Frequently Asked Questions

How long is an OBC-NCL certificate valid for central government exams?

1 Financial Year only (April 1 to March 31). A certificate from a previous financial year is rejected at DV. This is the most common OBC rejection reason — get a fresh certificate if yours is older than the current financial year.

What is the EWS certificate crucial date rule?

The EWS Income & Asset Certificate must be based on income from the Financial Year immediately preceding the year of application, and the certificate itself must be issued on or before the notification's closing date.

Central Government format must explicitly state: (1) reference to GoI OM/Resolution No., (2) caste name from the Central OBC list (not state list), (3) specific Non-Creamy Layer exclusion clause. A state-format certificate without these elements is rejected even if your caste is valid.
