If you are married with kids forget about coming to Dubai. Costs for your wife and schooling for your kids will be 5X the costs as in the states. Your phone calls which because of the local monopoly blocking tactics are over 60 cents a min overseas. Don't listen to the pack, Sykpe is blocked unless you do some fancy stuff to your computer so plan on spending big bucks on your phone bill.
My advice is you have a job in the states, stay there and enjoy all the offerings. Rememeber no matter what EK tells you it is a 3rd world police state. You have no rights and your sole being in Dubai is to make the ruling family money and you won't make as much money as you would in the states. You might make more money but you won't save as much as you think either. Think long and hard about joining and get all the information you can to make an informed decision.
