Effective 1 May 2015, holders of business visas and all categories of work visa are allowed to register and undertake part-time studies with appropriately registered/established higher learning institutions.
This is relevant to all
foreign nationals holding work visas (Intra-Company Transfer, Critical
Skills & General categories) or business visas, wishing to further
their studies part-time at a South African university or college. These
foreign nationals now no longer require additional permission to study
part-time, and may do so under the auspices of their existing visas.
It is important to note that full-time study is strictly prohibited for work and business visa holders in South Africa. Note also that the duration of the course of studies must not exceed the validity of the foreign national’s existing work or business visa.
