Is it Legal to Play Online Poker for Real Money in the United States?
US Federal Laws - Do not prohibit online poker for real money, the seizure of domains and assets of Full Tilt, PokerStars, Ultimate Bet and Absolute Poker were due to unlawful banking practices of these companies in relation to the UIGEA. The online poker sites that I have listed here are not affected.
US State Laws - The one state that prohibits online poker for real money is Washington State where it is a class C felony. No one has ever been charged under this law. New York, Utah, Missouri, Maryland, Louisiana, and Kentucky have vague laws where online pokers legality is a gray area. All other states either approve of online poker or have no laws against it.
The Wire Act - The wire act is a law that prohibits Sportsbooks from taking bets across state lines via telegraph or telephone and also applies to the internet. This makes it illegal for the Sportsbook and not the bettor.
UIGEA- This law was created in 2006 and is called the unlawful Internet Gambling Enforcement Act: This law was not aimed at US Players but at banking and gaming companies that were using certain financial transactions that relate to money laundering. An unregulated Poker Site, Casino or Sportsbook that did not pass the strict KYC or Know Your Client laws for banks created an opportunity for transactions that were used to launder money into the financial system. On certain poker sites 'chip dumping' in heads up games was seen as a possibility for moving illicit funds, the Department of Homeland Security wanted it closed, thus the law. source
Jurisdiction - The online poker / betting sites on this site are all outside of US jurisdiction and are legal and regulated in their offshore countries. Making US interference in an international business a violation of the World Trade Organization to which it is a member. Bet Online accepts players from every state.
Regulation - All the listed poker sites listed on this website are Licensed and Regulated offshore. This means that they are required to meet a lengthy list of regulations most important of which is to provide fair games, segregated accounts for players funds and customer support including problem resolution. If a site is found in breach of any of the regulations and a request to address the problem is not met their license can be pulled.
