US Golf Association Overview
As the governing body of golf in the United States, the USGA must protect the integrity and the challenge of the game of golf. To achieve this, the USGA creates and enforces rules for play and amateur status, as well as standards for handicapping and equipment.
To encourage amateur competition, the USGA annually conducts ten national amateur championships and three national pro-amateur championships, including the U.S. Open. The USGA also sponsors teams for international amateur events.
