A transit visa is a document that allows a traveler to pass through a country on their way to a destination. However, there are several other terms that can be used to describe this type of visa. These include stopover visa, connecting flight visa, layover visa, and through visa. Each of these words implies a different aspect of the transit experience, from the brief period of time spent in the country to the purpose of the travel. Regardless of the term used, a transit visa is necessary for anyone who needs to pass through a foreign country in order to reach their final destination.
