Hey aspirant,

As per the rules, EWS CERTIFICATE is not required at the time of registration for neet exam, all you have to do is select your category as EWS. During the process of counselling you will be needing the certificate as at that time it's verified. So, dont worry about that all you have to do is get a certificate called Income and Assets Certificate', from your local government authority (Tehsil). and this is the proof that is required to avail the EWS reservation. The designated government officer will verify your documents and issue your EWS certificate.

Hope it helps

Good luck.
