Hello Aspirant,

See JOSAA and CSAB are two separate bodies for seat allotment in different engineering institutions of India like IITs, NITs, IIITs and so on. If you have been allotted a seat in JOSAA Counselling and you have accepted it and also paid the required amount then the seat is yours and then you cannot participate in further rounds of counselling neither in JOSAA nor CSAB.

For complete details about JOSAA Counselling and CSAB Counselling kindly refer to the link s given below :-

I hope this information helps you.

Good Luck!!
