I come under the obc creamy layer category but applied under nc-obc,what are the potential issues i may face?

What do you mean by applied? Did u get an NC-OBC certificate when you actually belong to the creamy layer? These things are really important.You have to make sure the credibility of the document asap. If you are NCL, you have to definitely apply.Otherwise you shouldn't. The charges may come under manipulation or production of the wrong document. Call the helpline or drop a query ticket asap. Sort it out before CAT.

@Abishek I didnt get a nc-obc certificate,I had submitted my regular bc caste certificate at the time of registration as I didnt know what cl and ncl meant.I found out the difference recently when i stumbled across a youtube video relating to this.Yeah will do,thanks for ur reply.
