WASHINGTON: US federal authorities have claimed to have unearthed a major H-1B visa racket with the arrest of at least 11 persons, most of them suspected to be of Indian origin. Though the officials did not reveal the citizenship of those arrested, the names released indicated that almost all of them are either Indian or persons of Indian origin. Vision Systems Group, an IT company headquartered in South Plainfield New Jersey, has been indicted on 10 federal counts including conspiracy and mail fraud charge. Viswa Mandalapu is its CEO and president, according to the information available on the company's website.
