As of 2023, there were 47.1 million immigrants residing in the U.S., including 22.4 million noncitizen immigrants and 24.7 million naturalized citizens, who each accounted for about 7% of the total population.

Noncitizen immigrants are more likely to be uninsured than citizens because they have more limited access to private coverage due to working in jobs that are less likely to provide health benefits. They also face eligibility restrictions for federally funded coverage options, including Medicaid, CHIP, the ACA marketplace and Medicare.

KFF focus groups with immigrant families during the first Trump administration found that restrictive immigration policies led to increased fears among immigrant families across immigration statuses. That had negative effects on health and well-being and led to reluctance to seek health care and enroll in programs for which lawfully present immigrants were eligible. Mass deportations could also negatively affect health care and other industries by depriving them of workers.

A KFF-Los Angeles Times partnership survey of immigrant adults, released in September 2023, shows most feel they found a better life for their families in this country, but many also face economic hardships and discrimination.

This report, drawing upon the main survey findings, shows how these challenges extend to health care. Many immigrants have difficulty accessing and using health care in the U.S. due to higher uninsured rates, affordability challenges, linguistic and cultural barriers, and immigration-related fears. The survey also shows the difficulties immigrants face in obtaining health coverage and underscores the role of coverage in access to care.
