At a time of exacerbated globalization, education, and more generally training, is a key factor for our society, at the heart of territories challenged to renew themselves in the face of the emergence around the globe of new centers of economic and demographic gravity, with their own models. Training, and its link with working life, is a real challenge to face, in the near future, the technological, economic, political and environmental revolutions that we are already facing. Beyond what is called sandwich training or continuing vocational training in Higher Education, the current challenge is indeed around lifelong learning, old concept but whose forms always call for an actualization in modernity. At the heart of a small island territory like Corsica, this challenge is all the more crucial to take up as it foreshadows its attractiveness in a context of glocalisation (Mair, 1991) now durably anchored.In an ever-changing global environment, with moving landmarks, increasingly complex personal and professional lives, and where everything that seemed well compartmentalized yesterday faces increasing porosity, the purpose of this contribution is to explain that the international mobility of students apprentices, at the heart of the construction of a skills economy, is a major strategic issue for the development and structuring of a small territory such as Corsica.
