Hello Vinambra,

Persons of indian origin (PIO) and Overseas Citizens of India (OCI) are included in the NRI quota which is 15% reserved and remaining 85% reserved for state quota.

You do not come into the OCI or PIO category. You will deserve All India Quota (AIQ). If you belong from a category (OBC, SC, ST ,etc) then You need to have a central caste certificate { ex. For OBC category - Central NCL } to get admission in your category otherwise you will be considered as General category candidate.

Hope this helps

All the best for your Future!
