Passport Control is a security process at international borders where officials check travelers' identification documents, primarily their passports. This procedure ensures that individuals entering or leaving a country are authorized to do so and helps maintain national security. During passport control, travelers present their passports to border agents, who verify the information and may ask questions about their trip. This process helps prevent illegal immigration and the entry of individuals who may pose a threat to the country. It is a standard procedure at airports, seaports, and land borders worldwide.
