Hi Aspirant,

Hope you are doing great as per the question asked by you, as your O.B.C certificate is issued on 18th November, 2021 and it is not valid now as the new certificate should be issued every time after 1 April so you need to produce a new O.B.C certificate as per N.E.E.T there is criteria of O.B.C category should be issued after 1st january, 2022 so you need to produce a new category certificate.

Hope you found this answer useful. Stay motivated stay positive.

All the best!
