Pour une Planète sans Frontières (PUPSF) is a non-profit organization composed of a hundred volunteers, lawyer-researchers, translators and interpreters, who are committed to defending the right to understand and be understood. The association aims to enable all foreigners, whatever their origin or level of resources, to defend their rights on French territory. Over the last few years, PUPSF has set up various legal, geopolitical and linguistic assistance services in conjunction with its partners. We carry out our actions throughout France by developing various projects: "An interpreter for all", "An interpreter at school", "A jurist linguist for all", "Geopolitik" and "the toolbox for all".
