To find out if an online gambling site is legal and licensed in the US, look for the regulator’s seal of approval in the page footer. If the site is licensed, you will find the logo of the appropriate state regulatory authority — such as Michigan Gaming Control Board or New Jersey Division of Gaming Enforcement. If you are still unsure, you can cross-reference the information with the list of licensed operators on the state regulator’s site to confirm that the license is real and valid.
