Federal agents raided the Hyundai Motor Group electric vehicle megasite in Bryan County, Georgia, arresting about 475 workers in what Homeland Security Investigations called the largest single-site immigration enforcement action in its history. Search warrants indicated investigators were probing a conspiracy to harbor undocumented workers and other illegal employment practices, and agents seized employment verification documents, computers, and storage drives. About 300 of those detained were South Korean nationals, and the South Korean government negotiated their return home, while other workers were processed through the immigration system without diplomatic intervention. One year later, the Department of Justice confirmed no criminal charges have been filed and the federal court case is closed, with no consequences for the companies that hired the workers.
