You could if you are eligible due to an unpaid refund by your school after you withdraw from school.
Did you withdraw from school after receiving a direct federal loan or an FFEL Program loan?
I did, yes.
Then your school may have been required under federal regulations to return some or all of the loan money to your servicer, if they didn't then you may be eligible for a discharge of your loan.
I secured multiple loans for various programs of study at the same school,  is it likely that any of the loans will be forgiven even if I was unable to complete any of the programs or transfer credits before the school closed?
The only loans eligible for discharge are the ones for the program you didn't get to complete because of the school closure; not the ones you decided not to complete on your own and moved to another program.
How much of the loan can be canceled?
Just the portion that your school failed to return.
How can i identify my loan servicer? do you have information?
very easy call the FSAIC Federal Student Aid Information Center at 1 - 800 - 433 - 3243.
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.
And what could I do in case the school is suddenly closed down?
