Unless the money is really great and badly needed, I don't recommend leaving a stable job in oil and Gas in North America to come here.
Also, please note that there is no career growth what so ever,.. what you get in the beginning is what you will be stuck with for a long time,... maybe you will get a promotion in 3-5 years, if you are lucky. As an expats you have a ceiling that you can't exceed.
of course double standard policies are prevalent here.
