If you're a United States citizen, there are many places you can travel without a passport. Within the 50 states, you can obviously travel freely. You can also travel to several protectorates, including Puerto Rico, the Virgin Islands, and Samoa. American Samoa is the only place in the world that does not allow entry to anyone without a passport, but it is possible to get a special permit for business travel. Outside of the US, there are a few other places you can visit without a passport. These include Saint Pierre and Miquelon (France), Cayman Islands (UK), and the Turks and Caicos Islands (UK). It's also possible to enter some Caribbean countries with an ID or birth certificate. Some countries, such as Canada and Mexico, have agreements with the US that allow citizens to enter without a passport in specific circumstances. So, if you're looking to do some domestic or international travel without a passport, there are several options available to you.
