A visa is required for all foreign nationals, unless there is a treaty in existence between their country of nationality and South Africa. Currently, nationals of the United States of America, Canada, and the European Union do not require a visa to visit South Africa for bona fide tourism, business, or transit purposes. Applicants who require a visa should submit their completed applications to the South Africa Mission in their country of origin.

This is just a sample of what you'll find in the complete South Africa guide.
