We have a very good business customer (travel industry) who does business with a company on London. The London based company does not have an office in the U.S., however they would like to open an account in the U.S. to make their U.S. transactions (wires) easier. We are considering this potential relationship & if we decide to open it, what type/kinds of specific documentation should we get? Articles of organization, w-8 or w-9? I have spoken to our regulatory agency, secretary of state & several bankers with decades of experience, and no one has given me a straight answer, so I'm looking for any additional information I can get. HELP!!
