Many large financial institutions operate in multiple countries. However, banking regulations can vary significantly from place to place, and there are strict regulations in place about moving money from country to country. As such, few banks operate consumer branches in multiple countries. In other words, you'll have a hard time finding a U.S. bank that operates regular bank branches in other countries. The alternative is to use a U.S.-based bank that offers great digital banking options and low fees on services like foreign ATM withdrawals and purchases in foreign currencies.
