Brazil Extradites Bangladeshi Man to Texas Over Years-Long Human Smuggling Ring

A Bangladeshi national accused of running a years-long human smuggling operation is now in a Texas courtroom after Brazil finally extradited him to the United States.

Saifullah Al-Mamun, 39, was extradited from Brazil on July 8 and appeared before a federal court in Texas that same week, according to the U.S. Department of Justice. Brazilian authorities had arrested him back on October 31, 2019, in São Paulo. It took roughly six years and eight months of negotiation between Brazilian and U.S. officials to get him on a plane to face charges here.

Prosecutors say Al-Mamun ran the operation with two other Bangladeshi nationals, Mohamad Milon Hossain, 46, and Moktar Hossain, 38. According to the DOJ, the three men spent years smuggling illegal aliens into the U.S. by staging them through São Paulo, Brazil, and moving them north through South America, Central America, and Mexico.

The Daily Star, a Bangladeshi outlet, reported additional detail on how the operation worked. Al-Mamun allegedly housed migrants in São Paulo and coordinated their onward journey. Milon allegedly sheltered them in Tapachula, Mexico, before moving them to Monterrey, where Moktar allegedly gave them instructions on how to cross the Rio Grande into Texas.

Migrants reportedly paid up to $10,000 each for the trip, according to the DOJ. The Daily Star cited a figure of up to 3.5 million taka, the Bangladeshi currency, which converts to roughly the same range.

Al-Mamun is charged with conspiracy to bring an alien to the United States, multiple counts of bringing an alien to the United States for financial gain, and conspiracy to encourage and induce illegal entry, according to the DOJ. If he's convicted on all counts, he faces up to 15 years in prison.

His two alleged co-conspirators already went through the system. Milon and Moktar were arrested in Mexico, and investigators say statements from detained Bangladeshi asylum seekers, plus intelligence gathered from the two men, helped authorities track down and arrest Al-Mamun in Brazil. Both Milon and Moktar pleaded guilty in the U.S. in 2021 and were sentenced to 46 months each in prison, according to both the DOJ and The Daily Star.

Homeland Security Investigations' Phoenix office led the case, with help from HSI Laredo, HSI's Washington and international offices in Brazil and Colombia, Customs and Border Protection, the U.S. Marshals Service, and unnamed international law enforcement partners, per the DOJ statement.

This isn't some isolated smuggler working a border crossing. It's a multinational logistics operation moving people from Bangladesh, on the other side of the planet, through half a dozen countries and into Texas. That takes money, coordination, and staging points that stayed operational for years before law enforcement caught up.

It also shows how slow international justice can move even when everyone agrees on the outcome. Al-Mamun was arrested in 2019. He wasn't sent to the U.S. until July 8, 2026. Brazil and the U.S. have an extradition treaty, but that process still took nearly seven years to play out, and neither the DOJ nor Brazilian authorities have publicly detailed exactly what caused the delay. Extradition fights over evidence, appeals in Brazilian courts, and diplomatic back-and-forth are common in these cases, but the specific holdup here hasn't been spelled out in the available records.

A reasonable defense argument, and one Al-Mamun's attorneys will presumably make in court, is that he hasn't been convicted of anything yet. These are allegations laid out by federal prosecutors, not a proven verdict. His co-defendants took plea deals, which resolved their cases but doesn't establish guilt for Al-Mamun specifically. He's entitled to contest the charges, and the 15-year maximum is a ceiling, not a guarantee.

The pattern from the two guilty pleas is instructive. Milon and Moktar admitted their roles and got sentences well below the statutory max, a common outcome when defendants cooperate or accept responsibility early. Whether Al-Mamun follows the same path or fights the charges at trial is now the open question in this case.

No trial date has been publicly announced yet. Al-Mamun remains in federal custody in Texas as the case proceeds.
