Why some immigrants return and most students want to leave: towards a contextual analysis of return motives, mobility prospects and non-return: the example of Morocco.

Summary The subject of the thesis deals with the theme of Moroccan migration in three dimensions. First, return migration is examined through the prism of the motives that lead the emigrant to return to his country of origin. Then, from a post-migration perspective, his resettlement and the conditions necessary for his integration in his new/old society of birth. Finally, the last section is devoted to the intentions of international mobility and non-return among Moroccan students. The mobility of students from the South to the North is often seen as a precursor to a sustainable settlement. The migration policies of receiving countries have profoundly shaped the profile of immigration candidates during the second half of the 20th century and during the first decade of the 21st century. From a demand based on a young, healthy and above all cheap labor force, the profile of immigration candidates has evolved towards another one, in this case, more qualified or a fortiori likely to become so.
