Yuniel Lima-Santos, a 31-year-old Cuban citizen residing in Tampa, Florida, pleaded guilty on Thursday in a federal court for the Middle District of Florida for his involvement in an international human smuggling conspiracy, asylum fraud, and money laundering, according to a statement from the United States Department of Justice in a news release.
Lima-Santos is one of the 12 defendants in a case that authorities describe as one of the most sophisticated immigration fraud networks documented in South Florida in recent years, active between January 2021 and June 2025.
How did the network work?
The organization operated under the guise of a company called Asesoría y Servicios Migratorios LLC, based in Tampa, which publicly presented itself as a legitimate immigration consulting service.
The accused lured clients through social media and WhatsApp groups - including one named "ESTA APPLICATION AND TOURIST VISA TO THE U.S. FOR SPANISH CITIZENS" - where they offered documents that purported false European citizenships to fraudulently apply for authorizations from the Electronic System for Travel Authorization (ESTA).
Cubans are explicitly excluded from the ESTA program.
To circumvent that restriction, the accused manufactured false European citizenship documents and declared to the authorities that the applicants had not been in Cuba since 2011, knowing that this was false.
The Acting Attorney General A. Tysen Duva of the Criminal Division described it this way:
"They deliberately orchestrated a sophisticated plan to recruit and traffic thousands of Cuban citizens to the United States, illegally obtaining immigration benefits through fraudulent applications, false statements, and illicit financial transactions."
Smuggling services charged between 1,500 and 40,000 dollars per person.
The network even chartered private planes to transport entire groups of migrants and generated over 18 million dollars in total revenue.
The role of Lima-Santos
Within the conspiracy, Lima-Santos was responsible for the logistics of transportation: he purchased international and domestic flights to move migrants from their countries of origin to various locations in the United States.
Between 2021 and 2024, he transferred internationally more than 600,000 dollars to finance those flights.
Along with the co-defendant Frandy Aragon Diaz, he illegally brought five foreigners into the country and admitted to having helped introduce Cuban women who later worked in adult entertainment clubs to pay off their smuggling debts.
To hide the illicit money, Lima-Santos established a shell company in Florida with no employees, payroll, or declared income, used solely to move and disguise the funds from smuggling.
The defendant pleaded guilty to a total of ten charges and faces a maximum sentence of 20 years in prison.
The sentencing date has not yet been scheduled.
Pending convictions and trials
The first to receive a sentence in this case was Erik Ventura-Castro, a 24-year-old Cuban resident in Hialeah.
He pleaded guilty on May 7 and was sentenced on July 29 to 30 months in federal prison.
Ventura-Castro made more than 40 electronic payments to the U.S. Citizenship and Immigration Services (USCIS) to process fraudulent ESTA applications and transferred over $97,000 to the Cayman Islands, Colombia, and Mexico.
Other six defendants -Liannys Yaiselys Vega-Perez, Miguel Alejandro Martinez Vasconcelos, Layra Libertad Treto Santos, Emanuel Martinez Gonzalez, Walbis Pozo-Dutel, and Luis Emmanuel Escalona-Marrero- have already pleaded guilty and await sentencing.
The defendants Lazaro Alain Cabrera-Rodriguez, 28 years old; and Gisleivy Peralta Consuegra, 41 years old, are the only ones who have not yet reached an agreement with the prosecution.
His trial is scheduled to begin on September 21.
