for anybody thinking of coming to Dubai regardless of your occupation think long and very hard.
You should also be very clear in your head why you want to come here.
To help you with your decision:
Dubai is a wonderful place to be. It is a mixture of many things, no issues with the locals as long as you accept that you are in THEIR country. The list goes on and on. Generally speaking though, you will either love it or hate it, no middle ground.
However, if your main motivation is the misfounded belief that you are going to make your fortune.....stay where you are as you will be disappointed.
