You are right what you said...
As far as integration is concern, it is not going to work in Qatar unless they are willing to treat everyone equally which will not going to happen, sure not in close near future (Place where people are judged by PASSPORT, paid salaries for same work according to nationalities, what you expect? Integration???

To create integration you need to create just and equal Qatari society which needs lots of sacrifice which Qatari have to learn to live with... I think this is dream than reality in any ARAB world... (not in QATAR only)
