Hello,

Non  -  Creamy Layer Certificate is valid only for one year from the date of receiving the certificate

If your OBC-NCL certificate was obtained before 1 year, it is always better to get a new  OBC-NCL before applying for exams. Also, it is advisable to get the OBC-NCL  Certificate  in either English (prefered) or Hindi.

Category/caste certificates and educational certificates are required at the time of document verification for any central government job.

Hope it helps

Good luck!
