Your bankruptcy can be reported on your credit report for 10 years from the filing of the case. 

Since old debts no longer have claims on post bankruptcy future income, you automatically become more credit worthy.  Once a bankruptcy is discharged, you are entitled under federal lay to have the balance of each discharged debit brought back to "0".  Remember, the history of your past debts can still be reported, only their balance will now be zero and you should dispute the debit is the balance is not so reported.
