sorry I am a bit confused about this. Say you are recruited by your home country to work in qatar, but when there, you find a better job. You can't quit the first (home) company to join the other (qatar) company? Unless after serving for  2 years and subject to the first company issuing a NOC?

Or lets bring it a little further. Let's say you complete the 2 year stinct with the first company (ie recruited from home country), then instead of returning home, you decide to continue to find employment there, you still need the home company to issue NOC?

Or is this NOC thing only applicable to local (qatar) companies and employees recruited locally? ie recruited after arriving at qatar
