You are interpreting it wrong:
Quote:
No person engaged in the business of betting or wagering may knowingly accept
It is gambling sites, i.e. those engaged in the business of betting or wagering, not financial institutions, who are forbidden from accepting such financial transactions. Player withdrawals are not forbidden by the UIGEA.
In addition, that prohibition is only against transactions for "unlawful Internet gambling". Our laws, with the exception of a few state laws, don't make Internet poker unlawful.
In addition, poker sites aren't actually "in the business of betting or wagering". They merely provide the software platform for players to bet against each other.
In addition, poker isn't gambling by many definitions.
The consensus is that your money won't be at risk. Deposits and withdrawals may become a little more difficult after June 1, but probably not by much. You should have a bank account at a bank separate from where you do your normal banking just for poker transactions, just in case you do run into a hiccup.
