Investing in the US - What Are the Best Practices?

People are having their mortgages called or unable to refinance mortgages because the bank doesn't want an american citizen to have a loan with them. What we hear most often is that people maintain accounts in the us. If you've got a regular vanguard account like i haven't heard of vanguard closing people's accounts, but it doesn't hurt. I've heard of people setting up and using things like mail box forwarding, or having the mail go to their parents houseon. And those things make your life a lot easier anyway,. Because if you're trying to get mail overseas from the us, it doesn't always get there. It's not always reliable.
