anecdotal but every asian kid ive known that was born and raised here didnt have an asian accent.And I grew up around alot of asians.
but if you wanna run with the narrative that asians born and raised in america probably have an asian accent. Then so be it, but that shit lowkey racist imo.
It's case by case. Some immigrant parents are adamant that their kids learning English or kicking their accents and some don't see it as an issue.
