i think in all cases whats really worth it is,that for the past and now the normal practice for expats in the whole of the gulf is,that they take a 1 year unpaid leave for example from the origin employer,and come for say a year or so and give it a shot in the gulf(in any country) and see what good and bad points they come up with here.this is the what we are used to here in the gulf.
Some left for a better life and some weighed matters and stayed.some have been here for over 20 years,some built a life finished their kids studies in schools and unis and some even got their big kids jobs in the gulf.
