Ogeste Gelevasi sits in front of his humble house, looking out over fields of cassava and tobacco with a wide smile of contentment. He feels at home here in western Tanzania after almost 40 years as a refugee from neighbouring Burundi. For Ogeste, the country he fled aged two is a foreign country; that's why he, like an estimated 165,000 of the remaining so-called 1972 Burundians living in Mishamo and two other "old settlements," have decided to accept a landmark offer by the government to settle in Tanzania and apply for citizenship.
