It would be better to spend less of your comments expressing frustration with people who don't understand, and more explaining what the difference actually is. I read both of your comments and while I have no reason to disagree with you, I can't tell what you're actually saying.
If you respond to incorrect information with correct information and show us how it is correct, your comments will be more persuasive as well as more in the intended spirit of the site (https://news.ycombinator.com/newsguidelines.html).
It can be easy to take this for granted when you already have the correct information mapped out in your head many times over—but the rest of us don't have access to that!
Fair, I will do that. I had just become jaded over the years(almost 15 years now) spending time explaining the same point in tech forums and then later it's just even more and more comments from others confidently stating the same wrong things again on every tech immigration related story(a bunch on this story including the couple of parent comments in this thread I was replying to). This creates a feedback loop with others assuming the same.
For a while I did not engage with such stories because it feels like a losing battle swimming against the current even though tech forums are generally filled with smart folks.
As another sibling comment said, the requirements for placing ads etc. are for the first step of the green card process, aka PERM, and are not required for a H1B visa.
Maybe I should write a blog post or something explaining it and link it every time :)
Having posted over 60k comments largely repeating the same explanations over and over, I definitely sympathize with the frustrations of internet statelessness!
Writing one definitive explanation and then linking to it sounds like a good solution in this case. Even if just you wrote it up as an HN comment and then linked to that in the future.
