This article from Diversity Executive states that different generations of immigrants from Korea had different experiences, largely due to the reasons for the immigration.
Earlier immigrant waves followed the more traditional "work hard to build a new life" paradigm, dealing with a lot of racism while they were trying to gain a foothold. Later immigrant waves were more likely to come from wealthier families, seeking a US college education and more opportunity. Not necessarily looking for a "better life."
My immigration story is adoption into white middle class, but my (white) grandparents' generation maps to the earlier immigrant waves. Comment below--does your family's experience map to the article? Or did the author get it wrong?
