Answer:
You are asking business decision questions.
1. If business wants to open an account at your bank and they are not even doing business in your State, why are they coming to you, why do they need a bank account in your State, and do you want to do business with them.
2. If they are doing business in your State and your State requires that they be registered in your State, do you want to do business with an unregistered business.
You need to assess the risks and make your decision. This has nothing to do with beneficial owners.
