Of interest to readers and policymakers in countries that receive migrants through family reunion and manpower admission schemes from low-income countries and strive to assimilate them into their communities, this book presents a case study of the integration of migrants from Mainland China in Hong Kong. It shows that early optimism of quick economic assimilation has given way to a more realistic view of a long, arduous process extending to the second generation. While the case of Hong Kong is unique in a number of ways, the book serves as a useful policy reference for other countries that attempt to balance the intake of migrants for family reunion with the admission of high-quality migrants who possess skills in demand in the economy.
