Before planning a trip outside the United States, it is crucial to check the status of your passport. Every U.S. passport expires ten years from the date issued (for adults). If your passport is expired, or if you do not have a passport, you must
register for one at least four months before your trip. This precaution ensures you receive your passport on time.Attention: For safety reasons, it is important to stash a photocopy of all important travel documents at home.
