“…However, thus far, no studies have explored how the hukou system affects ISM, which is a quantitatively significant subgroup of international migrants, especially in relation to China, which sent out more than 700,000 students only in 2019 (National Bureau of Statistic of China NBSC, 2021). This gap in the research is remarkable because most developed Chinese cities, including Beijing and Shanghai, have designed specific hukou policies oriented toward returning international students in recent years, thus providing opportunities for them, in theory, to access hukou status in these developed regions (Brooks & Waters, 2021;Zhai, 2020). Therefore, accessing hukou status in developed Chinese cities via ISM could be a potential motivation for some Chinese people to engage in ISM, but there is no existing research on the scale or mechanics of this process.…”
