A Schengen Visa is a document that allows travelers to enter the Schengen Zone and stay for a total of 90 days in 180 days. It encourages short-term stays and is applicable for purposes including tourism, business visits, attending events, visiting friends or family, or medical treatment. This makes it possible for travelers to cross international borders within the Schengen Zone without undergoing border checks or encountering passport control, making travel significantly more efficient.
There are 29 countries within Europe that make up a zone called the Schengen Zone. These 29 countries have abolished passport controls at their mutual borders. The primary purpose of this is to streamline the process for travelers, making it possible for them to visit multiple countries in Europe without the hassle of obtaining separate visas for each country. This not only simplifies travel logistics but also facilitates travel across the region.
