Temporary Entry work visa- cancellation

Hello everybody!!
I need an advice. With new law in place if i enter Qatar with temporary work entry visa ( i stamp my passport with entry only) and i give up the job offer before residency visa is done and current sponsor make entry visa canellation, I will be banned to find another job and new sponsor to make new temporary visa entry?? Or after entry visa cancelation I still can find another job in Qatar without NOC?

i think u've to got a job offer from the new company in case u find another job then u'll exit & inter again wz the new visa but i'm not sure
it's better to go to labor affair office to ask about that or otherwise try to check online if u've the right to ask for noc or not
