Here's a little advice for all of you who have read this thread and are considering coming to the Gulf from a long-timer.
Consider well that you'll be walking into almost exactly the same kind of centre you are working at right now, albeit with different overlays of culture, language, expectations, etc. Once you get your head around those differences, it's not too hard to live, work and enjoy life here.
The factor I'd most like to imprint on your minds is the need to be in a position to walk whenever things aren't going your way. You must be able to "go home' or have a second, or third option before coming here. Psychologically, it makes a huge difference and much of the hard-time moaning comes from those who've burnt their bridges long ago and have nowhere else to go.
Having said that, the kernel of truth about life here lies in almost all the postings you'll read here, regardless of the side you choose to join.
Don't just follow the money trail; there are other good reasons why you may want to come here. Whatever happens, enjoy the process and walk if and when you have to without rancour.
Good luck to you.
