Having working in US immigration, most reporting on immigration issues leaves a lot to be desired.

Because of the poor reporting, it's not possible to say for sure what happened, but it sounds like Hyundai/LG/subcontractors brought in hundreds of South Koreans on B visas and had them engaging in productive work. That's not what B visas are for. B visas are for meetings, sales, and maybe some light training/setup/integration. When the CEO talks about needing specialized, skilled workers, that's a strong suggestion these workers should have been on L visas.

Times reporting confirmed a few of the workers were on B visas: https://www.nytimes.com/2025/09/12/business/economy/hyundai-...

Unfortunately the same article doesn't even mention the L visa, and cites an immigration lawyer who complains about the difficulty of getting H-1B visas. But L visas are not capped like H-1Bs. In India we approved thousands of L visas specifically for skilled workers to assist with bringing plants/equipment online.

In short, the B visa is not a work visa. Most countries worldwide are quite restrictive about the conditions surrounding work visas, and people who violate the conditions of their visa shouldn't be surprised when there are consequences. Having a valid visa but violating its conditions means you are violating immigration law.

Corporate immigration departments can and do cut corners and may have thought they would save money and time by sending foreign workers on B visas (which they might have already had) or on the visa waiver program. L visa holders don't even have to get paid US-level wages, so one take on the visa type is that it is already a way for companies to undercut US labor.

> and maybe some light training/setup/integration.

What do you mean by "maybe" or "light"? That's an explicitly permitted activity:

> 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.

https://es.usembassy.gov/visas/commercial-industrial-workers...

Modern factories are filled with machines the size of buildings, making that installation sometimes hard to distinguish from the forbidden "construction". It's possible that some of those Koreans were unequivocally on the bad side of the line, but I see zero possibility that the agents could have meaningfully assessed that in the time between beginning the raid and taking the workers away in shackles.

I feel like installing equipment is widely considered to be an illegitimate use of B-1 visas, despite this explicit guidance. I don't understand why. I see from your comment history that you were a US diplomat. Is the internal guidance you received different from what's published?

Like anything in law, it depends on the details, context, case law, and possibly future litigation.

CPB's Q&A on permissible B-1 visa activities (PDF): https://www.cbp.gov/sites/default/files/documents/B-1%20perm...

"If the contract of sale specifically requires the seller to provide these services or training, and you possess specialized knowledge essential to the seller's contractual obligation to perform the services or training it may be permissible for you to perform these services. In addition, the machinery or equipment must have been manufactured at a location outside of the United States and you may not receive compensation from a U.S. source."

Given how vague the reporting has been, we don't know basic facts like what the workers were doing, what the agents saw, what types of visas they were on, etc.

This PBS article quotes a local labor union leader who claims "unions that are part of her council believe Korean workers have been pouring cement, erecting steel, performing carpentry and fitting pipes." https://www.pbs.org/newshour/nation/attorney-says-detained-k...

Obivously the person quoted has an agenda and didn't actually witness those activities - so we just don't know. That being said, if that description is accurate, in general that kind of activity would not be appropriate on a B-1 visa and wouldn't qualify for an L visa.

But again, it depends on the details. Maybe the cement base is some special blend for certain equipment, maybe "erecting steel" involves highly specialized welding techniques, maybe this pipe fitting involves specialized high-pressure ratings outside the norm.

When I was a diplomat, our internal guidance (at least, what I was privy to) was never different from public information, just more detailed.

I'd be suprised if the corporate immigration departments of Hyundai or LG messed up this badly. But I wouldn't at all be surprised if some no-name subcontractor decided to play fast and loose with the visa rules to win a contract with a low bid.

> But I wouldn't at all be surprised if some no-name subcontractor decided to play fast and loose with the visa rules to win a contract with a low bid.

I feel like "subcontractor" here could mean "staffing agency used by Hyundai to shed liability", but could also mean "equipment vendor". The latter seems much less likely to be noncompliant, since they get the special benefit of the policy we're discussing and since customer-site labor is a smaller share of their cost (since their primary business is building the machines in Korea).

A lawyer for some equipment vendor staff seems to be alleging that their B-1 applications had been drafted specifically to comply with this policy:

> Kuck said letters included with visa applications that he reviewed spelled out the scope of the work and appeared to meet requirements.

> "It was more detailed than some of the letters that I've written for clients in similar situations," he said. "The vast majority of folks, including the ones I represent, should never have been detained."

https://www.reuters.com/business/retail-consumer/lawyer-says...

I guess it's likely that at least one person detained was unlawfully present, and at least one person detained was lawfully present. The actual ratio is still unknown, but the reputational damage is done--"we took you away in chains, imprisoned you for a week, and deported you, but that's okay because a different worker at your site was noncompliant" is not a great message.

		I don't find the claims made by an immigration lawyer representing the workers to be particularly persuasive, just like I don't find the claims made by the local union rep about what they "believe" the workers were doing to be persuasive. People and companies can and do write whatever they want in letters submitted with visa applications. That has no bearing 1) on what you are actually allowed to do given a certain visa type, and 2) what the worker actually ends up doing. In other words, the visa applications may very well have been valid and approved on that basis, but the applicants might have been engaging in other activities that were not permissible. This is quite common - people will say "I want to go to Disneyworld" when they actually intend to overstay their visa, or "I want to visit family" when they actually intend to work as a nanny or cook for a few months, then return home. I'm not saying this raid was conducted properly or that all the arrests were justified, but I do think the reporting on it has been almost negligent. In contrast, here is an old article written by an immigration lawyer discussing the complexities of the B-1 business visa: https://blog.cyrusmehta.com/2016/05/the-b-1-visa-trap-for-th...

Probably, I doubt anyone in the US government has a consistent view of what immigration laws are _and_ how they're actually enforced. Whole thing feels like a giant slapdash of things thrown together and assessed in whatever way feels right that day.

Here's a fun one: do people born in Hong Kong count as being born in China for green card purposes? Used to be no, then Trump 1 said "yes" with an executive order, then as best I can tell no one in government really enforced that, then immigration lawyers tell me they're counted as rest of world instead of China, and now? Who the hell knows, whoever gets your case probably makes up what they feel is the law.

So the US government does a dog and pony show of ASMR chaining and perp walking Korean engineers constructing a factory vital to our economy and national security?

And this after the admin starts a tariff war against treaty allies for not building factories in the US? Very schizo.

This whole situation is complete insanity and is completely the fault of this administration and the maga movement.

		It’s also the fault of the last administration, because when you bend the rules and your reign ends, you have no control over how the next regime is going to enforce the law as it stands. I do not disagree this is insanity, but this is the result of kicking the can on immigration issues for almost two decades. Congress must do its job, but refuses to. Is it not reasonable to both incentivize domestic manufacturing investment while also adhering to immigration visa regulations? Hyundai has done something similar with children refugees from Central America previously in 2022. https://en.wikipedia.org/wiki/Hyundai_Alabama_child_labor_al...

The reporting is light on what these workers are actually doing. Real construction work like pouring concrete is certainly unacceptable on a B visa. But as you have said B visas are fine for light training/setup/integration. It seems to me that these people are actually just setting up the plant by configuring new machinery.
