Foreign nationals require a tourist visa to enter Tanzania. For this you must have at least six months validity remaining on your passport. This can be purchased easily at the airport on entry at a cost of $100 USD cash for American citizens and $50 USD for all others. You can apply for this in your home country; however, this is sometimes more expensive.
Please seek advice from your medical center or doctor’s surgery regarding vaccinations and malaria prophylaxis. You may be required to show a Yellow Fever Certificate at the airport when entering Tanzania. Please ensure that you have had this vaccination and remember to bring the certificate with you.
