Purpose: Externalities influence the career trajectories of self-initiated expatriates (SIEs) and their respective career crafting. This study aims to explore the international career crafting of SIEs (encompassing their proactive career reflection and construction), taking the combined external influences of complexity, chance and change into consideration. Design/methodology/approach: The authors employ a qualitative (interpretative) approach, combining career crafting and the chaos theory of careers (CTC) to further understand, from an individual standpoint, the impact of externalities on the career crafting strategies of 24 SIEs who have relocated within the European Union. Findings: The authors show that SIEs' proactively craft their careers to varying degrees and with varying frequency. The CTC – incorporating complexity, chance and change – allows for a more nuanced understanding of SIEs' career crafting. Originality/value: This paper applies the concept of career crafting to an international context, exploring the impact of externalities on SIEs' careers. In this way, the authors combine two previously separate theories, extend the application of career crafting to an international career context and emphasise the role of temporality and the whole-life view of career in SIEs’ career crafting approach.
