Allegations have surfaced that a popular visa program is actually being misused by U.S. companies to fire thousands of U.S. workers and replace them with foreign labor.

Tucker Carlson pointed out on "Fox and Friends Weekend" that the H1-B program would seem to violate U.S. immigration law, which requires that the hiring of a foreign worker will not adversely affect the wages and conditions of U.S. workers comparably employed.

Professor of Public Policy at Howard University Ron Hira said that the tech industry in particular has tried to paint the visa program as a good deal, when in reality it's just undercutting Americans.

Hira explained that "guest workers," not immigrants, are brought in for up to six years on H1-B visas. The employer can often pay the guest workers 40 to 50 percent less than American workers.

"So there's a big incentive for employers to bring these workers in and to replace Americans," Hira said.

He added that recently terminated employees at Southern California Edison were essentially told to "train your foreign replacement."

"It's not about skills. It's not about need. It's all about the fact that [companies] can bring in these guest workers at a lot less money."
