All applicants are requested to apply through the Embassies of the European Member States present in Khartoum.

The Schengen visa can allow you to enter an area comprising of 26 European countries that have officially abolished all passport and all other types of border control at their mutual borders. The area mostly functions as a single jurisdiction for international travel purposes, with a common visa policy. The area is named after the 1985 Schengen Agreement signed in Schengen, Luxembourg.
