I suspect it's due to my mobile operator doing traffic shaping / QoS that deprioritizes UDP VPN.
In contrast, connecting to OpenVPN over TCP was a huge improvement. Not at all what I expected.
In my humble opinion, they are significantly better than pounding a nail into drywall. Of course, I also have an absurdly large collection of framed photographs and other art, all of varying sizes, and I love swapping frames around throughout my home. Having picture rails throughout my house means I don't have to keep pounding holes in the wall every time I replace that 20x20" photograph of my toddler shot in a square aspect ratio with a 16x20 shot on my 4x5, or whatever.
This is way better than arguing with partner about the proper height, making a destructive hole, then having to cover/patch when opinions or artwork change. My walls are not drywall, so that was a big factor, but the freedom to arrange/rearrange is a major benefit.
There's also a EU law which says that users should be able to bring their own modems / routers, so AFAIK providers say that this particular terminal device is still "on their side of the network".
I've seen such devices come in two varieties.
One is a separate device which plugs on the optical network, does the encryption and stuff, and then exposes an ethernet port which is connected to the actual router which does wifi, etc. With SFR and Bouygues, it was trivial [0] to replace the ISP-provided router with one of your choosing. You get the normal external IPs and you do your thing. The ISP router sleeps in its box in storage. This was my setup up until a few years ago, with both these providers. Now SFR has moved to CGNAT, but the setup is the same, so I expect users to still be able to switch routers (but I haven't tested, since I'm not a client anymore).
Then there's Free, who provides a single device that connects to the fiber, does routing, wifi, etc. In this case, it's possible to flip a switch in its settings for it to act as a bridge (don't know how wifi behaves in this case, if it stays on). It then only accepts a single downstream client, which gets the external IP. SFR had a similar setup for DOCSIS.
I'm not familiar with how Orange, the biggest operator, functions. But I understand they have a general tendency to be a PITA so YMMV with them.

[0] For Bouygues, this device only talked on a tagged VLAN100 for some reason. On the SFR, the network expected you to send a client id in the DHCP request.
My connection has been very reliable since ditching the SFR box. My own router plugs into the separate ONT.
SFR also offers good IPv6 support.
Is it really as kafkaesque as you state? You have to enumerate your planned activities in order to get a visa, but receiving said visa is in no way an affirmation that the enumerated activities are legal to perform? That sounds completely dysfunctional to me.
A US visa is simply permission to present yourself at a port of entry for admission, at which time you may questioned further by border control, and in rare cases denied entry.
Most B visas are valid for multiple entries over 10 years. The fact that you wrote a letter and brought it to your original visa interview (which may have been years ago, and likely wasn't even looked at by the officer, who in a busy consulate has less than 2 minutes to complete your interview) does not mean the US government has affirmatively granted you permisison to do everything on that letter.
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.
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...
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?
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.
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.
I’m American and every visa I’ve had to apply for did not require my physical presence at the embassy and I used a third-party processing service to get everything done.
Therefore, while I would need to apply to these countries from their US embassy because my physical presence was not required, I would generally not need to return to the United States to obtain their visa?
And this aspect of a US visa does make it significantly harder even though the application policy is similar to other countries?
That said, back in the 2000s I had to apply in person at the French embassy for a student visa, in in the 2010s I had to apply in person at a Chilean consulate for a special visa.
Many countries have outsourced the bulk of their processing to contractors like VFS or TLS these days. But also, our experience as Americans is not representative as we generally have fewer visas we need to bother obtaining, and face less scrutiny when doing so.
I'm not sure if the US interview requirement makes it "harder" to get a US visa - it may be that getting a US visa is just harder than getting another country's visa, which might still be true even if we didn't interview people. The big thing that makes getting non-immigrant visas to the US difficult for many people is that, unless shown otherwise, US immigration law assumes you are an immigrant.
