This study investigates the cultural and language barriers faced by Lao students at Vietnamese universities of education and proposes solutions for enhancing their academic and social integration. We analyzed the experiences of 624 Lao students across eight major universities in Vietnam through online surveys and in-depth interviews employing a mixed-methods approach. This study revealed that Lao students face significant language and cultural challenges that manifest in difficulties with Vietnamese language proficiency and adaptation to the academic culture in Vietnam. Despite these challenges, support from the Vietnamese student and teacher communities plays a crucial role in their adaptation process. The research underscores the need for enhanced teaching methodologies and the development of robust support systems for international students highlighting the pivotal role of language and cultural support in improving the educational experiences of Lao students. Addressing the language and cultural barriers faced by Lao students is essential for fostering their successful integration and participation in the Vietnamese educational system. Enhanced language support and culturally sensitive pedagogical strategies are recommended to enhance the academic success and social integration of these students, thereby contributing to a more inclusive educational environment.
