Bangladeshi national admits to running smuggling routes from Brazil to the US border

Saiful Islam, 39, a Bangladeshi national extradited from Brazil in April 2026, has pleaded guilty to his role in an international human smuggling conspiracy, DOJ Justice News reports. Islam admitted to facilitating the illegal movement of migrants through South America, Central America, and Mexico into the United States.

According to court documents, Islam operated within a broad smuggling network, helping move people from and through Brazil, Colombia, and Mexico toward the U.S. border. Some migrants were transported along the Colombian coast in boats piloted by intoxicated operators. Others trekked through the Darien Gap — the treacherous jungle corridor between Colombia and Panama. A number were given falsified documentation belonging to other individuals in order to conceal their identities.

Upon reaching the Southern border, migrants were directed to enter the United States either by wading across the Rio Grande or by climbing over a border fence. Islam charged several migrants thousands of dollars per person for these smuggling services.

Islam pleaded guilty to one count of conspiracy to bring an alien into the United States and two counts of bringing an alien into the United States, all carried out for commercial advantage and private financial gain. As part of his plea agreement, Islam agreed to forfeit money collected from the people he smuggled. Sentencing is scheduled for February 17, 2027. He faces a mandatory minimum of three years in federal prison; a federal district court judge will determine the final sentence based on U.S. Sentencing Guidelines and other statutory factors.

The case was announced by Assistant Attorney General A. Tysen Duva of the Justice Department's Criminal Division and U.S. Attorney Aaron Reitz for the Southern District of Texas.

Homeland Security Investigations (HSI) Phoenix led the investigation, with support from HSI Laredo, HSI Brasilia, HSI Bogota, the HSI Human Smuggling Unit in Washington, D.C., U.S. Customs and Border Protection's Counter Network Division, the Brazil Department of Federal Police, Colombia National Police, the U.S. Marshals Service, and INTERPOL. The Justice Department's Office of International Affairs played a central role in securing Islam's arrest and extradition.

Trial Attorney Spencer M. Perry of the Criminal Division's Human Rights and Special Prosecutions Section and Assistant U.S. Attorney Leslie Cortez for the Southern District of Texas are prosecuting the case.

The prosecution is part of the Joint Task Force Alpha (JTFA), the Justice Department's primary initiative targeting human smuggling and trafficking networks operated by cartels and transnational criminal organizations across the Americas. JTFA, led by the Human Rights and Special Prosecutions Section and conducted in partnership with the Department of Homeland Security, focuses on the most dangerous and wide-reaching smuggling operations affecting public safety and border security. To date, JTFA's work has led to more than 486 arrests of leaders, organizers, and key facilitators of smuggling networks across the United States and abroad, along with more than 447 convictions and more than 374 significant prison sentences and asset forfeitures.
