Can I enter and leave Schengen countries at will with a Schengen tourist visa issued by the Swiss Embassy during the visa period?

Switzerland is a Schengen country. During the validity of your Swiss visa, you can enter and leave other Schengen countries at will.

Swiss tourist visa time control is very strict, and the validity of the visa issued is calculated according to the travel plan submitted when you apply for a tourist visa.

If you don't leave the country after the time limit, the customs will treat it as illegal residence when checking the documents.
