Referral rule
Do Afghan citizens need referral visa approval?
Afghan passport holders are listed in the Tanzania referral visa category, so they should treat the application as a prior-approval case rather than a normal tourist eVisa.
For Afghan 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.
