What employers need to know about employing foreigners in South Africa
The employment of foreigners in South Africa is regulated by the Immigration Act 13 of 2002, as amended (“the Immigration Act”). The Immigration Act provides for the admission of foreigners to, their residence in and departure from South Africa and matters connected therewith including the ability of foreigners to work in South Africa.
