Vimal Patel was studying for a master's in business administration in London when he saw an advertisement for work in the U.S. The ad offered a job in the tech industry, as well as sponsorship for the kind of work visa that allows foreign nationals to take professional-level jobs in the country. So Patel applied and paid his prospective employer, Cygate Software & Consulting, in Edison, N.J., thousands of dollars in up-front fees. But when Patel arrived, Cygate had no tech job for him. He ended up working at a gas station, and Cygate nevertheless took a chunk of his wages for years, according to documents in a criminal case against Cygate.
