Yes, you can extend a South Africa Visit Visa while being in South Africa. It is possible to extend a South Africa Visit Visa under specific conditions like medical emergencies, family matters, or unexpected events. To request an extension, you should go to the Department of Home Affairs a minimum of 60 days before your visa's expiration.
