While studies on immigrant enterprises are increasing, the smaller size and scale of such enterprises consisting of Immigrant Micro Enterprises (IMEs) in labour-intensive industries are still under-researched. This review paper provides an overview of scientific research consisting of journal articles on IMEs to understand the characteristics that influence innovation and business growth in the relevant industries. Findings are presented in a conceptual framework to set the precedence for future studies. IMEs experience additional difficulties than their native counterparts and those of larger sizes, including resource scarcity, language issues, lack of network, funding, government support, and local market knowledge. However, innovation in such enterprises is driven by the entrepreneurs' traits and characteristics, motivation, risk perception, non-economic capital, experience, and education level, impacting their business strategies and tool adaption. IMEs significantly contribute to the new home country, particularly rural regions, the local economy, and cultural diversity.
