This qualitative study explores the anticipated repercussions of the Brexit Referendum to the internationalization of UK universities. The referendum approved the UK leaving the European Union. This process of leaving has become known as "Brexit." The UK has been part of the European Union for over 40 years and this membership fostered the international exchange of students and academics. University campuses across the UK have experienced significant internationalization. The study explored emergent concerns on the challenges that higher education institutions would confront as the process of Brexit continues to develop. The research draws on testimony given to the Education Committee of the House of Commons, government documents, media reports, fieldwork and interviews of UK academics. Findings are presented thematically as a narrative and include concerns about potential reduction of international students and faculty, decrease in international research collaboration and research funding, and the possible negative impact on campus and community climate.
