However, Joe -- who moved to the United States at the age of 1 but never became a U.S. citizen -- is able to file an appeal until November 9.
"Based upon the law, I find you deportable and ineligible for any kind of relief," Judge John Ellington reportedly said during the hearing. "Mr. Giudice, no matter how this turns out, I wish you the best. I decided this case as a matter of law."
The news reportedly shocked Joe, as he responded to the judge, "I don't understand how I can be deported on this case. If you will, I'll tell you my side. I shouldn't even be here right now. I have to go back and tell my kids this, and they've been waiting to hear from me."
During his prior court hearing on September 1, RadarOnline reported that Joe begged the judge to let him stay in the United States.
"I've been here my whole life, I wouldn't know what to do in any other country," he reportedly told the court. "I want to stay here."
Teresa and Joe, both 46, were sentenced to jail time in October 2014 after pleading guilty to three counts of bankruptcy fraud, and conspiracy to commit mail and wire fraud as part of a plea deal to resolve their 41-count federal fraud indictment.
In June, the married couple's attorney James J. Leonard -- who declined comment on the latest news -- had insisted Joe would not be deported.

"We remain optimistic that when the day comes where a court decides the fate of Mr. Giudice, they will return him home to his wife and four daughters where he belongs," James told Us at the time. "But that is for a judge to decide."
Teresa and Joe, who wed in 1999, share daughters Gia, 17, Gabriella, 14, Milania, 12, and Audriana, 9.
While Teresa said on the Season 8 reunion special of The Real Housewives of New Jersey in January she "wouldn't mind" moving to Italy with her husband if he's deported because it's "a beautiful place to live," TMZ reported she will not move to Italy and uproot her children.
