Hello Aspirant,

It seems you are asking for NEET UG 2022 application process, if not then kindly correct me in the comment section below.

So yes, you can upload the newly issued OBC-NCL certificate during NEET UG correction window or if you don't get the certificate issued on or after January 1st, 2022 by the time of correction period then you can upload the self declaration/undertaking  for OBC-NCL.

EWS certificate that is to be uploaded in the NEET UG 2022 application form, should have been issued on or after January 1st 2022 according to the latest guidelines of Government of India.

In case you fail to upload it (issued on or after January 1st, 2022) at the time of registration then the EWS candidate has to upload a declaration [Declaration in Lieu of Gen-EWS Certificate at (Appendix - IXB) in Information bulletin] to that effect (Reference: No.F.No.20013/01/2018-BC-II).

I hope this information helps you.

Good Luck!!
