Hello,

As per the new updates the validation of OBC NCL certificate varies with the government. It is valid only for a period of 1 month in Central Government and over a period of 3 months in the state Government.

However since you have received the certificate in 2015, the certificate is not valid anymore. Providing a invalid certificate may violate the rules of ISI. So you need have to renew it.

For the renewal purpose kindly check with your district tehsil court and find the documents you to produce. Later you can visit the tehsildar office where you can get your certificate renewed.

Make sure you renew your certificate as soon as possible and apply for ISI. BEST OF LUCK.

Hope it really helps you.

Thank you.
