A South Africa Visit Visa is usually good for 90 days from when it's issued. It can allow either one or several entries, based on what you asked for in your application. Even if the visa is good for longer, you can't stay more than 90 days in a row unless you get an extension. People coming to South Africa should keep track of their entry and exit dates to make sure they don't stay longer than they're allowed, or they might face penalties.
