For stays less than than 90 days, US citizens do not need a visa for tourist or business travel to this country, but a valid US Passport is required.
Any US citizen who wishes to travel to Liechtenstein for any purpose other than tourism or business negotiations (e.g. work, study, adoption, immigration, or stays longer than 90 days stipulated in the entry requirements) should contact our office.
Traveling to Liechtenstein
Liechtenstein does not issue its own visas. As there are no border controls between Liechtenstein and Switzerland, without exception the same visa requirements apply to travelers to Liechtenstein as they do to travelers to Switzerland. Please contact the Swiss representation in your US consular district for further information.
