For the entry in South Korea and for tourist and business purposes up to a duration of stay of 3 months citizens of Switzerland and Liechtenstein do not require a visa.
A visa is necessary compelling for longer stays, for the employment or for non-privileged citizens. For this a coloured passport photo is required in the format 35 x 45 mm which may not be older than 6 months. The passport photo can be adapted with our passport photo generator quickly and simply to the right size. Up to a few exceptions the same biometric regulations apply as they are also valid in Switzerland for all identity card documents.
You find further information about the application process on the website of the South Korean embassy in Bern.
