Yup, I'm from India, and I'm now considered "firaang" (foreigner) — even my own people won't fully accept me! "ABCD" is an acceptable pejorative, because the culture is by and for the people that were born and raised in India, and they won't have it any other way.

In America, as long as you're a hard worker, believe in America's institutions, and are civically engaged, it doesn't matter where you're from, you will eventually be accepted as "American", and if anyone were to suggest otherwise, they'd likely get ostracized by most (if not all) institutions that hold power/influence.
