Teresa and Guiseppe "Joe" Giudice appeared in a Newark federal court. The couple is accused of exaggerating their income while applying for loans before their show debuted in 2009, then hiding their fortunes in a bankruptcy filing after their first season aired.
Neither defendant spoke before, during or after the five-minute court proceeding, and their pleas were entered by their attorneys.
They were charged last month with conspiracy to commit mail and wire fraud, bank fraud, making false statements on loan applications and bankruptcy fraud.
Both face hundreds of years in prison and millions of dollars in fines if convicted. Joe Giudice is an Italian citizen and could be deported if convicted, prosecutors said two weeks ago. Feinstein said Wednesday his client came to the U.S. as a 2-year-old and wasn't aware that he wasn't an American citizen.
A trial date has been set for Oct. 8, but attorney Henry Klingeman, representing Teresa Giudice, said he expected the trial to be pushed back into 2014 due to the number of charges and complex nature of the case.
The two were required to surrender their passports, and their travel was restricted to New Jersey and New York.
