Here is a brain game, which was shared with me by Chris and Stacy (by the way, thank you a lot!) and which I liked very much. There are a few individuals who are American citizens who can visit 162 sovereign nation’s territories without a passport. They are not subject to customs or immigration controls when visiting and are usually welcomed. They can leave whenever they like and are not subject to U.S. customs and immigration controls when returning to U.S. soil. Who are they?
Please, if you want to solve the riddle yourself, be careful and do not look at the comments of this post, because someone could have already written the solution there. Good luck! You will find the answer in the next brain game. You are always welcome to ask questions about the task, in case something is not clear. But sorry, I will not answer leading questions.
