OBS_VALUE: The aviation crew members (the flight crew, cabin crew, engineering and technical staff providing technical support of flights, and personnel ensuring the safety of the aircraft in flight) do not require visas in the Republic of Kazakhstan because Kazakhstan is a member of the International Civil Aviation Organization. Therefore, while on duty, air-crew members receive crew member's certificate, which serves as a pass in order to enter Kazakhstan. In case of absence of the ICAO certificate, obtaining a B5 visa will be mandatory. A single entry B5 Visa for crew members of air, sea, river vessels and train crews is issued for up to 90 days, multiple entry visa - for up to 1 year.
