Applications for visas can sometimes be made via the online visa system. If you cannot apply for a visa online, you can submit a visa application at a Swiss embassy or consulate in the country of your legal residence.
You can download and fill in the application form for a Schengen visa.
If you intend to visit more than one country in the Schengen area, the embassy or consulate of the country where you will spend the longest time is competent. If you intend to visit several countries in the Schengen area for equal lengths of time, you should apply at the embassy or consulate of the country through which you will first enter the Schengen area. If Switzerland is the only, the main, or the first country you will visit in the Schengen area, as explained above, you must apply for your visa online or at a Swiss embassy or consulate.
