An embassy is the nerve center for a country's diplomatic affairs within the borders of another nation, serving as the headquarters of the chief of mission, staff, and other agencies. An embassy is usually located in the capital city of a foreign nation; there may also be consulates located in provincial or regional cities. U. S. embassies and consulates abroad, as well as foreign embassies and consulates in the United States, have a special status. While diplomatic spaces remain the territory of the host state, an embassy or consulate represents a sovereign state. International rules do not allow
representatives of the host country to enter an embassy without permission—even to put out a fire—and designate an attack on an embassy as an attack on the country it represents.
