If an immigrant marries a U.S. citizen, the marriage never gives citizenship, but it's supposed to give instant legal residency, with a green card. After receiving the green card, she needs to wait five years, get a background check, and take the test, to get American citizenship.
Oh the pain and the shame of obeying the law
Deport both of them, both broke immigration law.
I have no sympathy for either of these two.
