California Attorney General Xavier Becerra issued new guidance for workplaces on how to deal with federal immigration agents Tuesday.

You might remember a new state law started Jan. 1 that prohibits employers from letting ICE agents enter a workplace without a judicial warrant or I-9 Employment Eligibility Verification form request. Moreover, employees must be given 72 hours notice on the ICE I-9 inspections. ICE sent inspection notices to 77 businesses across Northern California last month.

San Francisco Assemblyman David Chiu said he authored the legislation because of the Trump administration's immigration enforcement tactics.

"The reason we felt a need to legislate in this area was because President Trump has issued unconstitutional executive orders," said Chiu. "We have anticipated that his ICE agents will also be engaged in activities that do not respect the boundaries of the Constitution."

If employers violate the new law, they could face a civil penalty up to $10,000.
