This study investigates the Korean language learning needs of international students enrolled in English-track programs at universities in Korea, with the goal of suggesting improvements in both instruction and the broader educational environment. A survey of 329 English-track international students at a university in Busan was conducted, examining their needs in four areas: learning environment, Korean language courses, instructors, and learners. To complement the quantitative analysis, in-depth interviews were carried out with 10 selected participants. Findings reveal that students expressed the greatest needs in relation to the learning environment and learner-related factors. Specifically, they emphasized the importance of increased opportunities for interaction with Korean students, the establishment of student clubs and common spaces, courses designed for the Test of Proficiency in Korean (TOPIK), and classes emphasizing practical speaking skills. By contrast, satisfaction with instructors was generally high. Correlation analysis showed the strongest relationship between the learning environment and Korean language courses, underscoring the necessity of improving the overall educational environment to enhance course satisfaction. This study offers practical implications for tailoring Korean language instruction to the needs of English-track international students and recommends further research across diverse regions and language backgrounds.
