The number of temporary guest workers allowed into the country every year would double if the Schumer-Rubio bill currently being considered by the Senate became law, according to a new study by the Center for Immigration Studies.

“The Gang of Eight bill would allow an unprecedented number of temporary workers into the country each year,” study author and CIS Director of Policy Studies Jessica Vaughan said. “This is an addition to the approximately 700,000 temporary worker visas that we are currently admitting annually.”

Vaughan found that after an initial surge of 1.6 million more guest workers in year one of Schumer-Rubio, thanks largely to a 950,000 surge in V-1 family visas, the additional flow would eventually level off to about 620,000 more visas every year. This means, in total, Schumer-Rubio envisions importing 1.3 million guest workers each year.

“That’s about four times higher than the 2007 Bush-Kennedy bill. And we’re talking about increasing these admissions at a time when our economy is much worse,” Vaughan said.

One new temporary worker visa overlooked by many analysts is the Schumer-Rubio E-4 visa, which would create 5,000 new visas for every country that has a free trade agreement with the United States. This works out to another 150,000 new visas a year, which is about as large as the expanded Schumer-Rubio H-1B skilled visa cap of 170,000 a year.

“The vast majority of these admissions come in visa programs where the employer is not required to show that they’ve tried and failed to find a U.S. worker, or demonstrate that there is even a shortage of these workers,” Vaughan explained. These programs are “guaranteed to have harmful effects on Americans in those same occupations.”

“These are all temporary workers,” Sen. Jeff Sessions, R-Ala., said of the study. “These are not people that come as immigrants who would presumably stay and build a business and are going to be permanent. They are people who would come in and compete for jobs on a temporary basis against unemployed Americans.”
