USCIS announced multiple measures that aim to further deter and detect H-1B visa fraud and abuse, including a more targeted approach when making site visits to H-1B petitioners and worksites of H-1B employers. USCIS will focus on H-1B-dependent employers, employers petitioning for H-1B workers who work off-site at another company or organization's location, and cases in which it cannot validate the employer's basic business information through commercially available data. USCIS also established an email address dedicated to receiving information about suspected H-1B fraud or abuse, including tips and alleged violations. In related news, DOJ cautioned employers petitioning for H-1B visas not to discriminate against U.S. workers, warning that employers violate the INA if they have a discriminatory hiring preference that favors H-1B visa holders over U.S. workers.
