Increase prevailing wage for H-1Bs. 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. 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. This will improve the number of black, Hispanic and female workers in Silicon Valley who have been passed over in favor of the H-1B program. Mark Zuckerberg’s personal Senator, Marco Rubio, has a bill to triple H-1Bs that would decimate women and minorities.
Requirement to hire American workers first. Too many visas, like the H-1B, have no such requirement. In the year 2015, with 92 million Americans outside the workforce and incomes collapsing, we need companies to hire from the domestic pool of unemployed. Petitions for workers should be mailed to the unemployment office, not USCIS.
