Reverse brain drain is a form of brain drain where human capital moves in reverse from a more developed country to a less developed country that is developing rapidly. These migrants may accumulate savings, also known as remittances, and develop skills overseas that can be used in their home country.〔Stark, O & Bloom, D.E. (1985). The new economics of labor migration. The American Economic Review. 75(2) p.173-178.()〕 Brain drain can occur when scientists, engineers, or other intellectual elites migrate to a more developed country to learn in its universities, perform research, or gain working experience in areas where education and employment opportunities are limited in their home country. These professionals then return to their home country after several years of experience to start a related business, teach in a university, or work for a multi-national in their home country. Their return is this "Reverse Brain Drain". The occurrence of reverse brain drain mostly depends on the state of the country’s development, and also strategies and planning over a long period of time to reverse the migration. Countries that are attractive to returning intelligentsia will naturally develop migration policies to attract foreign academics and professionals. This would also require these countries to develop an environment which will provide rewarding opportunities for those who have attained the knowledge and skills from overseas.〔OECD Observer. (2002). "International mobility of the highly skilled" Policy Brief. p.6〕 In the past, many of the immigrants from developing countries chose to work and live permanently in developed countries; however, the recent economic growth that has been occurring back in their home countries - and the difficulty of attaining long-term work visas - has caused many of the immigrants to return home.〔Lee, Jenny J. & Kim, Dongbin (2010). "Brain gain or brain circulation? U.S. doctoral recipients returning to South Korea". Higher Education. 59:627-643. . p. 629 ()〕 ==Definition== The term ‘reverse brain drain’ is closely tied with brain drain and brain gain because reverse brain drain is a migratory phenomenon that results due to the brain drain of the intellectual elites from developing countries and is the mirror image of the benefit of an inflow of high quality human resources which is brain gain.〔Song, Hahzoong. (1997). "From brain drain to reverse brain drain: Three decades of the Korean experience. Science, Technology and Society. 2(2):317-345. p. 332〕 Reverse brain drain is sometimes related to the term ‘brain circulation’, which is when migrants return to their own country on a regular or occasional basis, sharing the benefits of the skills and resources they have acquired while living and working abroad.〔Global Commission on International Migration. (2005). "Migration in an interconnected world: New directions for action"()〕 An example of the benefits for the host countries, especially developing countries, are the payments of remittances. This provides a reason for governments to issue new legislation and tax rules that encourage outward migration and remittances.〔Elizabeth Chacko. (2007). "From brain drain to brain gain: reverse migration to Bangalore and Hyderabad, India's globalizing high tech cities". GeoJournal, 68(2-3), 131-140. p. 134 ()〕 However, "brain circulation" is known as the extended definition of brain gain with an emphasis on human capital circulation across nations in the global market, benefiting both the sending and receiving nations; in addition it is considered a two-way flow of skill, capital, and technology, unlike brain drain and reverse brain drain.〔Saxenian, AnnaLee (2005).
