The interpretation of research activities should not be confused with activities for which a work permit will be required. If an employment position/post is offered wherein the incumbent will be on the establishment (personnel structure) of the institution, then a work permit will be required.:

"work" means business, commercial or remunerative activities within the Republic, excluding work on the basis of a permit referred to in sections 12 or 14, or work for a foreign employer pursuant to a contract which only partially calls for activities in the Republic, or work as a business or profession mainly based outside the Republic but requiring activities within the Republic.

Nationals who are visa restricted must apply for a visa if they wish to enter South Africa for any period not exceeding three (3) years for the purpose of engaging in research activities.

Certain Nationals may proceed to South Africa without a visa, at which point they will be admitted for an initial period of 3 months, within which they may apply for the renewal of their permits in South Africa.
