Hey,

Usually different states have different criteria of domicile. As far as your question is concerned, if you have a permanent residence in bihar then you are eligible for the Bihar 85% quota during NEET counseling. Along with it if u have completed your higher secondary schooling from Jharkhand, you can avail the benefit of state domicile over there also.

So a student can avail  multiple domicile as far as the criteria to prove your domicile is satisfied.

Hope that helps.

Thank you.
