The Schengen Visa enables its holder to move around 27 European countries within the Schengen Area using one visa only. A single visa provides permission to stay for 90 days within any 180-day period. The number of Schengen countries you can visit depends on the particular visa type you receive (single, double or multiple entry). The application process requires you to submit your documents to either the main destination consulate or the first entry country. The visa serves exclusively for tourism and business travel as well as family visits and it prohibits employment.
