Requirements for entering Liechtenstein
Switzerland and Liechtenstein share the same entry requirements. The provisions concerning persons requiring visas are identical (see Ordinance of 14 January 1998 on the Entry and Registration of Foreign Nationals, SR 142.211). In principle, this ordinance requires a passport to enter the country, subject to the provisions of bilateral or multilateral agreements.
Individuals requiring a visa may submit an application to the Swiss representation in their country of residence. The Swiss authorities decide on the request.
