Chicago Public Schools principals have been instructed by district officials not to let federal immigration authorities inside district buildings unless they have a criminal warrant.
Chief Education Officer Janice Jackson on Tuesday also urged principals to have parents update student emergency contact forms and include backup contacts in the event a child's parents were detained.
The action comes as the Trump administration announced a sweeping rewrite of immigration enforcement policies that targets for deportation millions of people living in the United States illegally.
District guidelines direct principals to contact CPS attorneys if immigration enforcement agents arrived at their school. The district says immigration agents should wait outside while the law department is reviewing the matter.
The new federal enforcement policies make immigrants in the U.S. illegally who are charged or convicted of any offense targets for deportation.
