One other thing I'd like to ask about how much of my loan could be discharged if I'm eligible for an approved federal student loans? Who I can contact regarding this matter?
Yes, as I said, only the portion of the loan that the school failed to return is eligible for a discharge. You can contact your loan servicer for more information.
So, how can I apply for an unpaid refund discharge? My school it' still operating.
First, you should contact your school to try and resolve the issue with them before applying for an unpaid refund discharge.
