International academic mobility is an aspect of internationalization that is changing rapidly in terms of volume, scope, and impact. Although much of the attention and research on mobility has focused on undergraduate students participating in short-term study abroad, internships, and exchange experiences, the new push to develop international research partnerships and networks has led to the recognition of the importance and benefits of doctoral student mobility. The purpose of this article is to provide a current picture of the international mobility--both full-degree and short-term research and academic work abroad--of Canadian students in social sciences and humanities (SSH). The analysis focuses on the profile of internationally active SSH doctoral students, and the rationales that drive academic mobility, the factors that help or hinder it, and the types of scholarships available to support it.
