C'mon Zakir, you make it sound all rosy - which is not the reality. Every place has it's advantages and disadvantages. Saudi Arabia is not a heaven or the best place for all. There are many abuse cases, non-payment of salaries, lack of oppurtunities, slack environment etc. Majority of the westerners in gulf are seniors earning moolah in twilight years.
Yes it is tax free and a big advantage. Safe place, I doubt. Legal trouble is very unfortunate for one. What about errant sponsors?
