As the site notes, in 2017 a total of 29,257 USV applications were recorded at Slovenian embassies and consulates, and of these 2,481, or just over 11% were rejected. This compares to 1,732 rejected applications in 2016, thus showing an increase of 43% in such visas that were denied.
The centre of these rejections was the consulate in Kosovo, the location with the second greatest number of applications filed at a Slovenian office. In 2017 a total of 4,440 Kosovo citizens tried to get a USV at Slovenia’s consulate in Prishtina. Of these, 1,139 were denied, or 30.4%, accounting for over than half (54%) of all such denials recorded at Slovenian offices around the world.
Kosovo also saw the highest number of Limited Territorial Validity (LTV) visas being issued for Slovenia, at 3,045. An LTV visa allows you to travel only in the Schengen state that has issued the visa.
