I was having Qatar driving licene and was driving in Qatar, recently I have shifted to Oman and applied for Oman licence, Here Authority gave me licence for Oman based on Qatar Licence and eye check up but they have taken the Qatar Licence. I need to go back to Qatar for next six months repeatedly and need to drive cars

My question is
How I can get my Qatar Licence back?
Can I drive in Qatar with Oman Driving Licence/

Please advice
