Under the USA PATRIOT Act, in which scenario would the US not have jurisdiction?

shell banks are banks that have no physical presence in any country and are not affiliated with any regulated financial institution. They are often used by money launderers and terrorist financiers to hide their illicit activities and evade regulatory oversight. The USA PATRIOT Act prohibits US financial institutions from opening or maintaining correspondent accounts with shell banks, and requires them to take reasonable steps to ensure that their foreign correspondent banks do not provide services to shell banks12. Therefore, the US does not have jurisdiction over shell banks operating in foreign jurisdictions, unless they are involved in transactions that violate US laws or sanctions.
