depend what your expectation is. How much do you have to pay for any expenses back in your home country. Child support , mortgage , car loan etc etc ...

I honestly think your offer is low for western country passport holder. 5000 will get you nothing for a house. Except if you want to share 3 or 4 people in a flat.

Forget about other people that saying your offer is good. Do the math yourself. For them who making 2000-3000 a month and have to rent a room off course your offer is very good. Mind you QL have very wide range of members, from people who making 2000 QR a month to people who make over 40000 QR a month.

And bear in mind the 'exit permit', you cant leave the country if your employer not signing your exit permit.

Once you get here, if you find another better offer / employer, you will not able to leave your company if they dont give you NOC.

Good luck with your decision.
