Despite an increase in migrant entrepreneurship research in recent years, the current literature predominantly emphasizes the influence of structural changes, often overlooking the agency of migrant entrepreneurs in overcoming marginalization. Drawing on identity work theory, this paper explores the findings gathered from interviews with migrant entrepreneurs in Australia to address this knowledge gap. The findings offer an alternative perspective on how migrant entrepreneurs navigate different types of identity work to overcome structural, relational and sociocultural marginalization. They engage in identity construction by affirming their personal identity and connecting with their social identity. Migrant entrepreneurs then mobilize their identities by signaling their professional and entrepreneurial identities and personifying their entrepreneurial role. Finally, migrant entrepreneurs also recategorize their identities by adopting identity fluidity and embracing hybrid identities. These insights have significant implications for research into the agency of migrant entrepreneurs and for identifying ways to overcome their marginalization.
