Meaning if you sign up for an account with one, you cannot cash out to a US bank account. You would have to have a foreign bank account or work with a friend, and then we get into the issue of money laundering and even bigger crimes and punishments.

If you win a large amount of money, you can have them wire the money directly to your bank. And I bank at Wells Fargo, the most hard-line opponent of working with the online poker sites.
