We have a South African passport. We got 50 days but we want to extend it to 90 days. We are currently in Walvisbaai visiting my brother's son. Do you pay for extension? Yesterday my husband went to ask about extension here in Walvisbaai; they told him N$80 plus. N$ 340 for what i don't know. Have days left, why must we pay? Got 40 days left.
