<h1>Immigration authorities release 330 foreign construction workers after raid; detainees flown home amid diplomatic and trade tensions</h1> US immigration authorities released 330 foreign workers, mostly from South Korea, who had been detained at a battery factory construction site in Georgia; the workers were bused to Atlanta to catch a charter flight back to their home country. The detentions followed an immigration raid at the construction site on Sept. 4, prompting diplomatic attention from the workers' government. The incident occurred amid high-level economic negotiations between the two countries, including large proposed investments and tariff discussions, and has generated public and governmental concern over enforcement actions affecting international labor and diplomatic relations.
