Wong Kim Ark v. United States (1898): The Supreme Court ruled that a child born in the United States to Chinese parents was a United States citizen by birth, regardless of the immigration status of the parents. The Court held that the Fourteenth Amendment's birthright citizenship provision applied to all persons born in the United States, regardless of their race or ancestry.
United States v. Bhagat Singh Thind (1923): The Supreme Court ruled that a person of Indian descent could not become a naturalized citizen of the United States because he was not considered to be "white." The Court held that the Naturalization Act of 1790, which limited naturalization to "free white persons," did not include people of Indian descent.
Korematsu v. United States (1944): The Supreme Court upheld the U.S. government's order to forcibly remove and intern Japanese Americans from the West Coast during World War II. The Court held that the order was justified by the government's interest in national security.
Loving v. Virginia (1967): The Supreme Court ruled that laws prohibiting interracial marriage were unconstitutional. The Court held that such laws violated the Equal Protection and Due Process Clauses of the Fourteenth Amendment.
