CHICAGO (AP) — Immigration hotlines, legal clinics and public schools around the country have been fielding a flood of questions about immigration since Donald Trump’s election.

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

The most urgent inquiries have come from young people benefiting from Deferred Action for Childhood Arrivals, a federal program started by President Barack Obama in 2012. It allows immigrants brought to the country illegally as children to avoid deportation and get work permits. Some are worried that they could be the first target.

As a candidate, Trump pledged to build a border wall and to deport millions of immigrants living in the country without permission.
