What Is a Visa and Why Is It Required?

A visa acts as a conditional authorization granted by a country to a foreigner, allowing them to enter, remain within, or leave that country. The necessity of a visa depends on visa policies by country, usually shaped by bilateral agreements. For example, European Union citizens can travel freely among member states without requiring a visa, but the same does not apply to non-EU citizens.
