European societies are expressing growing concern about the consequences of migrant family reunification on their soil for the management of their borders and the success of the integration process. Many policy makers assume that most migrants intend to bring their relatives to Europe as soon as possible, and argue that it might be difficult for reunified migrants to integrate into their host societies. Our results concerning the process of reunification of Senegalese couples in France, Italy, or Spain strongly challenge this view. Using MAFE (Migration between Africa and Europe) data with a life event history approach, we show that (1) separation is often a long-lasting situation among Senegalese couples; (2) separated couples do not only reunify in Europe but also quite commonly in Senegal; (3) the couples who reunify in Europe tend to be those who adapt most readily to the European culture and economy.
