What type of business is an embassy?

An embassy is a diplomatic mission generally located in the capital city of another country which offers a full range of services, including consular services.

Is an embassy sovereign territory?

As a matter of international law, an embassy is not ''territory'' of the sending state; it is territory of the receiving state that is accorded, through various treaties and customs, some immunities from host- country law. Defense of an embassy is the responsibility of the host state, not the sending state.
