Hello Nilesh!!

During Jossa counselling your are floating till last round if you will not freeze your choice  and you don't need to reporting centre.If you get ur desired seat in mid of counselling then you can freeze your option after proper verification but in last round your alloted seat will automatically freeze.

Hope it helps!!

Hi Nilesh Kumar,
If you once choose the float option at reporting centre in first or second rounds in JoSAA counseling then you want float option in further rounds, there is no need to report at the reporting centre for the same option. If you want to change the float option to freeze/slide option then you need to report at reporting centre. If you want to freeze the seat then you need to report at the reporting centre. Otherwise there is no need to report at the reporting centres.
Thank you.
