Hello Aspirant,

See if you did not had your EWS certificate at the time of JEE-Main or JEE-Advance 2021 registration then you must have submitted a self declaration in lieu of EWS certificate so now you will have to produce your EWS certificate for admission means after counselling of JEE-Main or if asked to upload for counselling also you can upload it there but for now you don't have to upload it anywhere.

I hope this information helps you.

Good Luck!!
