OP here. As the meme goes, I am one of literally dozens of people who live outside the USA.

"Immigration" is the commonly used term in the UK. See https://www.parallelparliament.co.uk/question/99775/eurostar... and https://www.heathrow.com/arrivals/immigration-and-passports

Similarly, Australia uses the term if you want to apply for a visitor's visa - https://immi.homeaffairs.gov.au/visas/

You'll also notice that the original report was written by an EU group.

Ok, thanks for setting the record straight, I stand corrected. Interestingly enough, while I have been to the UK several times, I don't remember coming across the term "immigration" (probably because most of those times were pre-Brexit, so immigration was much less of a hassle for a EU citizen than it would have been when visiting the US).
