Perhaps we're just lucky, but our Swiss bank was okay with it. We only had to guarantee to have a licensed US tax advisor prepare our US tax returns, filing requirements, FATCA/FBAR etc.

While Swiss banks are a bit crazy about anything related to the US (three years ago or so they just stopped accepting US checks from one month to the next, even though they had previously charged a crazy amount of money for it to be cashed in), I heard that banks in neighboring countries such as Germany are less concerned as long as your bank advisor follows some general guidelines.

I personally would not have gotten the US citizenship due to the negative tax consequences (global taxation), but to each their own. Unless you own substantial assets they can still renounce it in the future if interested.
