Under-Secretary-General of the United Nations

An under-secretary-general of the United Nations (USG) is a senior official within the United Nations System, normally appointed by the General Assembly on the recommendation of the secretary-general for a renewable term of four years. Under-secretary-general is the third highest rank in the United Nations, after the secretary-general and the deputy secretary-general. The rank is held by the heads of different UN entities, certain high officials of the United Nations Secretariat, and high-level envoys. The United Nations regards the rank as equal to that of a cabinet minister of a member state, and under-secretaries-general have diplomatic immunity under the UN Charter.
