In this chapter, the author attempts to sketch the phenomenon of internationalization as manifested in the literature on academic mobility. Internationalization is commonly seen as a process contributing to the quality in higher education while academic mobility is often regarded as the most critical dimension of this process. By providing a review of the literature on internationalization and mobility, the chapter highlights rationales for inbound and outbound mobility for higher education systems and institutions in the European Higher Education Area (EHEA). It further portrays how Georgia -- a small country in the Caucasus and a member of EHEA responds to the global phenomenon employing several reforms, support schemes, and institutional initiatives. Lastly, reflecting on current trends and policies, the author attempts to map the prospects for internationalization of Georgian higher education. This chapter offers a promising area for comparative and international research on internationalization and contributes to the literature on academic mobility in Europe.
