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. Or else the only other option is through Management Quota. Under All India Quota, All the 15% of All India Quota Seats except for Jammu and Kashmir, 100% Seats at Deemed and Central Universities, IP Quota seats in ESIC Colleges, Seats at AFMC are filled by DGHS. The 85% State Quota and Private Colleges are filled by the respective State Authorities. And there are 3 Categories in Private Medical Colleges. Category A is the Government Quota Seats. And only candidates of the home State are eligible to apply for these seats. B Category seats are also called Management Quota Seats and they are filled through State Counselling and the remaining seats are filled through direct Admissions by contacting the College directly. Here the fees is usually nothing less than 40 lakhs. The last Category is NRI seats Category and you cannot apply for that.

So if you belong to UP, but want to try in Private Colleges, you should try through Direct Admission with an only exception being Karnataka. Karnataka is an Open State and so you can apply for Karnataka Private Colleges through Karnataka State Counselling. Now with a score of 400, you  will have too many options for Direct Admission. At this point in time, only CMC Vellore has released its application forms. Most Colleges release their forms after NEET results.
