Travellers to South Africa need to have a passport that is valid for at least 30 days longer than the length of their intended stay. There should be no less than two blank pages in your passport. Passengers travelling to South Africa with passports which do not comply with these requirements, will either be stopped from boarding the aircraft or risk deportation upon arrival in South Africa.
Visitors who stay in the country after the expiry of their permit will be declared "undesirable" for between one and five years; essentially barring them access to South Africa for as many years.
The new regulations require visa and permit applicants to present their application in person. Agents may still accompany you through the submission process but cannot undertake the submission on your behalf any longer.
It is mandatory for visa and permit applicants to have biometric information collected either upon admission to South Africa or upon application for a visa or permit while resident in South Africa.
Yellow Fever certificates are required on entry to South Africa if you have previously visited a Yellow Fever risk country.
Visitors to South Africa as well as South African citizens leaving or entering South Africa with children under the age of 18 need original or certified copies of documents that prove the children are either travelling with their parents, or with the consent of their parents. The specific documents required depends on where the child is from, who the child is travelling with or any other special circumstances (adoption, foster care, whether both parents are still alive, etc). A valid visa and passport may also be presented.
