Private account in the US is not a problem, just walk into any bank and you will most likely get it within minutes. As for the automatic exchange of information, there is a big question mark are US banks really doing it. There are a few colleagues of mine who are EU citizens with private accounts in the US and they never had any problem. In my honest opinion, I think USA is terrorizing the whole world to report accounts of US citizens abroad, but when it comes to their banks seems like they are not doing it ... because they simply can do whatever︀ they want. This is just my personal opinion.
