I have not come across anybody who left qatar for good bcause of this.
but if the scene continues( I hope not...) then definately after year or later many of us may think of leaving.
I agree the salary offered in India is almost equal or little less then offered here. But there are some good reason to be here bcoz there you have to calculate all types of taxes applicable on salaried employee( which is a major factor for counting difference in amount paid)apart from that in India life is rough( though we will be in our own country) but practically if you see, life is cool here.
And if you are here then you are saving some amount and when you are going to your country( in a year or two) that gives you buch of INR( depends on lifestyle on every individual). Here no travel or attending relatives function etc..... so all that firm expenses are saved here and turned into big money when you go on vacation and there you will be for a month or two so for that period the piggy bank money is a lot to spend in short time.

Overall till QR comes between 7 or 8 INR, I feel this place is good as far as life and money is concerned.

Correct pls .... if I have mentioned something incorrect or add something if you feel I miss some....
