<h1>Charter plane readies to repatriate hundreds after mass immigration raid at construction site; departure timing remains uncertain</h1> A foreign charter plane arrived to repatriate dozens of detained foreign workers after a large immigration raid at a battery plant construction site, but departure timing remained uncertain as officials negotiated releases. About 475 workers were arrested; many face claims of illegal entry, visa overstays, or use of visa waivers prohibiting work. Authorities are seeking voluntary departures to avoid formal deportation bars that could deny re-entry for up to 10 years. Detainees are held at an immigration facility pending transfer to the charter. Governments are pressing for visa-rule changes and possible legislative quotas to accommodate specialized foreign labor; legal counsel notes some onsite skills are unavailable domestically.
