In my dissertation, I compare how a supranational religious institution, the Catholic Church, has influenced the adaptation paths of Haitian immigrants in three contexts—Miami, Montreal and Paris—with different immigration policies, norms about welcoming immigrants, and religious landscapes. My analysis triangulates quantitative data from the American, Canadian and French census and immigration statistics with 14 months of ethnographic work in the three sites, including over 100 interviews. The results suggest that in Miami, where Haitians’ context of reception was most negative, the Catholic Church has had the greatest influence in opening up paths of selective acculturation for Haitians. In Montreal, the Catholic Church initially organized the Haitian community, but over time, their social justice programs and ethnic ministry have declined in significance. In Paris, the Church provided some seed resources for Haitian community organizing and ethnic ministry, but this aid is modest compared to Miami and Montreal. My analysis underscores how cultural, religious, and political contexts intersect to shape how immigrants build communities and adapt to their host societies. I also use ethnographic data to show how individuals’ subjective religious experiences allow them to symbolically create a space for themselves in the host society. In all three cities, community religious experiences lead to the creation of associations to promote the integration of Haitians.
