International students undergo the same admission procedure as Swiss citizens: citizens of the Principality of Liechtenstein, acknowledged refugees, foreigners who themselves or whose parents have been in possession of a Swiss work permit during the last 5 years or who are holders of a federal or federally recognized maturity certificate and children of persons with diplomatic status in Switzerland. Foreign students should also be aware that they will be asked to pay somewhat higher fees should they be accepted on a course. They must therefore be able to prove that they have the financial means to pay both the fees and their living costs. It is no longer possible to obtain working permits, even for the holiday periods.
