A passport is an official document issued by a government that allows a person to travel internationally. It serves as proof of identity and citizenship, containing important information like the holder's name, photo, and nationality. When traveling to another country, a passport is usually required to enter and exit, making it a vital item for globetrotters. In addition to facilitating travel, a passport can also provide access to various services and protections while abroad. For example, if a traveler loses their passport, they can seek help from their country's embassy or consulate, such as the U.S. Embassy or British Consulate, to obtain a replacement.
