I took some minutes to try and find statistics, and also ChatGPT claims that the EU simply doesn't collect or publish that kind of data, so I'm wondering how you think you know.
All I see in my circle is people refusing to even go on vacation in the US, let alone move there.

"Between January and July 2025, just under 780,000 German tourists flew to the US, around 12% fewer than the same period in the previous year. [...] People are also deterred by plans to require foreign tourists entering the US to share five years of their social media history, as well as reports of Germans suddenly finding themselves in detention or being deported. The number of applications for student exchanges in the US fell significantly last year with some media reports speaking of a 50% decline." https://www.dw.com/en/threat-to-world-peace-how-germans-see-...
I do know people who've gone, only on vacation and they were exactly the sort of unthreatening rich white folks that you'd expect to have least trouble. Oh, and some US citizens who went "home" to see family at Xmas but work here.
