This study seeks to show how decolonial thinking, from the perspective of communication, built from the reality of Brazil and Latin America, serves to analyze an experience of organizing emigrants' alternative political struggles. For this, it is proposed a content analyze that shows how the themes communication, information and culture were constituted in four official documents of the group that formalize needs and record proposals for improving the lives of Brazilian emigrants abroad. The results point to ideas and concrete actions that allow us to visualize that, in the face of a colonial relationship, the experience from the global South contributes to another possible, emancipatory and renewing reality.
