Purpose This paper examines the drivers of brain gain by investigating the motivations of migrants who plan to return and contribute to their home country. It focuses on highly skilled Sudanese migrants in Japan, including a group of “plan-to-return” migrants (P-group), who intend to gain knowledge abroad that they will use to contribute to their homeland upon their return. Design/methodology/approach The participants are 24 highly skilled Sudanese migrants in Japan, 10 of whom are part of the P-group. To understand their motivation to contribute to their home country, the study applies the qualitative life course approach, using Elder's four life course themes: lives in time and space, the timing of lives, linked lives and human agency. Findings The P-group is characterised by a high level of motivation for self-development, which motivates them to study abroad. The analysis finds that the P-group's drive to contribute had been nurtured by a spirit of mutual aid in Sudanese society, which emphasises Islamic values and social ties. Religious norms, personal interactions and emotional ties to Sudan are especially influential on the P-group's motivation to contribute to their home society. Originality/value This study identifies drivers that lead to brain gain. Whereas previous studies have noted the relationship between return intentions and willingness to contribute to the home countries; they have not investigated influences on motivations to contribute. The results suggest that Sudan might already possess a system for local human resource development to encourage brain gain.
