CHICAGO — Immigration hotlines are buzzing. Legal clinics are seeing an influx of clients. Public schools are fielding frantic questions from parents and students.

Since the election, Donald Trump’s tough talk on immigration has stirred anxiety nationwide among immigrants regardless of legal status. They are turning to lawyers, schools, advocacy groups and congressional offices for help.

“We’re operating with a lot of unknowns, and a certain amount of fear comes with that,” said Vanessa Esparza-Lspez, a managing attorney at the Chicago-based National Immigrant Justice Center.

In Chicago, a hotline run by the state’s largest immigrant-rights group received more than 330 calls in the week after the election, compared with the usual 100 or so. Denver school officials sent a letter to parents in response to questions about the election’s effect on students living in the country illegally.

The New York Legal Assistance Group said it’s receiving 40 to 60 daily calls about immigration, up from 20 to 30. The Coalition for Humane Immigrant Rights of Los Angeles reported 19 walk-ins on a single day, all with citizenship questions.
