“Through the anonymous social network Blind last spring, Sane heard rumors of people getting registered multiple times, effectively diminishing the chances of those who play by the rules, but figured there was nothing he could do about it. He eventually landed on the mailing list of a group of H-1B seekers exploring a class action suit and a Reddit post that read, “we’re looking to sue @uscis over allowing people to game the system by filing multiple H-1B applications for the same worker.”

Alleging the new system is “rife with fraud and abuse,” an attorney for Sane and hundreds of other disappointed registrants are asking a federal judge to shut it down. Attorneys for the more than 500 plaintiffs in the lawsuit, filed on June 28, on Tuesday filed a motion for a preliminary injunction to put the registration system on hold while they pursue an order to have the rule that created it set aside.

U.S. District Judge Trevor McFadden in Washington will hear arguments over the injunction request on Aug. 27″.
