@Neyawn Sir, please help. I have the same problem. My EWS certificate was issued on 16.3.19 whereas the cutoff date (as per UPSC notification) is 03.3.19. The designated officer was on leave so the whole process got delayed. To resolve this I was provided with an acknowledgement slip dated 02.3.19(which is just a day before the cutoff date). I was told by the circle officer that I can show the acknowledgement slip's date and get the benefits.
Should I use the acknowledgement slip's issue date for filling the date of EWS certificate? Or should I visit the UPSC facilitation centre to change my category back to general? Please help.
