I’m Korean and I’ve been wondering how differently people can retain their first language after moving to an English-speaking country.
I have an older Korean friend who moved from Korea to Sydney at 9. He’s 27 now, has barely been back to Korea since, did almost all of his schooling here, went to university here and now works here. His parents stayed in Korea and his grandmother looked after him to some extent, so he didn’t grow up with Korean-speaking parents constantly using Korean at home. Almost all of his close friends growing up were white too, so he wasn’t really in an Asian social bubble.
English is more comfortable for him and he’s completely native in it, yet his Korean is extremely natural. I’ve known him for over 5 years and we basically only speak Korean. Korean probably became our default because my English wasn’t as good when we first met, but my English is completely fine now and we still almost never switch. His Korean was already very natural when I met him around 2020, and he says dating Korean girlfriends since then has improved it even more.
What’s interesting is how different other cases I’ve seen are.
I knew another Korean guy who moved to Australia at around 11-12, and by high school English was already his dominant language and his Korean was noticeably awkward.
Another friend’s older brother moved to the US at around 17. He was already extremely good at English in Korea, had even competed in international English-speaking competitions and had visited the US several times before moving. After he’d been there for a while, even his dad noticed over video calls that his Korean had become less natural and joked with him about it. English is now much more comfortable for him and he’s settled in the US.
So he left Korea much later than my friend who moved at 9, yet their outcomes seem almost reversed.
I also knew a Chinese guy who moved to Australia at 9 whose Mandarin still sounded completely mainland native, but he told me that culturally he felt like his understanding of China was basically stuck at age 9. That also made me wonder how separately language and cultural familiarity can develop.
I came to Australia myself at around 15-16. My English is completely fine now, but Korean is still overwhelmingly more comfortable for me for speaking, reading and writing, and culturally I still feel much more Korean.
So what causes outcomes this different? How much is age of immigration compared with family language, peer groups, relationships, media exposure, personality or individual differences in language retention? I’d especially like to hear from people who moved during late childhood or adolescence, or parents who have seen very different outcomes between siblings.
