The White House on Tuesday blocked tens of thousands of undocumented immigrants and DACA recipients from getting billions of dollars in aid earmarked for college students affected by COVID-19.

It’s difficult to know how many people are affected by the Trump administration’s decision since exact figures are not kept on undocumented immigrants attending U.S. colleges. There are nearly 700,000 recipients of Deferred Action for Childhood Arrivals, making it likely that scores of students in the DACA ranks will be affected.

Officials are excluding a group of students who already face a steeper challenge in attending and finishing college – and whose legal status is in jeopardy pending a U.S. Supreme Court ruling.

The students are barred from receiving the aid because it is intended for U.S. citizens, according to the Education Department. Undocumented immigrants and DACA recipients aren’t allowed to access federal financial aid and often must rely on personal finances or private donor money to cover their education.

Denis Alvarez, a DACA receipt and student at Arizona State University, said that money would have helped her and those in her group, the Undocumented Students for Education Equity, who struggle to balance classes while dealing with the economic fallout of the coronavirus. Still, being excluded from the federal government’s help is expected.

“I am not surprised to have been left out of this because we have been left out of so many things already,” she said.
