U.S. immigration authorities on Thursday raided the sprawling site where Hyundai manufactures electric vehicles in southeast Georgia, conducting a search that shut down construction on an adjacent factory being built to produce EV batteries. Hyundai Motor Group began manufacturing EVs a year ago at the $7.6 billion plant, which employs about 1,200 people. U.S. Immigration and Customs Enforcement spokesman Lindsay Williams confirmed that federal authorities were conducting an enforcement operation at the 3,000-acre (1,214-hectare) site west of Savannah.
