Hi, 

If you have been alloted a seat under 85% state counselling and have joined it still then you are eligible for all india counselling

However if under AIQ also you have been alloted a seat then you need to vacant either of the two seats.

Either give up the seat under state quota or the seat under all india quota. Because at once a candidate cannot hold two seats.

So yes you shall be eligible for all india quota counselling.

Hope it helps

All the best
