Please note: We cannot guarantee that the bank will keep your account open or that all services will be available to you, as we do not control the bank and have no access to or influence over your account once it has been opened. The bank could close your account for any or no reason at all as the law allows. That said, the bank is one of the largest in the USA, is very recognizable by name and has clients from virtually everywhere, so unless you give them a reason or the US regulators force them to, it is unlikely that your account would be closed.
IF you are Canadian and you bank with the Royal Bank of Canada, Bank of Montreal or TD Canada Trust, you should be able to walk into your local branch and make arrangements through them to open an account for your Delaware Corporation or LLC in their US subsidiaries. They each have their own retail bank in the USA where they'll open your company bank account for you.
