More than 300 South Korean workers were detained in the largest single-site immigration raid in U.S. history, prompting Seoul to convene emergency talks with major investors including Hyundai, LG Energy Solution, and Samsung to address systemic visa challenges that threaten billions in bilateral investment.
The South Korean government has moved swiftly to address a brewing diplomatic and economic crisis, convening an emergency meeting with major companies investing in the United States, including Hyundai Motor Group and LG Energy Solution, to discuss responses to a recent mass detention of Korean workers in Georgia. The unprecedented roundtable discussion signals Seoul’s recognition that visa-related workforce challenges could jeopardize the country’s massive $26 billion investment commitment to the United States.

Historic Immigration Raid Rocks Korean Business Community
The crisis erupted on September 4, 2025, when U.S. Immigration and Customs Enforcement agents arrested 475 people, most of them South Korean nationals, when hundreds of federal agents raided Hyundai’s sprawling manufacturing site in Georgia where the Korean automaker makes electric vehicles. The operation was the largest single-site enforcement operation in the history of Homeland Security Investigations, targeting what Georgia officials have called the state’s largest economic development project.
Federal agents descended on the Hyundai site like it was a “war zone,” according to a construction worker at the electric car plant. The dramatic images released by ICE showed workers being handcuffed and loaded onto buses, creating a diplomatic flashpoint between two key allies just weeks after South Korean President Lee Jae Myung’s White House summit with President Trump.
Emergency Corporate Summit Signals Policy Shift
On September 8, the Ministry of Trade, Industry and Energy (MOTIE) and the Korea Enterprises Federation hosted a “U.S. Investment Enterprises Roundtable” at the FKI Tower in Yeouido, Seoul. The meeting, chaired by Deputy Trade Minister Park Jong-won, brought together executives from Hyundai Motor Group, LG Energy Solution, SK On, Samsung SDI, Samsung Electronics, SK Hynix, LG Chem, HD Hyundai, Hanwha Solutions, and LS.
The gathering represented a who’s who of Korean industrial power, collectively responsible for tens of billions of dollars in U.S. investments across semiconductors, electric vehicles, batteries, and advanced manufacturing. These companies have been at the forefront of Korea’s economic partnership with the United States, particularly in the wake of the Inflation Reduction Act and CHIPS Act, which have incentivized Asian manufacturers to establish American operations.
Discussions focused on workforce deployment at U.S. investment sites and visa-related challenges. The government listened to companies’ recommendations for improving visa processes and signaled its readiness to explore measures such as creating a new visa category for short-term dispatched workers or enhancing flexibility within existing frameworks.
The Hyundai-LG Georgia Megaproject: A $7.6 Billion Flagship Investment
The Georgian facility at the center of the controversy represents one of the most significant foreign direct investments in U.S. history. Hyundai Motor Group and LG Energy Solution have committed over $7.6 billion to their joint electric vehicle and battery manufacturing complex in Bryan County, Georgia, creating 8,500 direct jobs. Hyundai Motor Group’s total investments in Georgia are expected to create nearly 40,000 direct and indirect jobs and $4.6 billion in individual earnings every year.
The facility boasts a highly connected, automated, and flexible manufacturing system, which organically connects all elements of the EV and hybrid ecosystem. All processes of production—order collection, procurement, logistics and production—are optimized utilizing AI and data. The 30 GWh facility will be able to support the production of 300,000 units of EVs annually at full operations.
The project’s scale extends far beyond the immediate facility. Since the company announced its first U.S. plant solely dedicated to electric vehicles, suppliers have pledged to invest $2.2 billion and to hire 5,300 people. The investment is part of what industry analysts call an “electric vehicle and battery land rush” across the United States, driven by the Inflation Reduction Act’s requirements for domestic assembly and North American content.
Visa System Failures Threaten Investment Security
The detained workers highlight a critical flaw in the current visa framework governing Korean business operations in the United States. Of the 475 workers detained at the joint venture site in Georgia run by LG Energy Solution and Hyundai Motor, about 300 reportedly held B-1 visas or ESTA permits. These visas are designed for business visitors, not long-term workers, creating a legal gray area for Korean technicians and engineers working on complex industrial projects.
“The subcontractor staff who were detained were not doing basic construction but installing and inspecting line equipment, fixing defects and breakdowns. They are often called in to urgently recalibrate and adjust conditions — work that lasts less than a couple of days. Who is going to apply for an H-1B or employment visa just for that?” an industry official said on condition of anonymity.
Georgia immigration attorney Charles Kuck told CNN two of his clients were detained at the raid after having arrived from South Korea under a visa waiver program that allows them to travel for tourism or business for up to 90 days. The clients, both engineers, came to the US “to advise briefly on the work” and were planning to return to South Korea shortly.

The E-4 Visa Solution: A Decade-Long Diplomatic Struggle
The Ministry of Foreign Affairs has long sought to establish a new employment visa (E-4) for up to 15,000 Korean professionals, but related legislation has stalled in the U.S. Congress. The proposed E-4 visa program would mirror arrangements the United States already maintains with other close allies and trading partners.
