OBS_VALUE: ISPs need to obtain general work visas to provide services in South Africa. 18.(3)a(i) states that an employer needs to show a certificate of Department of Labour confirming that despite a diligent search, the prospective employer has been unable to find a sustainable citizen or permanent resident with qualifications or skills and experience equivalent to those of the applicants.In addition, the Critical Skills Work Visa may also apply to ISPs.The Critical Skills Work Visa (from June 2014) replaces the former Exceptional Skills and Quota Work visas. The latter was issued in line with the Quota List of 2009, which had skills categories, requirements, and the quota of skills targeted in the Republic of South Africa. The Critical Skills work visa is issued in accordance with the critical skills list.There are no quotas under the critical skills work visa which means there is no limit to amount of visas issued under this section.The applicant does not need to have an employer when applying nor does he or she need a prescribed minimum amount of years of experience. This is a significant shift from the 5 years post qualification experience previously required under the quota work permit.
