As a general rule. blacks from the United States are not permitted to visit South Africa. The basis for this systematic refusal is race. In March 1974. USIS official Richard Saunders and his wife were refused service at a Dunbar hotel while in South Africa on official business. simply because they were black. Congressman CHARLES DIGGS. upon arriving in South Africa in 1971. discovered that the South African Government had reneged on its unconditional granting of his visa. Often. black Americans allowed into South Africa are assigned temporary classifications such as "honorary white" during the period of their visit. Eliminating South Africas quota then is essential for the United States.
