This paper explores the outcomes of a virtual tandem Language Exchange Program (LEP) designed to connect learners of L2 Vietnamese from the US and Italy with L2 English and Italian learners from Vietnam. Conducted over a 15-week period with 6 synchronous meetings for the Vietnam-US exchange and 8 meetings for the Vietnam-Italy exchange, the program engaged 20 participants in virtual conversations, enabling them to practice their target languages. Findings from participant surveys and reflections suggest that well-designed LEPs can effectively support the development of Communication, Cultures, and Communities competencies. However, the study also identifies challenges related to proficiency imbalances, technical issues, and scheduling difficulties. The significance of these findings lies in their implications for teaching Vietnamese as a second language on a global scale. The study demonstrates that LEPs can bridge the gap between formal classroom learning and authentic language use, providing learners with practical, culturally immersive experiences that are often lacking in traditional language programs. By addressing logistical and pedagogical challenges, future LEPs can be further refined to create richer, more flexible learning environments that better serve the diverse needs of language learners worldwide.
