International Oversight Advisory
A formal body of oversight created and operated by those countries with knowledge of the Stargate and the Stargate program. The I.O.A. is comprised of representatives from (at least) the United States, Great Britain, France, and China -- though possibly including other countries as well. The organization carries substantial influence in determining how the Stargate program is run and funded. They oversee spending and personnel for Stargate Command, the Atlantis expedition, and the ship-building program responsible for the BC-304 fleet.
According to Richard Woolsey, though representatives of the I.O.A. frequently bicker over the use of Stargate Command's resources, they have nothing but the utmost respect for the work the base is doing.
