Abstract

This study examines the linguistic challenges encountered by international students in Thai higher education, with a particular focus on how these challenges impact their academic success and psychological well-being. A survey of 204 international students revealed that 72% experience significant anxiety during English interactions, which leads to social isolation and a diminished sense of belonging, as 68% struggle to connect with peers. The research identifies that language barriers hinder participation in extracurricular activities, contributing to feelings of alienation. Conversely, effective language support systems were found to enhance academic outcomes and reduce anxiety among students, with 78% reporting improved comprehension and 70% feeling more secure in communication. This study emphasizes the importance of comprehensive language support in facilitating the integration process, mitigating psychological distress, and fostering social connections, ultimately enhancing the overall experience of international students in Thailand. Recommendations for targeted interventions and support mechanisms are proposed to enhance linguistic competence and foster a more inclusive academic environment.
