MOKGORO J [58] I accept that the concern that non-citizens may become a financial burden on the country is a legitimate one and I accept that there are compelling reasons why social benefits should not be made available to all who are in South Africa irrespective of their immigration status. The exclusion of all noncitizens who are destitute, however, irrespective of their immigration status, fails to distinguish between those who have become part of our society and have made their homes in South Africa, and those who have not. It also fails to distinguish between those who are being supported by sponsors who arranged their immigration and those who acquired permanent residence status without having sponsors to whom they could turn in case of need. [59] It may be reasonable to exclude from the legislative scheme workers who are citizens of other countries, visitors and illegal residents, who have only a tenuous link with this country. The position of permanent residents is, however, quite different to that of temporary or illegal residents. They reside legally in the country and may have done so for a considerable length of time. Like citizens, they have made South Africa their home. While citizens may leave the country indefinitely without forfeiting their citizenship, permanent residents are compelled to return to the country (except in certain circumstances) at least once every three years.61 While they do not have the rights tied to citizenship, such as political rights and the right to a South African passport, they are, for all other purposes mentioned above, in much the 61 Section 28(c) of the Immigration Act. 36
