Yes, you have to ask NOC from your previous company, either on visit visa, for you father to apply a visa for you.Your name will still be on the immigration's record as CANCEL for two years and you're not allowed to come again until the Ban uplift. But with NOC issued by your previous sponsor, you can comeback and work again here.
But take a note....one NOC for applying for a visit visa, and another one NOC for transfering your visa to another employer/sponsor.So, you need to ask 2 NOC's from them....
