A signed passport is a document that is essential for international travel. However, there are several synonyms in different languages that also describe the same document. In Spanish, it is called a "pasaporte firmado," in French "passeport signe," and in German "unterschriebener Reisepass." In some countries, it may also be referred to as a "sealed passport" or a "stamped passport," depending on the method of authentication used. Whatever the language or terminology, a signed passport always serves as proof of identity and citizenship, allowing travelers to move across borders and explore the world.
