His comments Wednesday night highlighted a major issue facing the technology sector: Should American tech companies scour the globe to import the most qualified technicians or pay top dollar for American engineers?
Those are the questions surrounding the H1-B visa program, a practice of granting U.S. immigration and residency rights to foreign workers qualified in so-called "specialty occupations."
Zuckerberg has said he supports increasing the number of these visas, while Trump's website declared the program encourages Silicon Valley companies to pass over black, Hispanic and female workers.
"We graduate two times more Americans with STEM degrees each year than find STEM jobs, yet as much as two-thirds of entry-level hiring for IT jobs is accomplished through the H-1B program," Trump's campaign website reads. "More than half of H-1B visas are issued for the program's lowest allowable wage level, and more than eighty percent for its bottom two. Raising the prevailing wage paid to H-1Bs will force companies to give these coveted entry-level jobs to the existing domestic pool of unemployed native and immigrant workers in the U.S., instead of flying in cheaper workers from overseas."
