Joe is serving a 41-month prison sentence after pleading guilty to fraud with Teresa in 2014.
He is expected to appeal a judge's decision to deport him to Italy at the end of his sentence.
Teresa, who is also parent to daughters Gabriella and Audriana with Joe, broke her silence on her husband's deportation ruling Sunday on Instagram.
She shared a photo of the Statue of Liberty covering her face with her hands.
E! News said last week Teresa is "devastated" by Joe's deportation order.
