Academic research has shown significant interest in international student
mobility, with previous literature primarily focusing on the migration industry
from a political and public policy perspective. For many countries,
international student mobility plays a crucial role in bolstering their
economies through financial gains and attracting skilled immigrants. While
previous studies have explored the determinants of mobility and country
economic policies, only a few have examined the impact of policy changes on
mobility trends. In this study, the researchers investigate the influence of
immigration policy changes, particularly the optional practical training (OPT)
extension on STEM programs, on Asian students' preference for enrolling in STEM
majors at universities. The study utilizes observational data and employs a
quasi-experimental design, analysing the information using the
difference-in-difference technique. The findings of the research indicate that
the implementation of the STEM extension policy in 2008 has a significant
effect on Asian students' decisions to enroll in a STEM major. Additionally,
the study highlights the noteworthy role of individual factors such as the
specific STEM major, terminal degree pursued, and gender in influencing Asian
students' enrollment decisions
