Shankar, Private Medical Colleges do not participate in All India Counselling and the seats are filled through State Counselling alone. And for appearing for State Counselling you need to hold the domicile of that particular State. But Karnataka is an exception which means though you do not hold domicile of Karnataka, you can participate in their State Counselling process.  There is no other entrance examination for admission to Medical Colleges in Karnataka for that matter across India other than through NEET. Once NEET results are announced, KEA will release the counselling dates and  you can register yourself subjective to scoring the required cut off.
