Visas are not required if you hold a passport for the UK, Ireland, the USA, Canada, Australia, New Zealand or South Africa, whether visiting as a tourist or on business. Citizens of the EU, Norwegians and Icelanders may also enter Switzerland without a visa. A maximum three-month stay applies, although passports are rarely stamped. Citizens of several African, Asian and Arab countries, plus Eastern European and Balkan states, require visas. A current squabble with Libya means visas for citizens of that country are not being issued by Switzerland. For up-to-date details on visa requirements, go to the Swiss Federal Office for Migration (www.eda.admin.ch) and click 'Services'.
In Switzerland, carry your passport at all times and guard it carefully. Swiss citizens are required always to carry personal identification, so you will also need to be able to identify yourself at any time.
