All third-country nationals, regardless of their visa obligation status, who wish to enter the Schengen Area through Switzerland must be in possession of a travel document that meets both of the following two requirements:
- The validity of the travel document must extend at least three months after the intended date of departure from the Schengen Area; and
- the travel document must have been issued within the previous 10 years.
The date of issue of the travel document shall be the determining factor, notwithstanding any decision by the authorities to extend the period of validity of the travel document.
Please find travel documents entitling the holder to cross the external borders in Annex 2 of the Visa Guidelines:
