All visitors are required to carry a passport that is valid for six months beyond the intended length of stay. There should be sufficient blank pages for entry stamps upon arrival. With a valid passport, one may obtain a visa either before arriving in Tanzania at the Tanzania Embassy abroad or at any port of entry staffed by immigration officials, such as an international airport.
Most travellers require tourist visas for entry into Tanzania.
Please ensure you have the correct amount in cash and in the correct currency with you upon arrival. Most airports have no ATM, but if they do you are likely to lose out with their exchange rate. In addition, immigration officials are unlikely to have change and if they do, it will be in Tanzanian shillings at an unfavourable rate.
