PASSPORTS AND VISAS 

All visitors to South Africa must be in possession of a valid passport in order to enter the country, and in some cases, a visa. However, it is important to note that under South Africa's Immigration Act of 2002 (Act. 13 of 2002) in force since 7 April 2003, (a) Immigration Act, 2002 the passport shall contain at least THREE unused page when presenting the passport for endorsements. Failure to have a clear page can result in entry being refused.
Passports need to be valid for a minimum of 6 months after your departure date from South Africa.
