Departure / Re-Entry Requirements for South Africans

It is now an offence for a South African citizen to enter or depart the Republic of South Africa using the passport of a different country.
It is also an offence for such a citizen, while in SA, to use his/her foreign citizenship or nationality or duty and liable on conviction to a fine or imprisonment for a period not exceeding 12 months.

A SA citizen, who has dual citizenship or nationality, can freely use his/her foreign passport outside South Africa. However, they must use their South African passport to depart from or enter South Africa.
