Another piece of advice: Do come here, make money, build up your savings, live a happy life BUT don't turn around and abuse Qatar or its people as they differ entirely from your culture and traditions, rule and regulations, morals and morality. I am saying this as this is what many from the west do.
A recent example was when westerner recently posted a comment at Qatar Living terming Qatar as among the most polluted countries in the world. The comment was far from the truth and at best a remark from the hip.. But then I overlook it as some people post comments when they are still not sober after the drinks they have had.
