Referral rule
Do Guinea-Bissau citizens need referral visa approval?
Guinea-Bissau passport holders are included in Tanzania’s referral visa category and need prior approval before travel.
For Guinea-Bissau citizens, the Tanzania visa policy is not the same as the standard visitor route. Referral cases must be submitted online and should wait for approval before the traveler starts the journey. The traveler or host should also review the official referral-country list from time to time because Tanzania Immigration may update it.
