A Brief History of Senior International Officers on U.S. Higher Education Campuses captures the diversity of SIO roles, their varied accomplishments and challenges, and the tools and strategies needed to make them most successful. Based on survey data and select interviews with 200 SIOs from across the United States, our findings reflect the complexities of SIO responsibilities and priorities. Collected during the COVID-19 pandemic, our research focuses on strategic factors and considerations for success as SIOs navigate the path forward. We hope that the findings from our research contribute to an important and wider discussion about the SIO role on U.S. higher education campuses and its need to continue to advocate for internationalization and academic exchange.