The US already allocates annual professional visa quotas to free trade agreement partners such as Mexico and Canada (unlimited), Singapore (5,400) and Australia (10,500). The latest proposal for a bill to issue E4 visas for 15,000 Korean professionals annually is on the verge of expiring once again due to the upcoming dissolution of the House of Representatives next January.
Korean companies are now urging the government to step up diplomatic efforts for the US Congress to pass a bill that grants new 15,000 E-4 visas annually to Korean employees. Since the bill was proposed in 2013, it has been pending in the US Congress.
Corporate Response and Operational Adjustments
The detention crisis has prompted immediate operational changes across Korean corporations with U.S. investments. LG Energy Solution said it was suspending most of its business trips to the US, with “Currently traveling employees advised to immediately return home or remain at their accommodations, considering their current work status”.
Korean companies are rushing to revise US business travel plans and tighten internal guidelines after last week’s immigration raid at a battery plant construction site in Georgia. The immediate operational disruption threatens to slow progress on critical infrastructure projects that both governments consider strategically important.
LG Energy Solution Chief Human Resources Officer Kim Ki-soo said “The ‘prompt release’ of the detained individuals is our top priority right now”. The company confirmed that 47 of its employees were detained, 46 of them Korean. Another 250 personnel from “equipment partner companies,” most of them Korean, were also being held.
Swift Diplomatic Resolution and Future Implications
South Korea’s presidential chief of staff Kang Hoon-sik announced Sunday that negotiations had been finalized on the workers’ releases, with South Korea planning to send a charter plane for them as soon as the remaining administrative steps are completed. The rapid diplomatic resolution underscores the economic and strategic importance both nations place on maintaining stable business relationships.
“To prevent a recurrence of similar cases, we will work together with the Ministry of Trade, Industry and Energy and the companies concerned, to review and improve the visa system and stay status of people traveling to the US for investment projects,” Kang said Sunday.
However, the incident has broader implications for Korean-American economic relations. Tom Homan, Trump’s border czar, told CNN that “we’re going to do more work site enforcement operations,” suggesting that similar raids could target other Korean investments.
Economic Stakes and Regional Impact
The timing of the crisis could not be more challenging for Korean-American economic cooperation. The raid came just 11 days after a summit between Trump and Lee at the White House, where South Korean firms pledged $150 billion in U.S. investments. In July, Seoul pledged another $350 billion in U.S. projects in an effort to reduce Trump’s threatened tariffs.
South Korean companies invested a combined $7.4 billion in the US in the first nine months of 2023, nearly matching the $7.5 billion they spent on their US facilities for all of 2022. For the entire 2023 year, their capital expenditure in the US is estimated to have quadrupled compared to the $2.3 billion in 2020.
The Georgia facility alone represents a transformational investment for the region. The deal calls for Hyundai and battery maker LG Energy Solution to invest $7.6 billion in the Georgia plant and hire 8,500 workers by the end of 2031. Economic Development Commissioner Pat Wilson said Hyundai is projected to have a direct payroll of $4.7 billion over the next 10 years. The company has promised to pay workers a yearly average of $58,105, plus benefits.
Technical Workforce Challenges in Advanced Manufacturing
The visa crisis highlights the sophisticated technical requirements of modern electric vehicle and battery manufacturing. “We need more than three times as many professionals compared to two to three years ago, but it is becoming more difficult to find them,” said a Korean parts maker official.
Despite their aggressive investments in the US, the number of Koreans obtaining H-1B visas has hardly increased. According to the US Citizenship and Immigration Services, 2,019 South Koreans were newly awarded the H-1B in 2022, up 7.9% compared to 2020. But the number has remained between 1,800 and 2,000 for several years.
This workforce bottleneck forces Korean companies to rely on temporary solutions. A Korean rechargeable battery materials company is hiring temporary Korean employees with one-year optional practice training (OPT) visas issued for international graduates. If the temporary workers fail to earn an H-1B visa within one year, they must leave the US.
Looking Forward: Policy Recommendations and Industry Outlook
Kim Tae-hwang, an international trade professor at Myongji University, stressed that the Korean government should push harder in visa negotiations. “The Korean government should use this incident to press the US to allow Korean technical personnel to obtain visas. These workers are not the kind of people who cause problems with drugs or guns, and companies are not asking to bring in 10,000 workers at a time — just a few hundred or a few thousand”.
The emergency meeting represents Seoul’s most coordinated response yet to the visa challenge. Seoul intends to raise these proposals with Washington in future talks, signaling that visa reform will become a top priority in bilateral economic discussions.
The resolution of this crisis will likely serve as a template for how both nations manage similar challenges in the future. With Korean companies planning hundreds of billions in additional U.S. investments over the coming decade, establishing a stable framework for technical worker mobility has become essential for maintaining the momentum of economic partnership between the two allies.
As both governments work to prevent similar incidents, the success of the ongoing Korean investment wave in American manufacturing may ultimately depend on their ability to create visa policies that match the realities of modern global industrial cooperation. The stakes extend far beyond individual companies to encompass the broader strategic partnership between two of the world’s most technologically advanced economies.
