In order to get admission for MBBS programme, You need to apply for the counselling of the state in which you want to get admission but for Government seats you can apply only for your state.

If you are asking NEET 2019 admission then you need to apply its application form which is expected to come out in the month of November. Each state will conduct its own counselling on the basis of NEET score.

In case you have any other query then let me know.

Good Luck!
