LOS ANGELES — The coronavirus was not on the agenda when a legal-aid group two months ago invited farmworkers who toil in the date groves, lemon orchards and vineyards of California’s Coachella Valley to an information session about immigration issues.

But when Luz Gallegos and her team showed up over the weekend, they were cornered by people who peppered them with questions about the virus. On Monday, public health authorities announced the first two deaths from the virus in this part of Southern California, both in the Coachella Valley.

“There’s a new layer of fear in the immigrant community right now created by Covid-19,” said Ms. Gallegos, a director of TODEC Legal Center, who stood with immigrants in the parking lot of the Hemet town library, which had abruptly closed as a result of the pandemic. “We believe that some members will be afraid to seek the care they need,” she said.

Among the questions the farmworkers had: If I go to the hospital, is it going to hurt my chances of becoming a legal permanent resident? If I’m undocumented, could seeking treatment make me vulnerable to deportation? If I miss work as more people are forced to stay home, how will I feed my family and make the rent?
