All visitors to Ethiopia require a visa. However, at Bole International Airport in Addis Ababa, a tourist Visa on Arrival (VOA) is available to leisure visitors from the USA, Canada, Mexico, Brazil, New Zealand, Australia, South Africa, China, Japan, Korea, Israel, Russia, the UK and all other European Union nations. A one-month tourist VOA costs US$50 and three months costs US$70. Multiple-entry visas are not currently available on arrival, so should be obtained in advance at an embassy. Please note that visa on arrival is not available to visitors entering by land borders. Business travellers, consultants and professionals working for NGOs need a Business Visa. This should be obtained in advance from an Ethiopian Embassy. Visitors who have their residence in countries without an Ethiopian Embassy, or far from the capital where the Embassy is located, can get the support of the organisation they are working for in Ethiopia to provide them with a document issued by the Immigration Authority allowing them to get a one-month single-entry visa on arrival. Both tourist and business visas can be extended at the Immigration Authority offices located in Churchill Road, near the Post Office, in Addis Ababa.
