Mason Floyd, Leigh Roadman, and Matt Ruza, with significant support from Lori Stephens, recently obtained complete dismissal of an action against two clients, former owners of an EB-5 Regional Center, in the Southern District of Ohio. Under the EB-5 program, established by Congress, immigrants who invest $500,000 of capital into an approved project, receive conditional permanent resident status in the United States. After two years, if the immigrants have satisfied the program’s conditions, they will obtain their green cards. Plaintiffs, ten Chinese nationals, alleged that Defendants procured their investments through fraud, misrepresentation and deception and sought not less than $5,000,000. The Complaint alleged ten counts against Defendants. The Court dismissed plaintiffs’ federal securities laws claims with prejudice and denied their request to replead. The Court also declined to exercise supplemental jurisdiction over the remaining counts and entered judgment in favor of Defendants.
