Switzerland does this well. In Switzerland, immigrants are mostly permanent residents. Achieving Swiss citizenship is very difficult. They have a bunch of immigrants in their country, yet immigration is much less divisive than in other countries, since they have such a well-designed system.

The US has a naturalization-driven model of immigration, which is being tested by fast jet travel. It worked OK in the days when you had to pay a bunch to cross the Atlantic and you couldn't easily communicate with your relatives back home. But things are different now.

The citizenship model or naturalization model creates policy implications for accepting immigrants. New voters, new policies. Of course the people on the losing end of this policy shift become upset: https://arctotherium.substack.com/p/increasing-skilled-immig...
