If you belong to West Bengal, you can use your OBC-NCL certificate only in West Bengal Counseling and All India Counselling if this Community is listed under Central OBC list. If you do not have Bihar domicile, then you can only participate as a General Category Candidate. Outside State Candidates will not be able to use their Category for reservation benefits. They can only try for Management Quota seats in Private Medical Colleges and other seats. And they will all fall under Open Category only.
