This mixed methods study explored co-curricular student leadership development programs that included intercultural learning and were designed for international students studying at higher education institutions in the United States. The study aimed to better understand: (a) common program characteristics; (b) program administrator perceptions; and (c) the international student experience. Data was collected in a two-phase explanatory sequential design, involving surveys and semi-structured interviews. Six main content areas across all programs were identified: (a) diversity, equity, and inclusion (DEI); (b) global engagement; (c) intercultural learning; (d) leadership development; (e) personal and professional development; and (f) supporting the international community. Administrators generally perceived leadership programs as positively contributing to the international student experience, citing an increase in student sense of belonging, self-confidence, and motivation to seek out other leadership opportunities. International student respondents corroborated the administrators' perspectives, unanimously indicating that the program contributed to their sense of belonging. Students also noted increased self-confidence and gains in leadership, intercultural, and interpersonal knowledge and skills. Findings highlight the value of co-curricular programs to the international student experience, particularly in cultivating a sense of belonging. In order to better support international students, campuses should dedicate resources to support these types of programs.
