In practice, the Cable Act of 1922 reversed some racial exclusions, and granted independent woman citizenship exclusively to women married to white men. Analogously, the Cable Act allowed the government to revoke the citizenship of an American white woman married an Asian man. The law was formally challenged before the Supreme Court, with the case of Takao Ozawa v. United States (1922), whereby a Japanese American man tried to demonstrate that the Japanese people are a white race eligible for naturalized American citizenship. The Court ruled that the Japanese are not white people; two years later, the National Origins Quota of 1924 specifically excluded the Japanese from entering the US and from American citizenship.
