This article focuses on the diasporas' role in fostering Global Citizenship Education (GCE) and provides a basis for understanding how diaspora organizations educate themselves to defend their rights in everyday life. I argue that diaspora organizations are potential agents that foster GCE to defend rights in a hostile environment against people in motion. From the GCE-driven critical perspective, this article offers an interdisciplinary dialogue between Diaspora Studies (International Relations), Sociology of Education, and Sociology of Collective Action to identify the practice of GCE at the New American Diaspora in Mexico City. The article is oriented to discussing the non-state actors' agency in promoting GCE outside the walls of schools and classrooms. With a qualitative approach (case study), through an American/Mexican organization, I offer empirical evidence through the lens of GCE: The Others Dreams in Action (ODA) and its cultural space, namely the Poch@ House.
