Rather than repeat myself, I'll just link to the comment I made about the rules that relate to civil forfeiture and Interbank Accounts for non-U.S. financial institutions.
I think he was talking about keeping assets in a foreign location, not opening a domestic account in a foreign headquartered bank. Of course, you still have to report any foreign assets to the IRS if the total is greater than $10,000.
