You were born in SA but have dual citizenship??? How did that happen? Normally you have to give up one to get the other in Europe.

I know that it is possible since I have it too but it only applied to kids who were born abroad and had foreign passports. End of the 80's they were required to take up SA citizenship at age 12 if they were in the country prior to 1974. This was done to prevent the boys getting foreign passports to skip the draft back then. Did you by chance already have your foreign passport before and have to re take the SA citizenship?
