I got curious about Switzerland, so I looked on Wikipedia, which says, "As of 2023, resident foreigners made up 26.3% of Switzerland's population. Most of these (83%) were from European countries. Italy provided the largest single group of foreigners, providing 14.7% of total foreign population, followed closely by Germany (14.0%) . . ."

So, they have a lot of immigrants, but they're clearly giving preference to immigrants from cultural backgrounds very similar to them.
