A Travel Document is an official paper that allows individuals to travel internationally. It can include various forms of identification, such as a passport, which is the most common type. Travel documents serve to verify a person's identity and nationality, enabling them to enter and exit different countries. In addition to passports, other types of travel documents may include visa stamps, which grant permission to enter a specific country for a certain period. Some individuals may also use refugee travel documents if they are unable to obtain a passport from their home country.
