MUSKOGEE, OKLAHOMA - The United States Attorney's Office for the Eastern District of Oklahoma announced that Celso Martinez-Mata, a/k/a Celso Mata Martinez, a/k/a Celso Martinez, age 60, a Mexican national unlawfully present in Sequoyah County, Oklahoma, was sentenced to time served for one count of Unlawful Reentry of Removed Alien.
The charge arose from an investigation by the U.S. Department of Homeland Security's Immigration and Customs Enforcement Division and the Oklahoma Highway Patrol.
On December 22, 2025, Martinez-Mata pleaded guilty to the charge in federal district court. According to investigators, on October 29, 2025, Martinez-Mata, an alien, was found in the United States without obtaining the express consent of the Secretary of Homeland Security to reapply for admission to the United States after having been previously removed on July 2, 2002.
This case is part of Operation Take Back America, a nationwide initiative that marshals the full resources of the Department of Justice to repel the invasion of illegal immigration, achieve the total elimination of cartels and transnational criminal organizations (TCOs), and protect our communities from the perpetrators of violent crime.
The Honorable Raúl M. Arias-Marxuach, Chief Judge in the United States District Court for the District of Puerto Rico, sitting by assignment, presided over the hearing.
Special Assistant U.S. Attorney Olivia Staubus represented the United States.
