Seoul said Sunday that negotiations with the United States to secure the release of South Korean workers detained in an immigration raid have ¡°concluded¡± and they would soon be freed and flown home.

The announcement follows the arrest of more than 300 South Korean workers at a Hyundai-LG battery plant being built in the southern state of Georgia on Thursday.

The operation, carried out in the town of Ellabell, was the largest single-site raid implemented so far under U.S. President Donald Trump¡¯s nationwide anti-migrant drive and caught Seoul officials off-guard.
