Hong Kong (SAR China) to Guinea-Bissau visa requirements

HK passport holders need a visa for Guinea-Bissau. The standard route for a short tourist trip is a visa on arrival, valid for stays of up to 90 days. An online pre-enrollment (eVisa) is also available, and obtaining a Migration Office authorization letter in advance is strongly recommended to avoid problems at the port of entry. Guinea-Bissau is a West African country and is not part of the Schengen area, so ETIAS and the Schengen 90/180 rule do not apply. Hong Kong is not on Guinea-Bissau's visa-exempt list (which covers ECOWAS member states and diplomatic/service passport holders of Portuguese-speaking countries), so HK SAR ordinary passport holders require a visa. Travelers who are not visa-exempt may obtain a visa on arrival valid for a maximum stay of 90 days, or apply in advance through a consulate or the online pre-enrollment (eVisa) system. In practice, arriving travelers are expected to carry a printed authorization letter from Guinea-Bissau's Migration Office (Servico de Migracao e Fronteiras), arranged in advance through a local contact or sponsor; without it, visa-on-arrival issuance can be refused or delayed. A passport valid for at least six months beyond entry and at least one blank page is required. Because consular infrastructure for Guinea-Bissau is limited and policies are not always consistently published, the conservative recommendation is to pre-arrange the authorization letter (and, where possible, an eVisa) before travel rather than relying solely on showing up at Osvaldo Vieira International Airport in Bissau.
