I signed up with Banco Nacional the first week it was available. I had been using Direct Deposit in Bank of America. The forms are supplied by USSS and were not clear for switching Direct Deposit. The girl on the 15th floor of the B/N main building worked with me and we got it filled out.
I was very concerned about my deposit being lost in limbo for the rest of my life. Much to my great relief, my deposit was in the B/N on the first try and has been in there, available for withdrawl on the 3rd of every month since.
