によるポスト Mazhar Ashraf に サウジアラビア フォーラム
As per previous system you need to pay SR 100 first and then go to Absher and extend visa for one month maximum up to 6 months total. No idea if the fees is same. But be careful do NOT wait until visa expires! you got to extend it 6 days before its expiry Else you face huge fine and deportation. So be cautious.
