Abstract: Expatriate-Repatriate Management (ERM) is increasingly considered an important branch of International Human Resource Management (HRM). With the rapid growth in the globalizing business environment, it is still an emerging field of research in the Sri Lankan context. This research paper is an attempt to find out some research gaps in the ERM process which are highly essential to address in the future empirical studies. The scope of the paper, thereby, was limited to empirical findings available in Sri Lanka and it resulted in identifying six gaps in the ERM process under the coverage of two theories namely, contingency theory, and social exchange theory. Empirical research findings of future research studies could fill these identified research gaps.
