Many banks like ICICI, YES, HDFC etc are not very well aware of the rules for returning Indians and it was a herculean task for me to change my status from Non resident to resident with these banks. My NRE FD's were terminated premature causing interest loss to me and also it took lot of time after informing them about change in my status.
My FCNR, upon maturity was not converted to RFC deposits and it took me lot of time to get the funds transferred to other banks, incurring huge interest loss to me.
I would recommend that all NRI's should have account with SBI only who take care of returning NRI's very much more
