Hello aspirant,

YES, it will create some trouble at time of counselling if you will not have the original documents for verification during NEET Counsellling. So, to avoid that, you must need to have the original documents or certificates Before or on NEET Counselling dates.

Further, if you will submit the self-undertaking of your OBC category certificate, then normally, after 14 days you will get your OBC Certificate from the authorities. But, if you won't get it in proper time, then you can complain the authority.

I hope that this will help.
