Six “Dreamers” — immigrants brought into the country illegally as children — are suing the Trump administration over President Trump’s decision to end the Deferred Action for Childhood Arrivals (DACA) program, Reuters reported Monday.

The lawsuit, filed in San Francisco federal court Monday, is the first to be brought against the administration by recipients of the program. DACA provided its recipients with work permits and protection from deportation.

Two of the people suing Trump are Dulce Garcia, a San Diego attorney, and Jirayut “New” Latthivongskorn, a fourth-year medical student at the University of California, San Francisco.

Latthivongskorn, who was brought to the U.S. from Thailand when he was 9, told Reuters that he might not be able to carry out his medical residency in a few months if he’s unable to work legally.

“I have all these big ideas about how I want to change the world and change systems around health care,” Latthivongskorn said. “The fact I might not be able to get there is troubling and frustrating.”

This is the latest lawsuit brought against Trump over his decision to end DACA. Several states have joined together to file a massive lawsuit to block Trump from stopping the program, and the University of California is also suing over the move.

Trump is ending the program with a six-month window, saying it gives Congress the opportunity to pass legislation to extend the protections for people brought to the U.S. as minors.

Trump and Democratic leaders appeared to reach an agreement last week about moving forward on DACA legislation, with Democrats pushing for Congress to pass a bill restoring DACA-like protections.
