Even though student loans are non dischargable, they will report just like any other item in the BK. Once a BK is discharged, it will go back to the same status as it was prior to the BK...so if you were current, the loan will be current. If you were in default, the default returns.
It sometimes does take some time for the BK stay to be lifted off student loans...dont ask me why. I have seen cases where the borrower called in a week after only to have to wait 6 months for the account to be come active.
Keep in mind that once the BK is discharged, all interest will be updated that accrued during the BK stay.
Also, and this doesnt happen often...filing BK can cause your loan to default. I cannot remember which but we had a couple of FFELP guarantors that defaulted loans as soon as the BK papers arrived. From what we were told by reps from the guarantor, it had to do with "intent" to pay...and from what they told us it totally legal.
