<h1>South Korea arranges charter to repatriate workers after U.S. immigration raid; seeks assurances on restraints and reentry</h1> A South Korean government-chartered flight was arranged to repatriate hundreds of workers detained in a large U.S. immigration raid at a battery plant construction site operated by a South Korean joint venture; departure was delayed pending U.S. coordination. Allegations include use of restraints during arrests and detentions at a Georgia immigration facility. Seoul negotiated voluntary departures to avoid formal deportations that could trigger multi-year reentry bans; it seeks assurances against handcuffing and obstacles to future U.S. entry. Officials proposed a bilateral working group and new visa category for skilled Korean workers; U.S. authorities say detainees included individuals with expired or inadmissible visas or illegal entry.
