Hello aspirant 

If you want to apply for non domicile state private MBBS college then all you need to do is register yourself for all India counseling for 15% seats .In this case you need to give extra amount of registration fees as prescribed by MCC and once you do all of that you have to fill the college of your choice in the choice filling process.

If you get any seat then you have to report to that particular college within three days of seat allotment and there itself you can complete all the procedure and confirm your seat 

So as in for now all you need to do is register for Alq counseling .

Best wishes
