Why Are Visas Needed for International Travel?

Visas are required to travel from one country to another primarily for security, regulatory, and immigration control purposes. They allow countries to manage and monitor the flow of people, ensuring that travelers meet specific entry requirements, such as health, financial stability, and criminal background checks. Visas also help governments regulate who can enter, stay, and work within their borders, protecting national security, economic interests, and cultural integrity. Additionally, visas enable countries to enforce policies on immigration, prevent illegal immigration, and control the length of stay for foreign nationals. By requiring visas, countries can ensure that travelers comply with their laws and regulations.
