In 1965, American President Lyndon Johnson signed the Hart-Celler Act which overturned the Johnson-Reed or Immigration Act of 1924. The new legislation brought to an end the existence of racial quotas, as well as the exclusion of Asians in the US.
One of the principal beneficiaries of this new legislation were middle-class, well-educated Indians. They moved to the US in droves and swiftly assimilated themselves into American society. There had, of course, been an exodus of Sikhs from India to California’s Central Valley in the late 18th and early 19th centuries. They were extremely industrious and worked as farmers while confronting widespread racial animus.
Over time, subsequent generations of Sikhs became prosperous and even made a mark in national politics. Dalip Singh Saund, who had migrated from Punjab, had worked as a farmer, and later educated at the University of California, Berkeley. He became the first Indian-American to serve in the US House of Representatives. His tenure in office lasted from 1957 to 1963.
