The State Department said on Friday that 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 Trump administration has offered the 317 South Korean workers who were detained in the raid the chance to return to the plant in Ellabell, Ga. 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. The State Department has encouraged those who were previously in Georgia on a visa waiver program to apply for B-1 short-term business visas and has issued new guidance on the activities allowed under them.

The State Department said on Friday that it had added the capacity last month to conduct more than 5,000 interviews above normal levels. It said it was implementing President Trump’s “commitment to U.S. reindustrialization by facilitating legitimate business travel, including additional consular resources for visas supporting South Korean investments in the United States, while maintaining the highest standards of national security.”

The State Department did not specify the period over which those extra interviews would be conducted or how many interviews it typically conducts. It also did not say how many additional staff were tasked with processing business visa applications from South Koreans.
