Leo Medina was working an overnight shift at the Dallas hospital where he works when the news hit him: A federal appeals court in New Orleans had struck a severe blow to Deferred Action for Childhood Arrivals, the Obama administration-era policy that protects undocumented people brought to this country at a young age. 

The news was a blow nationwide for thousands of DACA recipients, Medina included, and those eligible for DACA. It struck a particularly sharp note in his mixed-status family: While he has DACA protection, his younger brother, Carlos Medina, also brought to the U.S. as a minor, does not. After Wednesday’s ruling, Carlos Medina’s hopes of receiving DACA dimmed to a flicker.

“Devastating,” Leo Medina, 24, said. “To me, my family’s everything. Doing everything together makes us stronger. Seeing him struggling will make it devastating for the both of us.”

The decision from a three-judge panel of the U.S. Court of Appeals for the 5th Circuit sent shockwaves to DACA-eligible recipients across the United States, including families with both DACA recipients and DACA hopefuls, like the Medinas. 

The panel agreed with a lower court ruling that DACA, which has protected hundreds of thousands of young immigrants from deportation and allowed them to legally work, was unlawful but said current recipients could continue to renew their status every two years, as required by the program. It sent the case back to a Texas courtroom to decide on a new Biden administration regulation on the program. 

Created by President Barack Obama in 2012 as a temporary solution until Congress passed more permanent legislation, DACA has protected more than 800,000 recipients over the past decade. Today, more than 611,000 people are in the program. Another 80,000 have applied for DACA but their applications are in limbo while the case plays out in court. 

The DACA-eligible population earned $23.4 billion in 2017, up from almost $19.9 billion in 2015, according to a report by the New American Economy, a research fund. More than 93% of DACA-eligible individuals were actively employed in 2017.

Biden administration officials denounced the ruling and called on Congress to pass legislation to protect immigrants brought to the United States at a young age. 

“I am deeply disappointed by today’s #DACA ruling and the ongoing uncertainty it creates for families and communities across the country,” Homeland Security Secretary Alejandro Mayorkas said in a tweet. “We are currently reviewing the court’s decision and will work with @TheJusticeDept on an appropriate legal response.”
