Seven thousand Bulgarian citizens have been barred from leaving the country for one year for having violated the laws of the countries they had visited or for using invalid foreign-travel documents, Colonel Stoyan Zahariev from the National Police Service Directorate announced. The Bulgarian Interior Ministry has not received an official enquiry from Oslo in connection with Bulgarian citizens of Roma descent, who have applied for asylum in Norway. The Border Police will further tighten border controls, and the Economic Police will check whether tour operator companies have solicited would-be emigrants to pose as their tourist customers for a profit`, he said. Bulgaria will fully cooperate in the readmission of the Bulgarians illegally residing in Norway, even if it will have to meet the expenses, because the situation is delicate, Zahariev asserted categorically. Between 350 and 500 Bulgarian citizens are presumed to be illegally staying in Norway. They might have been tempted by the hypothetical opportunity to get big salaries and to receive a job after arriving in the Nordic country, the Bulgarian Interior Ministry official assumes.
