Citizenship of the European Union Because Slovenia forms part of the European Union, Slovenian citizens are also citizens of the European Union under European Union law and thus enjoy rights of free movement and have the right to vote in elections for the European Parliament. When in a non-EU country where there is no Slovenian embassy, Slovenian citizens have the right to get consular protection from the embassy of any other EU country present in that country. Slovenian citizens can live and work in any country within the EU as a result of the right of free movement and residence granted in Article 21 of the EU Treaty. Travel freedom of Slovenian citizens Visa requirements for Slovenian citizens are administrative entry restrictions by the authorities of other states placed on citizens of Slovenia. As of January 2019, Slovenian citizens had visa-free or visa-on-arrival access to 180 countries and territories, ranking the Slovenian passport 11th in the world according to the Visa Restrictions Index. In 2017, the Slovenian nationality is ranked seventeenth in Nationality Index (QNI). This index differs from the Visa Restrictions Index, which focuses on external factors including travel freedom. The QNI considers, in addition, to travel freedom on internal factors such as peace & stability, economic strength, and human development as well.
