Documents necessary for travelling beyond the Schengen Area
It is possible to cross an external border only with a valid travel document or a different document enabling to cross it.
Slovak nationals may travel abroad only with a valid travel document, if not stated otherwise in an international treaty binding for the Slovak Republic. Slovak nationals younger than 5 years old may only travel abroad without their own travel document if they travel with their parents holding the travel document they are registered in.
Details on necessary documents required for an entry and stay by relevant third-country authorities are stated on the web pages of the Ministry of Foreign Affairs of the Slovak Republic.
