This paper explores circular migrants’ skills, remittances and investments and tourism entrepreneurialship, drawing on data of 324 respondents out of which 113 are circular migrants from Tanzania. The paper reviews existing evidence on the role of circular migrants and the diaspora in promoting development in Sub-Saharan Africa, before computing odds ratios to binary data that influence whether circular migrants contribute to tourism entrepreneurialship. Factors tested for their association with tourism entrepreneurialship include a range of individual characteristics, reasons for visiting regularly, and the acquisition of financial, human and social capital while abroad. The analysis suggests that exposure, work experience abroad, remittance and regular visits are the most significant predictors of tourism entrepreneurial ventures among the circular migrants and the diaspora in Tanzania.
