I think coming to Qatar is little risky specialy coming to private sector its either doctor or executive class. Compare to other place in gulf Qatar is little uncertain place. Usually employee not getting salary on time and on leaving employers are not willing to give the gratuity and other end of service benefits. In my view before taking any risk of coming to Qatar better explore some alternative. and cost of living very high. So be carefull before joining any private sector and once you join, you will not be having much options.
