Yes. Because the US is not included on the list of countries free from Tanzania visa requirements, US nationals are required to obtain a visa before traveling to Tanzania. The Tanzania eVisa is an electronic travel document that allows citizens from eligible countries to travel to and enjoy Tanzania (including Zanzibar). Currently, there are more than 150 countries that can take advantage of the Tanzania electronic visa system, including the US.
This type of e-Visa is valid for travel and leisure activities like vacations in Tanzania or Zanzibar or casual visits to family and friends. Travelers who wish to transit through Tanzania en route to other countries can also apply for a Transit visa. Fortunately, US passport holders can now apply for a Tanzania visa online which helps them save time and money compared to going to an Embassy or the Consulate. There are 04 different types of Tanzania eVisa available to US citizens: tourist eVisa - single entry or multiple entries, transit eVisa, and business eVisa. Each type serves a different purpose with a specific staying time allowed; thus, US nationals should choose the one that best suits their travel plans. With an eVisa, they can remain in Tanzania for up to 03 months.
