When traveling, especially internationally, it is important that you think and plan carefully. Every country has its own laws and documentation requirements when it comes to allowing individuals to enter its borders, and there are many things to keep in mind when you leave and re-enter the U.S.
Please be aware of these requirements, and make sure you carry the proper documents so that you can travel and re-enter the U.S. without problems.
