Hey dear,

You can get 85% quota only to it state you have got domiciled. you'll apply for any state quota 85% seats but at the time of counselling they're going to demand domicile certificate or bonafide certificate which can clearify you belong thereto state.

If you'd fail to deposit domicile certificate then your money are going to be wasted therein counselling.

So you must apply to only those states 85 % quota having domicile or bonafide showing you belong thereto state.

If you've got karnataka and state domicile then you'll be eligible for counselling in both states.

No. just in case you're a resident of province for atleast 6 years then you'll get a domicile made for you by the govt. by applying for it and furnishing documents like tax receipts,school leaving certificate etc.
