In just the past two months, the San Juan office of the Homeland Security Investigations (HSI) agency has arrested eight people for entering into sham marriages to obtain legal residency in Puerto Rico. Since January 2025, it has also received more than 100 referrals from the U.S. Citizenship and Immigration Services (USCIS) to launch additional criminal investigations into couples who may have engaged in marriage fraud, a felony punishable by up to five years in prison.
