This article for reflection raises the concept of expanding citizenship. His claim is focused on answering the question: how does the citizen system expand in its relationship with the public administration, based on the decision reference in territorial contexts of the cities of Pereira (Colombia) and Santiago de Chile (Chile)? The reader will find four theoretical-methodological discussion aspects and results: 1) the citizen not in society, but with society; 2) the political system and the citizen as a psychic system; 3) the forms of the relationship between public administration/public citizens in the scenario of the cities of Santiago de Chile (Chile) and Pereira (Colombia); and 4) extension/non-application of the citizen, as a problem based on extension/non-application, by way of conclusions.
