In South Africa, visas for tourism and for visiting family and friends are issued for a maximum of three months. Short term visit visas do not allow the applicant to switch into a longer term South African immigration service and although short term study is permitted, an applicant may not study for longer than the grant of their visa. Where students wish to continue studying in South African for longer than three months a study visa application must be submitted. Unlike a visit visa, a student visa allows the candidate to engage in limited employment, however in both cases permits are issued for temporary residence and candidates must return to their country of residency upon expiry.
