(CNN) Undocumented immigrants who work as health care providers are asking for their efforts fighting the coronavirus to be taken into consideration as the Supreme Court considers the the Trump administration's bid to phase out the Deferred Action for Childhood Arrivals program.

A letter sent to the Supreme Court states approximately 27,000 Dreamers are health care workers -- including 200 medical students, physician assistants, and doctors -- some of whom are now on the front lines in hospitals across the country.

Michael J. Wishnie, a lawyer for some of the DACA recipients who are involved in the case, said he sent the letter to highlight how society has come to rely on Dreamers, one factor the justices will consider as they deliberate.

"The public health care crisis," Wishnie wrote, "throws into sharp relief DACA recipients' important contributions to the country and the significant adverse consequences of eliminating their ability to live and work without fear of deportation."
