What is it about?
Global health depends on researchers, clinicians, and students being able to meet, share knowledge, and build partnerships across borders. Yet visa barriers often prevent people—especially those from lower-income countries—from attending conferences, training programs, and other important professional opportunities. This article brings together evidence and real-world examples showing how these barriers can affect careers, collaboration, and whose expertise is represented in global health. It proposes a Global Mobility Equity Framework with four areas for action: holding meetings in more accessible locations, designing better in-person and online participation, making institutions responsible for supporting affected participants, and creating regional visa-support systems. The article also explains why virtual attendance is not a complete solution. Unequal internet access, difficult time zones, language barriers, and fewer opportunities to network can still limit meaningful participation. Universities, conference organizers, and funders therefore need to treat mobility equity as a shared responsibility rather than leaving individuals to navigate these barriers alone.

Why is it important?
Visa inequities in global health are increasingly recognized as structural barriers that shape who can attend conferences, access training, build professional networks, and influence decision-making. However, proposed solutions have remained scattered across academic articles, commentaries, and practical toolkits. This article is timely because it moves the discussion from identifying the problem to organizing a coordinated response. It introduces a Global Mobility Equity Framework that brings existing recommendations together across four connected areas: equitable conference locations, inclusive participation systems, institutional accountability, and distributed visa-support mechanisms. The framework provides universities, conference organizers, funders, and professional bodies with a practical structure for planning, budgeting, and evaluating mobility equity. By shifting responsibility away from affected individuals and toward institutions, the article could help make global health participation more representative, accessible, and effective.
Perspectives
I was drawn to this topic because global health depends on the movement of people, ideas, and expertise across borders, yet access to those opportunities is far from equal. Through conversations with colleagues and co-authors who have experienced visa applications, delays, and denials, I became increasingly aware that these barriers are not simply administrative inconveniences. They can shape careers, limit collaboration, and determine whose knowledge is present in the rooms where decisions are made. As a global health researcher based in Canada, I recognize that I do not face many of the same mobility restrictions discussed in this article. My co-authors have and do face these kinds of barriers to full participation. That meant writing it as a team required careful attention to the experiences and scholarship of those most directly affected, as well as reflection on the responsibilities of institutions and allies working from more privileged positions. My hope is that this publication encourages readers to move beyond acknowledging visa inequities and begin asking what their own universities, conferences, funders, and professional organizations can do differently. Meaningful change will require more than individual support; it will require mobility equity to become part of routine institutional planning, budgeting, and accountability.
