President Donald Trump’s push for the largest mass deportation in history has had an outsized impact on the child care field, which is heavily reliant on immigrants and already strained by a worker shortage. Immigrant child care workers and preschool teachers, the majority of whom are working and living in the U.S. legally, say they are wracked by anxiety over possible encounters with ICE officials. Some have left the field, and others have been forced out by changes to immigration policy. About one-fifth of the child care workforce is Latino, and one-fifth were born outside the United States.
