Here’s the thing. It’s every bank that is on the SWIFT network because the US is a terroristic state when it comes to financial spying, sorry “transparency”.
Demanding KYC and reporting all your transactions via SARs is the standard thing for all banks. The only ones that get away with not having to do it are the manipulative criminals who schmooze there way in with tellers and do transactions that way. But that’s also stopping with the crackdown at large.
I keep accounts in the US, but I have moved as much as I can out. If you’re in the position where you’ve got high 5 figures or more it may be worth it to setup accounts outside the USA in countries that are hostile to the US banking system. If you are in the position where you can drop $250k on a new citizenship, then get it. Then open accounts under that passport in countries that don’t comply with the US.
Otherwise, you’re screwed. This is why crypto and BRICs are a big thing.
I have many citizenships, one specifically for banking. They look at your birthplace but really it’s your passport. They are required to report US citizens, which are passport holders (because you’re outside the US). Having a second passport or third or whatever, doesn’t bring it up. You must falsely claim you are not an American in friendly countries and then you’re fine. They are very aware of renunciation and don’t require proof. The proof of a secondary passport as your primary is all that’s needed. For example you entered the country on your other passport, that’s where your visa is tied to etc.
The other way with unfriendly countries is even easier. For example if you open a TBank account in Russia, it takes about a day online and they courier you your debit card and bank documents to your hotel. So it requires 2 days in Russia. Even as a US citizen, on a US passport, they do not comply with FACTA. Your accounts and transactions will never be sent to the USA.
You as an American must still report those assets on your taxes. So again, choose whether you want privacy or being a “white collar criminal”
