There is no such statement as sponsor will give NOC in or on any condition.

If he willing to give he will give else no.

And, it is surely depends on the relation that you have developed with him.

If u feel that you may need NOC, you must start working on it from that point. You should become a person that ur sponsor will give NOC to you.

NOC is not something forcing/fighting and getting. You cant demand on it. It is something giving with the willingness.

So, be good on your work and try to win your sponsors and bosses heart and get it.
