Hello Student

As you belong to OBC category student with the sub caste of chasa in Odisha.If your cast is included in the state  list of the state of Karnataka then you will get the OBC certificate from the state of Karnataka. On the other hand your caste is listed in Central list then you may get OBC certificate from any of the states you you are residing at. But to get OBC certificate from any other state other than your birthplace then we have to you show your domicile certificate as per norms.

Hope this will help.
