Agree with your first two paragraphs, disagree with the last.

> If foreign researchers are able to prove themselves abroad and contribute as you say, I assume they can continue doing that in most cases without coming to the US to take jobs.

They can't prove themselves abroad. Consider the example of "Attention is all you need" paper. That paper came into existence thanks to talented people from around the world coming together in one place and then collaborating. It would not have happened if the contributors stayed in their own countries.

> If immigrants are such a great resource, why are poor countries not trying harder to keep those people from leaving?

They are. See here: https://www.reuters.com/world/asia-pacific/china-restricts-o...

> Why doesn't China import a bunch of Indians for IT work, or vice versa?

They are trying. See here: https://www.nytimes.com/2025/10/14/world/asia/china-stem-vis...

I think this is a stretch, especially now that we have the internet. I also wouldn't be opposed to non-immigrant research visas, perhaps a specialized type of H1-B visa (since most of these people are not independently wealthy). But what I don't want is any random foreigner who has their name on some academic papers to be considered top talent. There are paper mills that crank these people out (putting their names on papers without any involvement), and besides that most research is just not that good. Why would we want a bunch of mediocre foreign researchers to come and take jobs away from mediocre American researchers? As we know, getting jobs in academia is very difficult as-is.

You got me on China trying to stop talent from leaving. It's an authoritarian country though. You can't even travel around freely inside the country lol! I threw China in there because a lot of H1-Bs and students are actually Chinese, but China is not where most of them come from.

You also got me on China allegedly trying to get talent to move to China. Their people seem to have had a predictable reaction. That's really something, considering that they can get in trouble for criticizing their government. I guess they thought it was worth the risk, because doing nothing would screw them even harder.

We disagree on your first paragraph, agree on the rest.

		I'm surprised you can't find something to agree with in the first paragraph. I feel compelled to restate and clarify points I glossed over, to see which one you disagree with: 1. Foreign researchers can communicate with colleagues fairly well over the internet (in real time, even). Physical presence is not required to do academic research, at least in mathematics or CS. 2. Degree mills, fake credentials, paper mills, etc. exist to get names on stuff for a fee. This is used to game the immigration system. 3. Many US degree programs are used as a vector for immigration more than education, and people who immigrate this way usually try to meet the minimum requirements to stay in the US and do little beyond that. 4. Even when it comes to research, most research just isn't that good and doesn't contribute that much to society. 5. Getting jobs in academia is difficult. 6. Immigration lowers wages due to the basic laws of economics. 7. Given the fact that we have mediocre researchers in abundance, such that they can't find work in academia, there is negligible societal benefit to importing mediocre foreign researchers en masse. Additionally, this is devastating to the local labor market. 8. All other things equal (to the extent it is reasonable to determine), a country should try to ensure that native citizens get priority in hiring, rather than importing replacements. If you disagree with #8, perhaps you should consider who is going to be willing to spill their blood and give up their treasure to defend a country that undermines them at every turn.
