The main benefits of financial emigration are:
You will enjoy easy access and transfer of your South African funds if you live in another country.
You have the rare opportunity to access and transfer any retirement annuity, as well as pension, provident and preservation fund savings before the maturity date.
No, you will not lose your South African citizenship if you financially emigrate. Some people confuse the change of residence status with giving up their South African citizenship, but this is not the case. After financial emigration, you will still be a South African citizen, unless you decide to either apply for dual citizenship, or obtain citizenship from another country and then give up you SA citizenship.
