Travellers to Tanzania require a valid Visa each time they enter the Republic. The granting of a Tanzanian Visa is, in effect, only a form of pre-entry clearance. It does not guarantee permission to enter Tanzania. The Immigration Officer reserves the right to grant or deny admission. Visa holders are subject to normal Immigration control at the port of entry. They should therefore carry with them, for possible presentation to Immigration officers, the documents submitted with their applications.

In principle, all visitors, except those with no visa requirement as listed below, must obtain a visa prior to entry to Tanzania. Visas can be obtained at any Diplomatic or Consulate Mission of the United Republic of Tanzania abroad, normally within one business day. Visitors are urged to do so to avoid any possible inconvenience at point of entry in Tanzania.

It is possible, however, to obtain a tourist's visa for a single entry at any one of the following four main entry points to Tanzania, subject to the fulfilment of all immigration and health requirements:

Dar es Salaam International Airport
Zanzibar International Airport
Kilimanjaro International Airport (KIA)
Namanga Entry Point (Tanzania-Kenya boarder point)

(This facility is generally for those who could not apply for a visa from a Tanzania Mission abroad) For all other entry points in Tanzania, visitors must hold valid visa prior to arrival.

Countries which are not required to apply for Visa

As of May 2019, citizens from 69 countries can enter Tanzania without a visa.

Note:

Possession of a Visa for United Republic of Tanzania does not provide automatic right of entry for the holder into the Country. The Immigration Officer at the port of entry may refuse entry to any person, if he is satisfied that such a person is unable to fulfil the immigration requirements or that such person's presence in the United Republic of Tanzania would be contrary to national interests or security.
