Dear candidate.....

Well, the EWS certificate must be issued by the Tehsildar or any magistrate officer to be a valid one. So you must contact the DU directly for further information and enroll as a EWS candidate to avail special privilege. You must provide the necessary documents along with the EWS certificate at the time of admission so that your application may be considered.

Hope this helps you out....

Best of luck:)

Hello yash,

It is valid. There are two methods to get issued the ews certificate. 

First one is tehsildar 

Second is via an agent.

If your certificate is issued by tehsildar then it is valid. Be sure about that. It will be eligible everywhere.

Please comment for further queries.

Good luck.
