<p>Recent research highlights the link between migration and health within the social determinants of health (SDH) framework. However, much of this work focuses on Global South to Global North migration, leaving other migration patterns underexplored. This study examines access to healthcare services among international students in Türkiye in the context of South-South mobility, and draws attention to the role of migration direction in understanding migration as an SDH. Based on 25 in-depth interviews, the study provides empirical insights into how South–South migration is experienced in the Turkish context, particularly in relation to access to healthcare services. The findings offer insight into how key SDH factors—such as health-seeking behaviors and linguistic and cultural differences—operate in a South–South context, while also emphasizing the need for research to assess whether these patterns can be generalized beyond this context. By highlighting the relevance of migration direction, this study contributes to the broader discussion of migration within the SDH framework and points to the need for comparative research on how different migration directions shape health equity and outcomes.</p>
