> 5:10 "475 were illegally present in the United States"
Not quite; The figure includes those with visa.
"Illegally present in the United States or in violation of their presence in the united states, working unlawfully"
This also leaves open the question of what "violation of the visa" entails here. They may well have been working within their visas, only for ICE to arbitrarily rule otherwise.
It gets a little confusing because ESTA(which South Koreans are eligible for) is valid for both tourist and business use, and is a visa waiver.
As this comment[1] states with an official source:
> A B-1 visa may be granted to specialized workers going to the United States to install, service, or repair commercial or industrial equipment or machinery purchased from a company outside of the United States, or to train U.S. workers to perform such services.
Maybe the business use of ESTA also covers the above use cases?
