Hello beatanangolo0,
Welcome to ²ÝÁñÉçÇø
Since you are already in Namibia, the best way to get accurate information will be to check with the civil status office about the requirements for a foreigner to marry a local person in Namibia.
You will certainly get all the information and help you need.
All the best,
Cheryl
