Those who come into the U.S. on an H-1B visa for highly skilled work receive salaries higher, on the median, than U.S. workers engaged in the same work.

HRDive reports that while employers planned to pay high-skilled H-1B visa holders a median salary of $80,000 in 2016, up from $69,000 a decade ago, their U.S. counterparts weren’t so lucky. The data came from new U.S. Citizenship and Immigration Services data that made salary information on H-1B visa workers public for the first time. Those workers generally hold positions in science and mathematics.

A Pew Research analysis, however, found that U.S. workers in those fields and working in similar jobs had a notably lower median salary of $75,036 in 2016. The analysis cited data from the U.S. Bureau of Labor Statistics. American workers in those positions earned $73,979 in 2007, so they haven’t seen anywhere near the salary increases that H-1B workers have over the past ten years.
