Las vegas you can search the info of cost living in qatar for western at www.justlanded.com I hope it can help you to decide...
I thought living in qatar depends on what you want for the future purpose. If living in USA is hard just take it the offering ..It is good offer.
But if not I suggest you to settle down in USA.
Many Indonesian wanna get job in USA but It's difficult..I am Indonesian.
My dream someday can see and work in unle Sam too.
Just thinking about it....
