SEOUL, Sept. 11 (UPI) -- South Korean President Lee Jae Myung said Thursday that last week's "perplexing" immigration raid at a Hyundai electric battery plant in Georgia, which led to the detention of more than 300 South Korean workers, could prevent firms from making future investments in the United States. "Companies will have to worry about whether establishing a local factory in the United States will be subject to all sorts of disadvantages or difficulties," Lee said at a press conference
