Passport and entry visa for South Africa?

Another question,
Does RSA require a passport OR passport and entry visa? Thanks again

All foreigners must be in possession of a passport that will remain valid for at least 30 days after the intended date of departure from South Africa as well as a round trip airline ticket.

Citizens of the Austria, Belgium, Canada, France, Germany, Ireland, Italy, Japan, Lichtenstein, Luxembourg, Netherlands, Russia, Singapore, Switzerland, United Kingdom and United States of America planning to spend no more than 90 days in South Africa will be issued a temporary entry visa at the airport upon arrival. For a complete list of countries please click here to the South African Embassy web site. As the list changes from time to time, it is important to verify if you need to obtain a visa based upon your country of citizenship.

Persons possessing passports from other countries may be required to obtain an entry visa prior to departure from their country of origin. This should be done well in advance as it can take some time to complete the process which may require sending your passport to their Embassy or Consulate.

Make sure you have at least two blank pages in your passport for visa stamps, more if you are adding stops to other countries in your itinerary.
