In one example, an immigrant engaged in a sham marriage with an elderly U.S. citizen and subjected the citizen to "elder abuse and exploitation," according to USCIS. Another immigrant admitted to fabricating a death certificate from Kenya for $100 to falsely claim the termination of a marriage — the spouse in question was alive, living in Minneapolis and the mother of five of his children.
Other cases included a petitioner who confessed to marriage fraud just hours after swearing under oath that her marriage was legitimate, and another involving an immigrant who had overstayed a visa waiver, was the son of a suspected terrorist, and had previously been denied benefits for fraud.
