Few debates in the world of tech are more heated right now than H-1B visa reform. Fans of the program, which grants 65,000 U.S. visas annually to foreign workers and another 20,000 to candidates with master’s degrees, say it brings in needed talent. Critics argue that companies abuse it to replace U.S. employees with cheaper foreign workers. In April, President Trump signed an executive order calling for a review of the system. One proposal, in a bill introduced by Rep. Darrell Issa (R-Calif.), would raise the minimum salary for H-1B workers to $100,000. To assess the potential impact, here’s a snapshot of the 46,081 applications processed in the most recent quarter.
