South Africa’s Constitution says that all South Africans living abroad, and who are over 18 years old, can vote in the country’s national elections.
To do so, you have to register to vote, have a valid South African ID and South African Passport, and submit a VEC10 form to the IEC. The VEC10 form becomes available after the President announced the election date.
If you think you may be registered to vote, but want to verify, go to the IEC website and use your ID number to check.
Then, on election day, go to your nearest South African Embassy, Consulate, or High Commission to cast your vote. (Take your South African ID and Passport with you.)
