SEOUL, South Korea — The State Department said Friday it had ramped up its capacity at the U.S. Embassy in Seoul to process more business visas for South Koreans, as the Trump administration tries to repair the damage from an immigration raid on a large South Korean-run factory in Georgia.

That operation in September was once lauded by immigration officials as the largest workplace raid in U.S. history. But the images of people in handcuffs and shackles set off anger in South Korea, where officials said that it was a violation of the workers’ rights and that the raid would discourage companies from investing in the United States.

The Donald Trump administration has offered the 317 South Korean workers who were detained in the raid the chance to return to the plant in Ellabell, Georgia. They flew home in September but some later returned to the factory, a battery plant owned jointly by Hyundai Motor Group, one of the world’s biggest carmakers, and LG Energy Solution, after the State Department reissued their visas.

Many of the former detainees have applied for new visas.
