What this does not mention is that his parents owned a house in America at the time of the case.
Both of them lived in the US.
That was, in my view, significant information which the court considered in the case.
Read they were deported. Haven’t seen why.
Also at that time there was an embargo on Chinese being granted citizenship so the parents has done everything they could under the laws of the time.

“That the said Wong Kim Ark is not entitled to land in the United States, or to be or remain therein, because he does not belong to any of the privileged classes enumerated in any of the acts of Congress, known as the Chinese Exclusion Acts, [*] which would exempt him from the class or classes which are especially excluded from the United States by the provisions of the said acts.”
Chinese Exclusion Act
The Chinese Exclusion Act of 1882 was the first significant law restricting immigration into the United States. Those on the West Coast were especially prone to attribute declining wages and economic ills on the despised Chinese workers. Although the Chinese composed only .002 percent of the nation’s population, Congress passed the exclusion act to placate worker demands and assuage prevalent concerns about maintaining white “racial purity.”
The statute of 1882 suspended Chinese immigration for ten years and declared the Chinese as ineligible for naturalization. Chinese workers already in the country challenged the constitutionality of the discriminatory acts, but their efforts failed.
The act was renewed in 1892 for another ten years, and in 1902 Chinese immigration was made permanently illegal. The legislation proved very effective, and the Chinese population in the United States sharply declined.
