The United States of America has had a very chequered past when it comes to online gambling. For the past couple of decades, the U.S. federal government has not permitted financial institutions to process transactions to and from poker rooms, bookies and casinos. Many U.S. citizens have had the unfortunate experience of not being able to deposit funds at PokerStars or withdraw winnings from an online casino. The good news is many states have now legalised online gambling within their borders.
