Additional Notes
State Dept. warns: “South Africa strictly enforces entry and exit requirements and other immigration laws. Failure to observe these requirements may result in the traveler being denied entry, detained, deported, and/or deemed inadmissible to enter South Africa in the future...South Africa requires travelers to have two completely blank visa pages in their passports upon every arrival in South Africa. You will be denied entry and forced to return to your point of origin if you do not have two blank visa pages.”
