United Republic of Tanzania
Tanzania splits responsibilities between two authorities: the Immigration Department issues residence permits (Class A for investors and the self-employed, Class B for employment, Class C for students, retirees and others), while the Prime Minister's Office handles work permits. A Class B residence permit requires a work permit first. Permanent residence exists but is discretionary and granted only after long residence.
