is an executive department of the U.S. federal government responsible for the nation's foreign policy and international relations. Equivalent to the ministry of foreign affairs of other nations, its primary duties are advising the U.S. president, administering diplomatic missions, negotiating international treaties and agreements, and representing the U.S. at the United Nations. The department is headquartered in the Harry S Truman Building, a few blocks away from the White House, in the Foggy Bottom neighborhood of Washington, D.C.; "Foggy Bottom" is thus sometimes used as a metonym.
