WASHINGTON (AP) — President Joe Biden is set to announce that his administration is expanding eligibility for Medicaid and the Affordable Care Act’s health insurance exchanges to hundreds of thousands of immigrants brought to the US illegally as children, according to two US officials briefed on the matter.

The action will allow participants in the Obama-era Deferred Action for Childhood Arrivals program, or DACA, to access government-funded health insurance programs. The officials spoke on the condition of anonymity to discuss the matter before the formal announcement on Thursday.

The 2012 DACA initiative was meant to shield from deportation immigrants brought to the US illegally by their parents as young children and to allow them to work legally in the country. However, the immigrants were still ineligible for government-subsidised health insurance programs because they did not meet the definition for having “lawful presence” in the US. That’s what Biden’s Department of Health and Human Services will aim to change by the end of the month.

The White House action comes as the DACA program is in legal peril and the number of people eligible under the program is shrinking.

An estimated 580,000 people were still enrolled in DACA at the end of last year, according to US Citizenship and Immigration Services. That number is down from previous years. Court orders currently prevent the US Department of Homeland Security from processing new applications. The DACA program has been mired in legal challenges for years, while Congress has been unable to reach consensus on broader immigration reforms.

DACA recipients can work legally and pay taxes, but they don’t have legal status and are denied many benefits available to US citizens and foreigners living in the US.

In recent years, millions of people in the US signed up for Medicaid, the program that provides health care coverage for the poorest Americans, during the COVID-19 pandemic. The government increased federal subsidies to drive down the cost of plans on the Affordable Care Act’s marketplace. As of last year, just 8 per cent of Americans were without health insurance, according to HHS.

But DACA recipients, as well as those in the country without documentation, are barred from joining those federally funded programs. About half of the roughly 20 million immigrants who are living in the US without documentation are uninsured, according to research from the Kaiser Family Foundation.

While there’s bipartisan support to enact some sort of protections for the immigrants, negotiations have often broken down over debates about border security and whether an expansion of protections might induce others to try to enter the US without permission. Biden, a Democrat, has repeatedly called on Congress to provide a pathway to citizenship for immigrants brought to the US illegally as children.
