Hello Aspirant,

As JEE-Advance applications for 2020 have been started and there are so many queries regarding caste certificate validity so let me clear you that if you belongs to OBC-NCL category then your category certificate should be issued on or after April 1st 2020 but if you don't have tha certificate for this date then you should have applied for it in month of June-July when lockdown was being uplifted and as you apply for that certificate you would get a declaration which you can upload on JEE-Advance portal instead of your certificate. Don't worry you are not late at all because still you can apply for your certificate and you will get a declaration which you can upload on jeeadv.ac.in

I hope this information helps you.

Good Luck!!
