[citation needed] Liechtenstein is the only microstate (not counting Iceland by population) that is part of the EEA.

All EFTA states bar Switzerland are in the EEA, which gives them access to the EU single market.

[11] Before this, Switzerland shared an open border with Liechtenstein and was already a full Schengen Area member.

However, ratification was initially delayed at the behest of Sweden and Germany who felt that Liechtenstein had not done enough to fight tax evasion;[13][14] the Council of Ministers eventually consented to the ratification of the protocol on 7 March 2011,[15] with the protocol entering into force a month later.

Although a member of the European Economic Area Liechtenstein does not adhere to the free movement of labour unlike every other member of the European Union and EFTA because its small size and relative prosperity mean that it is vulnerable to high immigration.
