Forget about NOC issue being resolved any time soon.
Qatar is getting ready for the FIFA 2022 and will need cheap labour to get things ready on time and to keep construction costs low. Eliminating NOC for sponsorship transfer will mean a steep rise in salaries, which means local companies will struggle and price of services will go up. This NOC is designed to facilitate local companies and not for employees, so forget about any change soon. I predict that NOC rules will get more strict.
