PurposeDrawing on the whole-life perspective of career development and the conservation of resources theory, the authors consider whether self-initiated expatriates' (SIEs’) cultural intelligence (CQ) is a general, cross-domain resource that helps SIEs gain resources in the work and nonwork domains. The authors contend that CQ will be associated with greater levels of organizational and community embeddedness, which in turn will facilitate their career satisfaction. The authors also propose the role of perceived host country community diversity climate as an environmental condition that, when low, strengthens the relationships between CQ and organizational and community embeddedness.Design/methodology/approachThe authors examine the study hypotheses based on two distinct samples of SIEs (Sample 1: 169 Asian SIE professionals; Study 2: 147 SIE academics).FindingsSIEs' CQ positively relates to their organizational and community embeddedness, which in turn is associated with greater levels of career satisfaction. The authors also find that SIEs with high CQ are more likely to experience community embeddedness and career satisfaction when they perceive that the host country community diversity climate is low.Originality/valueFirst, this study goes beyond existing literature that rarely examines nonwork inputs to SIE career success. Second, extending previous CQ research with a strong organizational focus, the authors investigated how CQ influences SIEs' work and nonwork embeddedness. Third, the authors found that the absence of a peripheral ecological condition, perceived host country community diversity climate, may strengthen the direct relationship between CQ and embeddedness and the indirect relationship between CQ and career satisfaction.
