The George P. Shultz National Foreign Affairs Training Center (NFATC) is the United States government's primary training facility for officers and support personnel of the U.S. foreign affairs community. It was previously known (and, due to the facility's rather lengthy name, is still referred to by many) as the Foreign Service Institute, or FSI, and is located in Arlington, Virginia, at what was once referred to as Arlington Hall.
