Can Asians born in the United States speak English naturally?

Let me tell you a personal experience. When I was studying in the United States, I rented a house for immigrants from China. The landlord's youngest son is five years old and can't speak a word of English. And he can't speak Mandarin, only Hubei dialect, because the children stay at home all the time and their parents are from Hubei!

Therefore, what a child will say mainly depends on what the people who have been with him say when he learns to speak.

Don't lose heart, I continued: the child's sister, who has been in high school in the United States, speaks standard English! My sister came to the United States from China at the age of seven, and my brother was born in the United States!

So the language environment is also very important. Generally, people who enter the English world before the age of eleven can speak standard English.
