Hii

If you have the domicile for both the states then you are eligible from both the states but still you need to confirm it on the states official website for medical courses so as to check their eligibility criteria for the 85% state quota.

It is your wish from which state would you like to apply for 15% all india quota as you would be eligible from both the states. 
Rest you can visit the NTA official website and you can also download the information bulletin and check the FAQs section for more details

Thank you!!
