There are all kinds of Koreans, but to name a few:
American-Koreans (so-called twinkies/bananas)
people who have spent their entire lives in America. Usually US born and second- or third-generation immigrants. They either can't speak Korean at all or understand very little of it; but they do have impeccable English speaking skills and lots of white friends. Most feel uncomfortable around other types of Koreans and/or some older relatives. Very Americanized, with no understanding of Korean tranditions or Korean pop culture. Less intense when it comes to school and work; only few of them tend to show outstanding academic performance. They all have English first names.
include Koreans who came to America as kids or those who have spent many years at American schools. Many have English first names but some choose to keep their Korean names. Good English, but their English speaking abilities depend on the number of years spent in America or the number of American friends they have. Most are academically successful and get straight A's.
