I get different answer everytime I ask... I was told that changing sponsorship and changing visa is a different thing. My understanging is that if you're on a family sponsorship, the company will still have to apply for a work visa for you as there is a penalty for working without a valid work permit. This doesn't mean that you change your sponsorship - you're still on a family sponsorship. And because you were a local recruit (pressumably have RP already) the company would normally issue you with NOC if you resign.

Oh, can somebody clarify this finally? I searched on government web site and in the Qatar labour law and still no clarity.
