Diaspora has been increasingly recognized by practitioners and scholars as an important factor of development in developing economies. Through their remittances and expertise, diaspora members have become an important source of foreign direct investment and managerial capabilities. Although the literature is glutted with examples of the impact of diaspora in fostering international entrepreneurship and reducing poverty, a theoretical foundation and framework is needed to explain this impact. This study explores a theoretical foundation of the diaspora entrepreneurship. A framework identifying the determinants of the diaspora’s international new venture creation in the country of origin is developed. The study suggests that diaspora international entrepreneurship depends on the level of altruistic motivation, need of social recognition, entrepreneurial opportunities, friendliness and receptivity of the home country, as well as integration of and support to immigrants in the host countries. Propositions for diaspora entrepreneurship are developed.
