Hello aspirant,

Counselling for NEET UG will be conducted after the result declaration both by centre and states. For participating in state's counselling you require domicile certificate and some more documents. If you mention category then also you must have valid proof for it. As you told you don't have valid category certificate for Maharashtra them according to my suggestion you must not fill category because failing to produce proof for category will subsequently lead to considering you in unreserved category. And there can be problem at document verification also if you don't have category certificate.

Hope you get some clarification.
