Hey!

Your query is not clear to me. I am providing this information in general basis.

You don't need to have domicile certificate for JoSSA counseling. JoSSA works differently, you neet to have 10+2 certificate which will work as your proof of home state. The state in which you completed 10+2 (address of school) works as home state. Suppose you are born in punjab, but you father works in Maharashtra and you completed your 10+2 from Andhra pradesh, then Andhra pradesh will be considered as your home state.

Hope it helped to clear your delimma

Thank you
