Different rules apply for entry to Switzerland. In principle, a distinction is made between nationals of EU/EFTA countries and third-country nationals. An overview of ID and visa provisions according to nationality can be found on the webpage of the State Secretariat for Migration SEM.
Third-country nationals who require a visa to study in Switzerland must apply in person for a student visa at the relevant Swiss consulate abroad (embassy or consulate-general). Visa applications should be made at least 3 months before the envisaged entry to Switzerland.
International students from countries that do not require a visa to study (stays of more than 90 days) may apply for their residence permit directly at their place of residence in Switzerland after entering the country.
