Without NOC, you will not be able to get a job in Qatar and you started your 2 year ban starting Feb 8th 2013, it won't be until 7th Feb 2015 till you can freely apply. I would suggest to negotiate with your previous company to release NOC or try to talk to them for return to your previous job. Sounds like you are in a tough situation. Another consideration is to go to Dubai and find a job there for couple of months and return back to Qatar after Feb 2015 (thats if you still want to come back to Qatar).
