The Office of Treaty Affairs provides guidance on all aspects of U.S. and international treaty law and practice. The Office manages the C175 process, under which the State Department approves the negotiation and conclusion of all international agreements to which the U.S. will become a party. The Office also coordinates with the Senate Foreign Relations Committee on issues involving the Senate’s advice and consent to ratification of treaties.

The Treaty Office is also responsible for managing the U.S. treaty archives, reporting eligible agreements to Congress under the Case Act, publishing texts of U.S. international agreements in the TIAS series, compiling the annual Treaties in Force publication, and registering U.S. international agreements with the United Nations.

The Treaty Office also serves as the international depositary for certain multilateral treaties for which the U.S. has assumed this role, including the North Atlantic Treaty, the Antarctic Treaty, the Treaty on the Non-Proliferation of Nuclear Weapons, and the Biological Weapons Convention.

The Office coordinates and conducts treaty signing ceremonies, including ceremonies that involve the President, the Secretary and other cabinet-level officials.
