Hello aspirant

hope you are doing well and safe. With reference to your query,  I would glad inform you that it totally depends on the category in which you are getting the admission . If you are getting seat in some quota like sc ,st and obc then surely you have to submit your category certificate . If you want to apply for the fees waiver then you have to submit your income certificate and if you want to apply for state reservation seat then you have to show your domicile

Hope you found this answer informative. Best wishes for your future
