Nationals of many countries can travel to Hong Kong without a visa. However, for other individuals a visa may be required. The Hong Kong immigration department has special arrangements for Mainland Chinese passport holders as well as those from Chinese Taipei.
The APAO Secretariat encourages anyone who requires a visa to enter Hong Kong to apply at their earliest convenience to avoid any last-minute delays or complications. Delegates who have registered for the APAO Congress can generate an invitation letter for visa application purposes after logging in to the Congress system.
