my suggestion..
My suggestion is... if you have a secure job in Europe or anywhere in the civilized West stick to it.
I did your same mistake and I'm still paying the consequences.
In the ME there is no job security. You might find yourself in trouble for a number of silly reasons. Ask your self why EK is finding it so hard to crew their planes. They are more desperate and continoulsy lowering their minima. Furthermore it is most of the times a one way ticket and after a few years ( months? ) Dubai starts really to feel tight and you tired of bouncing from mall to mall for 9 months a year.. You will spend enourmous amount of money cause that is how everything is set up .. to make you spend. Dubai's money stays in Dubai.
