The Albany Gazette - S. Korean workers arrive home after US detention

South Koreans made up the majority of the 475 people arrested at a Hyundai-LG battery factory site in the state of Georgia, triggering a delicate effort to resolve the thorny situation between close allies.

The Korean Air Boeing 747-8I, with more than 310 South Koreans on board, departed from Atlanta and touched down on the runway at South Korea's main gateway in Incheon.

"Everything at Atlanta went smoothly," a foreign ministry official told AFP on Friday, ahead of the workers' arrival at around 3:25 pm (0625 GMT).

"The plane departed as scheduled with the planned number of passengers."

Asia's fourth-largest economy maintains multiple plants in the United States, and has heeded Washington's push to onshore manufacturing and boost investment in America.

The Georgia raid was the largest single-site operation conducted since US President Donald Trump launched a sweeping immigration crackdown, a top political priority since he returned to office in January.

Experts say most of the detained South Korean workers were likely on visas that do not permit hands-on construction work.

At the Incheon airport, people were seen holding a satirical placard depicting President Trump in an ICE uniform, wearing a gun, alongside the words, "We're friends, aren't we?"

One older man, who was not related to the workers, also staged a protest against the raid, holding a picket that read: "You told us to invest, only to arrest us! Is this how you treat an ally?"

President Lee Jae Myung called the raid "bewildering" and noted it could have a chilling effect on future investment.

He added that Seoul was negotiating with Washington "to ensure that visa issuance for investment-related purposes operates normally".

At the Hyundai factory site, construction will now be set back due to labour shortages, Chief Executive Officer Jose Munoz said.

"This is going to give us minimum two to three months delay, because now all these people want to get back," he said.

"Then you need to see how can you fill those positions. And, for the most part, those people are not in the US."

The Korean Confederation of Trade Unions (KCTU), one of the country's largest umbrella union groups, called for an apology from Trump and for Seoul to halt US investment plans.

"The Trump administration's excessive mass arrests and detentions were a clear violation of human rights," it said in a statement sent to AFP.

"The KCTU stands in full solidarity with the workers returning today and strongly urges President Trump to issue an official apology and calls for (South Korea's) suspension of investments in the US."

- Minimise impact -

LG Energy Solution -- which said 47 of its employees were arrested, along with about 250 people working for its contractor -- thanked the Seoul government for its support.

Seoul sent a task force and flew in top officials to negotiate, with a focus on ensuring that workers would not suffer repercussions should they seek to re-enter the United States.

"We are especially grateful for their exceptional efforts... for their meticulous attention to addressing various concerns, including ensuring no disadvantages upon re-entry," the firm said in a statement sent to AFP.

Images of the workers being chained and handcuffed during the raid caused widespread alarm in South Korea, and Seoul said the government had negotiated to make sure the workers were not handcuffed again as they were repatriated.

The raid came less than a month after Trump welcomed Lee to the White House.

The site of the raid is a $4.3 billion venture to build a battery cell manufacturing facility in Georgia.

Many South Korean companies bring their own workforce during project development periods, with industry sources telling AFP it is common practice to use visa workarounds to avoid project delays.

LG said it remained committed to its US projects, adding that it was also working to minimise "any business impact resulting from this incident".
