A transit visa is a short-term visa that allows travelers to pass through a country on their way to another country. Transit visas are typically valid for a few days or weeks, and they allow travelers to stay in the country for a limited amount of time.
There are many reasons why travelers might need to apply for a transit visa. For example, travelers might need a transit visa if they have a layover in a country for more than a few hours, or if they need to change planes in a country. Transit visas can also be required for travelers who are traveling to a country that has strict visa requirements.
