Queer Aspiration, Belonging, and Emotional Borders in Transnational Education: Floating in the Borderfoam traces the emotional and everyday worlds of queer Vietnamese students moving through transnational education across Southeast Asia. Foregrounding fragments, pauses, and ordinary scenes over success stories, the book introduces borderfoam to describe life amid overlapping educational, legal, familial, and digital borders that never fully settle. Drawing on narrative interviews, autoethnography, and poetic reflection, it follows queer students as they navigate visas, classrooms, family expectations, and online platforms, managing disclosure, aspiration, and survival while mobility reshapes emotional life and belonging. Queer Aspiration, Belonging, and Emotional Borders in Transnational Education: Floating in the Borderfoam will interest scholars, graduate students, and practitioners in international and transnational education, gender and sexuality studies, human geography, migration studies, and qualitative research.
