Citizens of Uruguay do not need a visa for leisure stays of up to ninety days in countries that are part of the Schengen area. However, border officials in EU countries may ask for supporting documentation for entry into the country, such as a letter of invitation or proof of accommodation, medical insurance documentation or a return ticket.
To find out what the exact requirements are, contact the local consular services of the country to which you wish to travel.
Conditions of entry to the United Kingdom and Ireland are governed by their own national legislation and differ from the EU rules.
Uruguayan legal citizens holding Uruguayan passports stating that they have a third-country nationality who wish to travel to Schengen area countries or European Union countries that already apply the Schengen visa code (Romania, Bulgaria, Croatia and Cyprus), must comply with the requirements corresponding to their nationality of origin. Therefore, in case of having the nationality of a country included in the list of third countries whose nationals are subject to Schengen visa requirements, they will have to process the required visa at the relevant Consulate.
