It has to be noted that all South African citizens who have been residing abroad and are planning on returning to South Africa, need to first be informed of any news, information or specific laws that may have changed with regards to status within the country while they were absent from the country.
Most South Africans returning home after a number of years, and who have foreign spouses / partners are eager to return, but are advised to seek immigration advice, as to the immigration laws to legally have their partners / spouses reside in their home country with them.
