Vice President JD Vance and the Department of Labor’s Inspector General announced on Wednesday a sweeping new investigation into what officials describe as widespread abuse of U.S. work visa programs, calling the effort a major step in the Trump administration’s broader crackdown on immigration fraud and workplace exploitation.
The announcement came during an anti-fraud event in Milwaukee, where Vance said the investigation is designed to protect American workers by ensuring that employment opportunities are awarded fairly and that visa programs are not manipulated to benefit employers seeking cheaper labor. According to administration officials, the Department of Labor has already issued dozens of subpoenas as investigators begin examining suspected fraudulent schemes involving employment-based visas.
Vance argued that while legal immigration programs can provide important benefits to the United States, they must operate according to the law and serve the interests of American workers first. He emphasized that the administration supports highly skilled legal immigration but believes that abuse of the system has harmed both U.S. citizens and legitimate foreign workers.
“We want to make sure these programs work the way Congress intended,” Vance said during the event. “They were created to attract exceptional talent, not to become tools that allow companies or criminal organizations to exploit workers or suppress wages.”
The investigation is being led by the Department of Labor’s Office of Inspector General under Inspector General Anthony D’Esposito. According to D’Esposito, investigators have uncovered evidence suggesting that fraudulent visa applications have become part of sophisticated schemes involving labor brokers, dishonest employers, and organized criminal networks operating both inside and outside the United States.
Speaking to the New York Post, D’Esposito said the suspected fraud has already cost the U.S. medical industry hundreds of millions of dollars while extending into several other sectors of the economy. Authorities believe some operations may involve forced labor, human trafficking, identity fraud, and wage exploitation.
“Labor’s Office of Inspector General has uncovered widespread schemes in which employers and labor brokers submitted fraudulent applications, exploited foreign workers through coercive wage-kickback arrangements, and undercut American workers by flooding the market with below-wage labor,” D’Esposito said.
Officials allege that in some cases foreign workers were recruited with promises of legitimate employment, only to face abusive working conditions after arriving in the United States. Some workers reportedly had portions of their wages taken back by recruiters or employers through illegal kickback arrangements, while others were allegedly threatened with deportation if they reported abuse or attempted to leave their jobs.
Investigators also believe that criminal organizations may have used fraudulent employment documents to help facilitate illegal immigration or generate profits through labor trafficking schemes. According to D’Esposito, the alleged fraud extends far beyond individual companies and may involve networks operating across multiple states.
“This is another example where fraud is fueling violent crime,” D’Esposito said. “This visa fraud is tied to cartels, is tied to transnational gangs.”
He warned that the consequences reach beyond economic concerns. If fraudulent hiring practices infiltrate hospitals, medical clinics, or physicians’ offices, officials argue that patient safety could also be affected. Authorities say ensuring that healthcare professionals meet legal employment standards remains an important component of the investigation.
A major focus of the inquiry will be the H-1B visa program, one of the most widely used employment-based visa systems in the United States. The H-1B program allows American employers to hire foreign professionals for specialty occupations requiring highly specialized knowledge and at least a bachelor’s degree or equivalent experience. Industries including technology, engineering, medicine, finance, research, and higher education rely heavily on the program to fill positions requiring advanced skills.
The administration argues that while the H-1B system has played an important role in attracting global talent, it has also become vulnerable to abuse by employers seeking to reduce labor costs.
“What’s happening way too much is that big corporations and fraudsters overseas are using this program to undercut the wages of American workers,” Vance said. “What we’re doing in the Trump administration, we’re saying, ‘No more.’”
Investigators will also examine the PERM labor certification process, which serves as the first step for many foreign nationals seeking employment-based permanent residency, commonly known as a green card. Officials intend to review cases where employers may have falsely claimed labor shortages or manipulated hiring processes to favor foreign applicants over qualified American workers.
According to the Department of Homeland Security, previous assessments suggested that as many as 21 percent of H-1B visa petitions may contain fraudulent information or technical violations requiring additional scrutiny. While officials caution that not every flagged petition represents intentional fraud, they say the statistics justify a comprehensive review of the system.
The investigation is expected to include audits of employers, interviews with workers, reviews of immigration records, and coordination among several federal agencies, including the Department of Labor, the Department of Homeland Security, and federal law enforcement authorities.
Data from the Pew Research Center illustrates the significant role foreign professionals play in the H-1B program. Approximately 73 percent of H-1B recipients come from India, with many possessing advanced degrees in engineering, computer science, mathematics, and other technical fields. Large technology companies including Amazon, Google, Meta, Microsoft, and Apple rank among the largest users of H-1B workers, although visa holders are also employed throughout healthcare, manufacturing, scientific research, universities, and financial services.
Geographically, California receives the highest number of H-1B approvals, followed by Texas, New York, Illinois, and Washington. The number of approved petitions increased significantly in recent years, reaching approximately 442,425 in 2022 during the Biden administration, reflecting continued demand for highly skilled workers across numerous industries.
Supporters of the administration’s initiative argue that stronger enforcement is necessary to preserve confidence in legal immigration while preventing employers from exploiting loopholes. They contend that fraudulent applications not only harm American workers but also disadvantage honest employers who follow immigration laws and pay competitive wages.
Critics, however, have cautioned against broadly characterizing the H-1B program as abusive, noting that many American businesses rely on international talent to address shortages in specialized fields. They argue that enforcement efforts should focus on fraudulent actors rather than limiting legitimate pathways for skilled professionals who contribute to innovation and economic growth.
The administration maintains that its investigation is not aimed at lawful immigrants or qualified foreign professionals who follow the rules. Instead, officials say the objective is to identify fraudulent applications, dismantle criminal networks, prosecute employers who knowingly violate federal law, and restore confidence in employment-based immigration programs.
Federal investigators are expected to continue issuing subpoenas and gathering evidence in the coming months, with additional enforcement actions possible as the investigation expands. Administration officials indicated that criminal prosecutions, civil penalties, and regulatory reforms could follow if widespread violations are confirmed.
Ultimately, the Trump administration says the investigation reflects its broader commitment to strengthening immigration enforcement, protecting the integrity of legal visa programs, combating fraud, and ensuring that employment opportunities are awarded fairly. By targeting alleged abuse within work visa systems, officials argue they are working to prioritize American workers while preserving legal immigration pathways for individuals who meet the requirements and comply with U.S. law.
