By all means, keep your home financial arrangem

By all means, keep your home financial arrangements in place while you are exploring new countries.  You never know in advance if you will be staying, or going back home.  In addition, your new country will most probably have different financial products with a different cost and fee structure than you have at the present time.  Most countries have ATMs that can be used to take money from your home bank account as needed, which is useful while you decide if you want a local bank account (if available, with FACTA this is getting more difficult for US passport holders).  Some US institutions will even refund ATM fees when you draw funds abroad, but may require that you have a US residence.  This is easy before you leave, difficult to arrange once you have gone.  Better to be prepared and later decide you don't need the facility, than the other way around.
