Visit the consulate office of the Tanzanian Embassy nearest you (see Resources) and request a passport application if you wish to apply in person. Otherwise, download the application from the Embassy of Tanzania website (see Resources) to process your application by mail.
Provide proof of your Tanzanian nationality by presenting any of the following documents: original birth certificate, certificate of Tanzanian nationality, declaration of Tanzanian nationality or naturalization card.
Submit five copies of a color passport photo 35 mm by 45 mm in size, taken against a light blue background. They must be a frontal portrait of the face taken without any glasses or anything worn on the head. The photos must be taken no more than 30 days before your passport application is processed.
Verify any applicable passport fees. This will vary depending on the currency of your country and whether you require expedited processing. Send a self-addressed prepaid envelope to the Tanzanian Embassy, and they will send you the new passport within 3 weeks.
