I received several loans for different programs of study at the same school and was unable to complete any of the programs or transfer credits before the school closed, is it possible that all the loans would be discharged?
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.
Did you start a program and decide not to continue and move on to another field of study?
No, that is not what happened.
