Im going to be honest here and say America. Ironically I am an immigrant who came here as a kid, but I do feel more American than even my original ethnicity. But it also depends where Im at, and in the US i feel less American in a way. Obviously traveling the US I will identify with NJ more, but if youve been to other parts of the world, youll see how homogenous the US really is. Its pretty much all suburbs everywhere whether its NJ, Florida, or Arizona, it feels VERY similar (compared to other countries obviously). But I will admit when I do travel I always only tell people I am from NYC/NJ (code word for "I work in city but live in NJ") so theres that.
