A-type visa or airport transit visa is an individual single-entry, double-entry or multiple-entry transit visa enabling a foreign national to cross the airport transit zone once, two times or an unlimited number of times, respectively.
The A-type airport transit visa entitles the holder only to stay in the international transit area of the airport (it does not entitle the holder to enter Schengen territory or to leave the transit area of the airport). The maximum term of validity of an airport transit visa is six months.
Airport transit visa is required for citizens of Afghanistan, Bangladesh, Democratic Republic of Congo, Eritrea, Ethiopia, Ghana, Iran, Iraq, Nigeria, Pakistan, Somalia, Sri Lanka or foreigners holding passports issued by the aforementioned countries.
