If you dont have a job now, you better take the Abu Dhabi offer, no matter how small it is, at least you have something to earn instead of jobless.

And also get that NOC letter from your prev. comp. in Qatar, so you while you are working in Abu Dhabi, you can look for better job in Qatar, if you like.

Just make sure that new job in Abu Dhabi is on the free go.

Good luck Sir !
