But now they show that your selection will be done on the basis of general category EWS candidate in the month of April 2021. Your EWS certificate validity is up to March 2021. So  you have to renew the certificate as per norms and forms to show the EWS certificate for further procedure of availing the reservation advantages for the post of CISF.
