PurposeQualified immigrants (QIs) and their work experiences have been studied using a wide variety of theoretical approaches with divergent characteristics. This paper reviews theoretical progress and proposes directions for future research and practice.Design/methodology/approachUsing relevant keywords, articles indexed by Web of Science in management, business, industrial relations and applied psychology were systematically searched for and analysed. In total, 60 theoretical articles published during 2008–2018 were included. The theoretical progress and future theoretical and practical challenges were organised based on the notions of equality, diversity and inclusion.FindingsEight theoretical approaches utilised to study QIs' work experiences were recognised: (1) human capital theory, (2) career capital theory, (3) theory of practice, (4) intersectionality, (5) social identity theory, (6) sensemaking, (7) cultural identity transition and (8) the career-centred approach. The contributions and limitations of each theoretical lens were then scrutinised. Overall, research on QIs still lacks a comprehensive theoretical framework. As a step towards that, the paper proposes considering the role of organisations and labour market intermediaries, strategic view over the immigrant workforce, agency–institution play, identity–capital play and host–immigrant play.Research limitations/implicationsThe focus is on theory development and empirical papers with no clear theoretical foundation are excluded.Originality/valueThis review is the first attempt to summarise and direct the divergent research on the topic. The main contribution is setting an agenda for future research, particularly by proposing the elements of a comprehensive theoretical framework for studying QIs in the workplace.
