In September 2025, federal agents from ICE, Border Patrol, FBI, DEA, IRS, and ATF conducted the largest single-site DHS enforcement operation in history at a Hyundai-LG joint venture battery manufacturing facility near Savannah, Georgia, detaining approximately 450-475 workers. Approximately 300 of those arrested were South Korean nationals; roughly 250 worked for HL-GA Battery Company LLC and about 50 for LG Energy Solutions. ICE alleged many had overstayed visa waiver permits (ESTAs) or held B-1 business visas that did not permit manual labor, though at least one worker with valid documentation was arrested. South Korea's president and foreign minister expressed concern and launched an investigation into whether detained workers were read their rights and reported inappropriate conduct by ICE agents. By November 2025, some workers had been released and returned to their jobs, with HL-GA Battery Co. resuming construction using a mix of new and returning workers, and the facility's opening delayed by two to three months.
