I worked with a French guy in Amsterdam. His parents were Portuguese, but he was born and raised in France. As far as he was concerned, he was French.
As I understand it, that’s a French thing specifically, not just a non-USian thing. Like, if you’re a citizen of France, you’re expected to be French and assimilate into that culture, no matter whether you’re a native Parisian, you moved there from Algeria in the '60s, or you’re from some random other place and got citizenship via the French Foreign Legion. It’s a specific sort of national ideology that’s different from the American “melting pot” one.

I’ve generally heard the opposite. You can immigrate to France, get citizenship, and be as French as possible, but you will never be French.
