The increasing turnover rate among expatriate teachers in Indonesia's international and intercultural schools underscores ongoing challenges in retention and the necessity for research on organizational commitment. Thus, this study aims to explore the direct and indirect effects of job security, intercultural teaching competence, career satisfaction, and organizational commitment of expatriate teachers in Surabaya, utilizing a quantitative and explanatory approach. The collected data was analyzed using Partial Least Squares Structural Equation Modeling and involved 125 expatriate teachers from various schools in Surabaya. Findings indicated significant direct effects: both job security and intercultural teaching competence positively influenced career satisfaction, while job security also contributed to organizational commitment. Although intercultural teaching competence did not have a direct effect on organizational commitment, career satisfaction emerged as a notable predictor of organizational commitment. Furthermore, the analysis of indirect effects highlighted that job security and intercultural teaching competence significantly influence organizational commitment through career satisfaction, showcasing its crucial mediating role. The results suggest that enhancing job security and intercultural teaching competence is necessary for improving expatriate teachers’ career satisfaction and organizational commitment. This can reduce turnover rates and enhance international and intercultural education managerial policies.
