Hello sadi 

There is no problem for your counselling. 

After applying for counselling through JOSAA, after got a seat in first round you should go to a counselling center near you where you should verify your documents and you should keep your option that float, freeze or cancel.

There you should submit your documents, if you submit documents to prove you as gen- ews category then you will get that category if not you were removed from that category and you will be added to general category and further counselling will be continued in general category there is nothing to worry.

All the best for your counselling.
