Guam is a beautiful vacation spot, and many Americans dream of traveling there. US citizens will need a passport in order to travel there.
Also, if you have a valid government-issued ID, you will be able to board your flight and enter the country. However, keep in mind that a passport is always the preferred form of identification for international travel, so it's always a good idea to have one on hand just in case. In addition, if you plan on traveling to any other countries during your trip, you will need a passport for those destinations as well.
There are a few things to keep in mind when traveling to Guam. First of all, although it's technically part of the US, Guam is located in the Western Pacific Ocean, so it's quite a distance from the mainland. This means that flights to Guam can be expensive and time-consuming. Secondly, although the currency on Guam is the US dollar, there are some differences in coins and bills that can be confusing for travelers. Finally, because of its location, the weather in Guam is quite different from what you're used to on the mainland. It's important to pack accordingly! Despite these challenges, though, Guam is a beautiful and welcoming place, and we hope you enjoy your stay!
