The Trump administration is conducting a review of more than 55 million valid U.S. visas to identify possible violations that could lead to deportation, the Associated Press reported Thursday.

In a written response to AP, the State Department said all visa holders including tourists are under “continuous vetting” to determine their eligibility to remain in the United States. If violations are found, visas may be revoked, and individuals already in the country could face removal.

According to the report, the review expands earlier efforts that primarily targeted students and exchange visitors, marking a broader crackdown that could affect legally approved foreign residents. The Department of Homeland Security has recorded 12.8 million green-card holders and 3.6 million temporary visa holders in the U.S. as of last year.

In a related development, Secretary of State Marco Rubio announced on X that the U.S. would immediately halt the issuance of worker visas for commercial truck drivers. Rubio said foreign drivers “endanger American lives and undercut the livelihoods of American truckers.”

The State Department later clarified that visa processing for truck drivers has been paused to reassess screening and vetting protocols, stressing the importance of road safety and job protection. The Transportation Department has also tightened English-language requirements for truck drivers following accidents linked to drivers’ inability to read road signs.

Edward Alden, a senior fellow at the Council on Foreign Relations, told AP that foreign truck drivers play a key role in easing labor shortages. He cautioned that the decision reflects a broader push to discourage hiring foreign workers and warned of potential economic repercussions beyond the trucking industry.

The expanded visa review includes checks of social media activity, law enforcement records, immigration files, and other personal data, AP reported.
