Study abroad is not an easy decision for international students who cannot manage the local language and academic courses, particularly nursing students who need to communicate with their patients in clinical environments. This study aims to explore international nursing students' experiences of pre-sessional language prerequisite courses in South Korea. Three directions were categorised, including what are the motivations and reasons to come to South Korea, how do the international nursing students describe their Korean language courses as the prerequisite for their nursing programme at one of the South Korean universities, and why did the participants select South Korea as their destination for the nursing programme. Based on the Social Cognitive Career and Motivation Theory and a qualitative design, the researcher invited 12 participants who are taking the pre-sessional language courses before the nursing programme commencement. The results indicated that personal considerations, interest in career development, and financial considerations are three of the key elements. The outcomes of this study allowed the nursing school leaders and government agencies to polish their current curriculum plans, international students' recruitment strategies, and post-study career developments for international nursing students in the East Asian region.
