The judgement that you have read is for Candidates who belong to Karnataka and are OCI Card holders. If you hold the domicile of Telangana, you cannot participate in the Management Quota of other States holding an OCI Card. Telangana has no such rule. So OCI card holders and NRIs do have NRI quota in Private Medical Colleges that they can try for a seat in. They cannot try under Management Quota of Private Medical Colleges.
