Hundreds of federal officers descended on a small southeast Georgia community and raided the Hyundai Metaplant " arresting 475 people in the largest sweep yet in the current Trump administration's immigration crackdown at US worksites. Previously, federal officials estimated 450 people were apprehended Thursday at the enormous site in Ellabell, about 25 miles west of Savannah, Georgia. The majority are Korean nationals, said Steven Schrank, a Homeland Security Investigations special agent in charge. Schrank said he did not have a breakdown of the arrestees' nationalities. All 475 people taken into custody were illegally in the US, Schrank said. Some crossed into the US illegally; some had visa waivers and were prohibited from working; and some had overstayed their visas, he said.
