In 1919, at the request of the Government of Liechtenstein, Switzerland agreed to look after the interests of Liechtenstein and of Liechtenstein citizens abroad. This means that in all countries where Liechtenstein does not have a mission, citizens of Liechtenstein can use the services of the local Swiss mission in consular matters. In the U.S., Liechtenstein is officially represented by its Embassy in Washington, D.C. and it's Mission to the U.N. in New York:
