More than a dozen buses parked outside the arrival areas waited to take the returning workers to be reunited with their families elsewhere.
The plane, which was chartered by the South Korean government, took off from Hartsfield-Jackson Atlanta International Airport around noon ET on Thursday, a day after South Korean officials had originally hoped.
The South Korean foreign ministry said Trump delayed the repatriation in order to discuss with South Korea whether its detained nationals should remain in the U.S. to continue their work helping to set up an electric vehicle battery plant being jointly built by South Korean companies Hyundai and LG Energy Solution.
South Korean officials said it would be best for them to return home first after spending a week in ICE detention.
The workers were released shortly after 2 a.m. ET Thursday from the Folkston ICE Processing Center in rural Georgia, without any physical restraints such as handcuffs — one of South Korea’s main demands in negotiations with U.S. officials.
Construction on the $4.3 billion battery plant, part of a bigger complex in the town of Ellabell that is expected to create about 8,500 American jobs, has been delayed by at least two to three months, a spokesperson for Hyundai North America confirmed to NBC News on Thursday, citing Hyundai chief executive Jose Munoz.
Of the detained South Koreans, 47 were employed by LG Energy Solution and the rest were hired by subcontractors. Hyundai, South Korea’s largest automaker, said none of its direct employees were detained.
In a statement, LG Energy Solution apologized to the workers and their families and thanked the South Korean government and others who worked to secure their release.
“We are profoundly thankful for the extraordinary efforts to not only ensure an unusually swift release but also to carefully address various concerns, including guaranteeing that there will be no disadvantages upon re-entry,” the company said.
“Above all, our company deeply empathizes with the hardship endured by those affected.”
The workers were in the U.S. under various short-term visa programs that are commonly used for business trips but whose exact guidelines aren’t always clear. Many in South Korea have questioned the fairness of the Trump administration suddenly cracking down on a practice the U.S. has tolerated for years.
The incident has raised concerns about the potential impact on business ties with South Korea, which has pledged $500 billion in U.S. investment, including $26 billion from Hyundai, as part of tariff negotiations.
South Korean President Lee Jae Myung, who met with Trump at the White House just weeks before the raid, said Thursday that it could make companies more hesitant to invest in the U.S.
Art Wheaton, director of labor studies at Cornell University’s School of Industrial and Labor Relations, said it was standard practice for experts from other countries to travel to the U.S. to set up and install high-tech equipment, especially when it involves patents or other sensitive information such as battery cells for electric vehicles.
The jobs created by projects such as the Hyundai-LG battery plant are difficult for American workers to do if they haven’t been properly trained by those experts, he said.
“It’s not a good look when the South Korean government has to charter a plane to bring its citizens home over alleged visa inconsistencies,” Wheaton said. “It sends a message to other potential foreign investors that building plants here carries risk of arrest or detainment.”
About 145 workers from other countries, including Guatemala, Colombia, Chile, Mexico, Ecuador and Venezuela, remain in detention after the raid. The Korean Metal Workers’ Union and the United Auto Workers called for their release, saying their employers had forced them to shoulder the visa risk.
“Capital must stop shifting the burden of identified crises onto the backs of workers and instead take full responsibility for ensuring a safe work environment,” they said in a statement Thursday.
