you are entitled to leave the country ASAP.

If debts, loans and credit card payments are still pending you will not be able to leave the country.

no way, if you're leaving your bank will engage a third party (75/25)to recover their money. they have ur passport and address details. so third party will file a case in ur country.

On the other hand try talking to the bank customer representative and make a plan to pay back what you have received.

And in the end YES, a public notification of your departure will appear in the newspaper and then everybody will go to you to settle all pendings before finally departing.

Regards!!
