Using quantitative data and ethnographic fieldwork carried out in Johannesburg and Maputo between 2005 and 2007, this article explores the meaning of city life for Southern Mozambican migrants in Johannesburg. First, I analyze the trajectories of migrants in Maputo and Johannesburg, before and after migration to South Africa. Second, I propose an explanation of the absence of political organization and the weakness of social links among Mozambican migrants, probably the major characteristic that distinguishes them from other African migrants in Johannesburg. Third, I focus on Mozambicans' everyday life in Johannesburg to illustrate the nature and extent of adaptation and transformation within the city. In focusing on differences linked to workplace and residence, I show how a foreigner moves from being a total outsider to becoming part of the metropolis by learning to cope with the city, establishing good relationships with his neighbors, and building a minimal level of trust with his work mates.
