Schengen visa holders
Bulgarian government took a decision on 25 January, 2012 that until Bulgaria’s full accession to the Schengen Area, the country will unilaterally apply visa-free regulations for holders of valid Schengen visas. According to the decision, holders of valid Schengen visas may enter and stay in Bulgaria for a period of up to three months within each six-month period from the date of the first entry in this country without having a Bulgarian visa (with effect from 31 January, 2012). Holders of single-entry Schengen visas and those whose Schengen visas have been utilized completely are, however, not being allowed to enter Bulgaria.
