Unless communicated differently, you are in charge to get the right visa for your travel to Tanzania.
• Your passport needs to be valid for at least 6 months when you enter the country.
• From the day you receive your visa, you have 3 months to travel through Tanzania. From the day you enter the country, the visa is valid for 90 days. So pay attention to not request your visa too early.
UK residents can only apply for the visa online.
Request your visa on time, but not earlier than 3 months before your departure date.
