On August 13, 2026, authorities announced that Yuniel Lima-Santos, 31, pleaded guilty to federal charges tied to an international alien smuggling ring that used fraudulent visa-waiver applications, moved people into the United States for profit, and laundered proceeds through a shell company.
Federal filings describe an organized alien smuggling organization that targeted Cuban nationals and others, encouraging thousands to try to enter the United States through the southern border. The scheme used fraudulent Electronic System for Travel Authorization, or ESTA, submissions and false claims of European citizenship to get people onto flights and into the country.
Investigators say the group advertised smuggling and fake visa services across multiple social media platforms and filed hundreds of fraudulent ESTA applications with U.S. Customs and Border Protection using fake addresses and fabricated documents. Cuban nationals are not eligible for the ESTA program, and the defendants repeatedly represented that applicants had not been in Cuba since 2011 despite knowing that many were in Cuba when the applications were submitted.
Yuniel Lima-Santos, based in Tampa, Florida, admitted he helped move aliens from their countries of origin into the United States by purchasing international and domestic flights and arranging transportation. He and co-defendant Frandy Aragon Diaz are accused of smuggling five aliens into the United States, and Lima-Santos acknowledged aiding Aragon Diaz in bringing Cuban women who then worked in strip clubs to pay off smuggling debts.
Documents show Lima-Santos set up a Florida shell company with articles of incorporation despite it having no employees, payroll, or reported income; prosecutors say the company was used to move and conceal proceeds from the smuggling operation. Aliens paid between $1,500 and $40,000 for smuggling services, and co-conspirators sometimes chartered private planes to move groups of aliens.
Between 2021 and 2024, Lima-Santos allegedly transmitted internationally more than $600,000 from the United States to buy flights and facilitate unlawful entry for aliens. The prosecution says funds were regularly funneled to companies and other destinations outside the United States to hide the source and nature of the money.
Yuniel Lima-Santos pleaded guilty to one count of conspiracy to commit alien smuggling for financial gain, five counts of alien smuggling for financial gain, one count of conspiracy to defraud the United States, one count of conspiracy to launder monetary instruments, and one count of conspiracy to conceal money laundering instruments. He faces a statutory maximum penalty of 20 years in prison, with a sentencing hearing to be scheduled later; a federal judge will set the sentence after considering the U.S. Sentencing Guidelines and statutory factors.
The superseding indictment named 12 individuals in total. Liannys Yaiselys Vega-Perez, 31; Miguel Alejandro Martinez Vasconcelos, 31; Layra Libertad Treto Santos, 30; Emanuel Martinez Gonzalez, 29; Walbis Pozo-Dutel, 31; and Luis Emmanuel Escalona-Marrero, 32 have pleaded guilty and await sentencing. Erik Ventura-Castro, 24, pleaded guilty on May 7 and was sentenced in July to 30 months in prison. Lazaro Alain Cabrera-Rodriguez, 28, and Gisleivy Peralta Consuegra, 41 are awaiting trial set to begin on Sept. 21.
Senior officials announced the case, including Assistant Attorney General A. Tysen Duva of the Department of Justice’s Criminal Division, U.S. Attorney Gregory W. Kehoe for the Middle District of Florida, Special Agent in Charge Nicholas Ingegno for U.S. Immigration and Customs Enforcement Homeland Security Investigations, and Director Joseph Edlow of U.S. Citizenship and Immigration Services. The investigation was supported and prosecuted by Joint Task Force Alpha, the Department’s lead effort against high-impact human smuggling and trafficking committed by cartels and Transnational Criminal Organizations.
Joint Task Force Alpha coordinates prosecutors and investigators across multiple districts and agencies, supported by the Criminal Division’s Human Rights and Special Prosecutions Section and other DOJ components. According to officials, JTFA’s efforts have resulted in more than 477 domestic and international arrests, more than 431 U.S. convictions, and more than 370 significant jail sentences and forfeitures of substantial assets.
U.S. investigative effort on this matter was led by HSI Tampa, U.S. Border Patrol Miami Sector, and USCIS’s Fraud Detection and National Security office, with assistance from HSI’s Human Smuggling Unit in Washington, D.C., and CBP’s National Targeting Center International Interdiction Task Force. Authorities in the Cayman Islands also provided assistance as the case developed.
