Unfortunately, laws regarding online gambling in general in the US are a bit complicated, as both federal and state laws determine whether online gambling and live casinos are allowed. The most important thing to know first is that it is not federally illegal for US punters to play at live casinos in the United States.
Many believe that the introduction of the Gambling Enforcement Act of 2006 prohibits live casinos, but that is not the case, so every state in the US is free to regulate its own online gambling market.
In recent years, many states in the country have decided to regulate the online gambling market, and make casinos live in USA completely legal, while others have introduced highly restrictive laws which prohibit live casinos.
So, it mainly depends on which state the punter is in, but the even better news is that although some states say that operators cannot obtain a license to offer live casino services there, nothing stops punters from that state from accessing other live casinos that operate in different states.
Although the states where live casinos are illegal try to blacklist these sites, they have had limited success so far, and there has not been a case where a player was criminally charged for gambling at any live casino.
It is expected that in the near future, more and more states will legalize online gambling, so the number of live casinos in the US will increase even more. At the moment, live casinos are completely legal in New Jersey, Pennsylvania, West Virginia, Delaware, and Michigan.
