Agrahari vaishya is a subcaste of vaishya is entitled for OBC reservation in Bihar. I mention my title as agrawal and my great grandfather used to have title Gupta . it is also said that Agrahari is a part of Agrawal community as agrahari is a part of kashyap gotra and agrawal can belong to any of 18 gotras. Now, the person at local level who verifies this can't verify gotras as no government document will require mentioning of gotra. but I have to appear for UPSC and I am already 30 hence I need to use OBC quota.please enlighten.
