South Korean workers detained in Hyundai plant raid to be freed and flown home

I’m guessing they were here on a business/consulting visa and doing more than that but it’s probably been de facto practice for years and hasn’t had issues. And I’m guessing the majority of them have skills in setting a factory up that are difficult to source locally.

Yeah, it would take a while to train the locals to speak Korean.

Indeed. Likely just a pragmatic thing here that’s always worked. Will likely end up with a new special kind of very short term visa to cover this sort of thing.
