United Kingdom - Passport & Nationality - Asians in Tanzania (UK Nationality)
Because of how the Constitution of Tanzania determined how Citizenship was granted, Tanzanians with parents or grandparents born OUTSIDE of Tanzania (even in the different parts of Tanzania that made up modern day Tanzania) have a possibility of being granted one of the five forms of British Nationality. This is because of the protection offered to British Subjects born or resident in Tanzania and Zanzibar before Independence.
In particular, and because of the large numbers involved, Tanzanians with Indian ancestry (parents or grandparents born in India) have a higher likelihood of being granted automatic British Nationality.
STATUS OF TANZANIA (formerly Tanganyika and including Zanzibar)
