The USA PATRIOT Act imposes several requirements on U.S. financial institutions when dealing with foreign financial institutions, especially those that pose a high risk of money laundering or terrorist financing.
Two of these requirements are:
* Performing enhanced due diligence on shell banks: A shell bank is a bank that has no physical presence in any country and is not affiliated with a regulated financial group. The USA PATRIOT Act prohibits
U.S. financial institutions from opening or maintaining correspondent accounts for shell banks, and requires them to take reasonable steps to ensure that their correspondent accounts are not being used by shell banks indirectly12.
* Performing due diligence on correspondent accounts: A correspondent account is an account established by a financial institution to receive deposits from, make payments on behalf of, or handle other financial transactions for a foreign financial institution. The USA PATRIOT Act requires U.
S. financial institutions to collect and verify certain information about the foreign financial institution, such as its ownership, licensing, and anti-money laundering policies, and to assess the risk of money laundering or terrorist financing associated with the correspondent account13.

According to the CAMS manual 6th edition, the USA PATRIOT Act allows the US government to subpoena documents from foreign financial institutions (FIs) that have no presence in the US (option B). The manual states that "The USA PATRIOT Act provides US law enforcement agencies with the power to subpoena documents from foreign banks that maintain correspondent accounts with US banks or have no presence in the United States" (p. 77).
