This study explored the influence institutional cultures and structures have on a university's internationalization strategy. It also accounted for the roles external forces, such as government policies and geopolitics, play in shaping internationalization strategies. The comparative case study between the United States, England, and Sweden were situated within the contextual framework of comprehensive internationalization developed by the American Council on Education (ACE) and German Academic Exchange Service (DAAD). Applying neoinstitutionalist theory of isomorphism, the case study revealed three typologies of internationalization strategies: idealist, realist, and pragmatist. The study's findings provide scholars and practitioners with new tools and insights to right-size an institution's internationalization strategy based on internal structures and cultures, as well as its external environment.
