330 Korean workers detained after being arrested on immigration law violation charges at a battery factory construction site in Georgia, USA have returned home. The workers testified that the detention facility conditions were extremely poor and the food was inedible. In particular, they complained about the terrifying arrest process where guns were pointed at them and they were dragged in chains, as well as the anxiety of not knowing when they would be released. The incident has sparked controversy over the unexpected U.S. enforcement measures.
