This article presents the institutional and historical context, methods, findings, and action-consequences of 'Our HMoob American College Paj Ntaub,' a qualitative, student-led Participatory Action Research (PAR) project documenting the sociocultural and institutional factors that influence HMoob American college students' experiences at the University of Wisconsin-Madison. Drawing on concepts from Asian Critical Race Theory (AsianCrit), we identify sociocultural and institutional processes that misrepresent and erase HMoob American experiences, producing a profound and troubling experience of institutional invisibility which has serious consequences for students' wellbeing and educational attainment. However, we also document that student-led PAR research can be an effective means of enacting what we term 'counter-invisibility work,' by producing compelling counter-narratives that expand social networks for activism, outreach, and policy enactment.
