This seems helpful, but I think the misattribution of a general "anti-immigrant" sentiment to immigration detractors is part of the problem.
Very few detractors in the west have any issues with highly qualified immigrants occupying scientific or research roles. Being opportunistic with which kind of immigrants one offers as Good is partly what's aggravating the issue. It's a radical kind of dismissiveness and denialism which is provoking people and ignoring their issues.
The broad western detraction against immigration at the moment is targeted at specific waves of mass immigration with specific compositions that have specific effects on the places those immigrants have landed.
People are primarily concerned about the ability of state, social and corporate institutions to absorb immigrants at this pace and scale without significant zero-sum effects. And, in addition, the significant amount of state support segments of those populations (eg., esp. asylum seekers) have to receive at a time when gov. are under inflationary pressures, debt pressures, etc. and cannot service their own welfare obligations.
Going, "oh but we get good cancer research from immigration!" is so dismissive to these concerns, that the backfire against this messaging is one of the major contributors to people's disaffection.
The idea that people need to be told that there are people who want to immigrate that are in our national interest to absorb, is just plainly absurd. This is uncontroversial and obvious.
