There are not tens of millions of unauthorized immigrants in the U.S. receiving federal health care benefits.

The unauthorized population reached a record 14 million in 2023, according to an August 2025 research estimate. 

Unauthorized immigrants are not eligible to enroll in federally funded health coverage. 

That includes Medicaid (low-income people), Medicare (age 65 and over) and the Children’s Health Insurance Program (CHIP). And they aren’t eligible to buy coverage through the Affordable Care Act (Obamacare) marketplaces.

Federal Medicaid can reimburse hospitals for providing emergency care to unauthorized immigrants, but that is not coverage for individuals.

Vice President JD Vance said Aug. 28 in La Crosse, Wisconsin, that health care benefits can’t be sustained “if you allow tens of millions of people” into the U.S. without authorization “and give them those benefits.”

White House spokespersons did not return requests for comment.
