Ce The migration has often been studied through Moroccan emigrations to the Europe. It is recently that studies have focused on Morocco as a host country, especially for Sub-Saharan. Indeed, Morocco has tried through its new migration policy to create a favorable and warm welcome context for the sub-Saharan migrants. Through our article we seek to define the factors that influence settlement decision of sub-Saharan migrants in Morocco. we try to understand what differentiates sub-Saharan migrants who intend to settle permanently in the Kingdom of Morocco from those who take Morocco as a country of transition. In this sense, our article attempts to describe and explain the differences and specificities that may exist between migrants from different sub-Saharan countries in terms of the choice of Morocco as a country of residence. This is to detect the homogeneity or heterogeneity that may exist between different groups of sub-Saharan migrants in terms of socio-cultural and economic integration. To define factors of permanent residence decision in Morocco, we conducted a survey with a sample containing 200 individuals. We concluded that several variables may explain the Sub-Saharan residence decision in Morocco (age, gender, educational level, membership in ethnic association)
