WASHINGTON — Hundreds of workers at a Hyundai Motor car battery facility under construction in Georgia were detained in a major raid by U.S. authorities late on Thursday, stopping work on a plant that is one of the Korean automaker's major investments in the U.S.
About 475 workers were arrested, according to U.S. immigration officials, making it the largest single-site enforcement operation in the U.S. Department of Homeland Security's history.
President Donald Trump's administration has been escalating a crackdown on people living in the country illegally, disrupting businesses around the country, even as the White House has encouraged more inflows from foreign investors.
The arrests could exacerbate tensions between Washington and Seoul, a key ally and investor in the U.S. The countries have been at odds over the details of a trade deal that includes $350 billion of investments. Just last month, South Korea pledged $150 billion in U.S. investments — including $26 billion from Hyundai Motor — at a summit between the nations' leaders.
Homeland Security officials said the workers they arrested were barred from working in the U.S. after crossing the border illegally or overstaying visas. The investigation took place over several months, Steven Schrank, special agent in charge of investigations for Georgia, said during a press briefing.
"This was not an immigration operation where agents went into the premises, rounded up folks and put them on buses," he said.
Under Trump, Immigration and Customs Enforcement, or ICE, part of DHS, has driven the Republican leader's sweeping crackdown on migrants, bolstered by record funding and new latitude to conduct raids.
South Korea's Foreign Ministry expressed regret and concern about the raid. "The economic activities of our companies investing in the United States and the interests of our citizens must not be unduly violated during the course of U.S. law enforcement," ministry spokesperson Lee Jae-woong said in a statement on Friday.
A South Korean government official said the workers were being held at an ICE detention facility. Schrank said most of the 475 people are Korean nationals, while local Korean media said roughly 300 people detained were South Korean nationals.
A Hyundai spokesperson said, "It is our understanding that none of those detained is directly employed by Hyundai Motor Co. We prioritize the safety and well-being of everyone working at the site and comply with all laws and regulations wherever we operate."
A spokesperson at Hyundai's battery joint venture partner, South Korean battery maker LG Energy Solutions, said in a statement it was cooperating and had paused construction work. The facility, a joint venture between LGES and Hyundai Motor, was due to start operations at the end of this year, according to the battery maker.
LGES shares dropped 2.3%.
Hyundai said its production of electric vehicles at the sprawling site was not affected.
Biggest investments in Georgia
In 2023, Hyundai Motor Group and LG Energy Solution announced the $4.3 billion venture to produce EV battery cells, with each company holding a 50% stake. The plant will supply batteries for Hyundai, Kia and Genesis EV models.
The battery factory is part of Hyundai's $12.6 billion investments in the state, including the automaker's just-opened car factory, in what would be "the largest economic development project in the state's history."
Social media video footage showed a man wearing a vest with the letters HSI, an acronym for Homeland Security Investigations, telling workers in yellow safety vests, "We have a search warrant for the whole site. We need construction to cease immediately. We need all work to end on the site right now."
