Fixed deposits are meant to be fixed for a certain period in order to earn certain percentage of interest thereon.

However the banks do accept the request to break the fixed deposit immediately by a written request, there is no question about it. The only thing is that the Bank may not pay you the interest of this period, or they may pay you interest at a lesser percentage (like saving account interest rate).

Your account has nothing to do with your exit permit, however it is advisable to take out the full amount now and close your account. The deposit supervisor is the right person to speak with, because the people at counter may not have enough experience to handle such requests.

if nothing working, then speak with the Deposit Manager or Branch Manager, he would definitely accept your request.
