Five minutes of googling pulled this up. There are plenty of academic articles refuting Open Borders. https://www.bloomberg.com/graphics/2021-opinion-optional-practical-training-problems-stem-graduates-deserve-better-jobs-opportunities/ https://www.bloomberg.com/graphics/2021-opinion-optional-pra... “Wage suppression. Because foreign STEM graduates are concentrated in certain occupations, their impact on wages is stark even if absolute numbers aren’t huge. In 2018, some 53,000 foreign students earned degrees in computer science or related engineering fields, two-thirds of which were master’s degrees, according to calculations by Hal Salzman, a professor at Rutgers University’s John J. Heldrich Center for Workforce Development, and Khudodod Khudododov, a research analyst, using data from the National Center for Education Statistics. That year, the U.S. had between 96,000 and 143,000 openings in IT occupa­tions that typically went to candidates with a bachelor’s degree or higher in computer science or engineering, they found. So, OPT participants accounted for anywhere from one-third to one-half of new hires. If you add H-1B candidates, up to two-thirds of openings went to guest workers, according to Salzman.”
