Exceptional/Extraordinary skills under South African Immigration Law are seen as an academic study and/or a profession that is truly inimitable and unique.  The application for an exceptional/extraordinary skills work permit application should be extensively documented and beneficial for a particular working environment in South Africa. If you have such skills or qualifications you may not only apply for an exceptional/extraordinary skills work permit but also for permanent residence.
