In 1893, Virachand Gandhi became the first Jain delegate to visit the United States, representing Jainism in the first ever Parliament of World Religions. As the first practicing Jain to speak publicly in the United States on Jainism, he is a key figure in the history of American Jainism. The first St. Louis Jain temple in the United States was built for the St. Louis World's Fair in 1904. After the fair, the temple moved to Las Vegas and later to Los Angeles. It is now owned by the Jain Center of Southern California. Adherents of Jainism first arrived in the United States in 1944. Jain immigration began in earnest in the late 1960s after the passage of the Immigration Act of 1965. The United States has since become a center of the Jain diaspora.
