A government decree which entered into force on Tuesday 17 March prohibits foreign citizens from entering Hungary. From today, the travel documents of all arriving passengers are checked at Budapest Airport. Following this inspection, only Hungarian citizens and foreign citizens arriving from the countries of the EEA who are entitled to permanent residence are permitted to enter Hungary. All other foreign citizens are turned away by the authorities, and they must wait in the designated transit area until departure.
Budapest Airport is not closing; it will continue to welcome and launch flights. However, from Tuesday, only Hungarian citizens and foreign citizens arriving from the countries of the European Economic Area (EU member states, Switzerland and Norway) who are entitled to permanent residence, and attest this right with a permanent residence card, can enter Hungary. Such foreign citizens are treated the same way as Hungarian citizens.
Anyone, Hungarians and foreigners alike, are free to depart from the airport in the coming days.
The Airport Police Directorate checks the travel documents of the passengers of all flights at the border crossing point. In the case of families traveling together, if at least one of the parties is a Hungarian citizen, the foreign family member (child, parent, grandparent, husband or wife) is permitted to enter Hungary.
The requirement that Hungarian citizens arriving home from South Korea, Iran, Israel, China and Italy must undergo mandatory medical screening upon entry to the country remains in force.
Foreign citizens who are not permitted to enter Hungary must wait in the designated transit area until departure. Budapest Airport provides blankets, food, mineral water and, upon request, face masks for such passengers waiting in the transit area.
Together with the Airport Police Directorate, Budapest Airport is prepared to implement border controls. To ensure a seamless process, all flights will arrive at Terminal 2B going forward, where the inspection of travel documents takes place.
