New York City terror suspect, 27-year-old Akayed Ullah, is the fourth Bangladeshi national in the United States to be accused of terrorism in a little more than a decade.

Ullah, as Breitbart News reports, allegedly planned to detonate a homemade bomb in New York City on Monday. Though the terror plot was botched, Ullah is accused of leaving at least three individuals injured. The Bangladeshi national originally entered the U.S. in 2011 with his parents and three-four siblings.

The terror suspect is the fourth Bangladeshi national to enter the U.S. as an immigrant, only then to plot to harm Americans:

In 2015, 24-year-old Bangladeshi national Rahatul Ashikim Khan was convicted and sentenced to ten years in federal prison for providing material support to terrorists with the al-Shabaab terrorist organization.

Between 2011 and 2012, Khan worked to coordinate overseas travel for an undercover Federal Bureau of Investigation (FBI) agent whom he believed was a violent jihadist. Khan even made arrangements to place the undercover agent into an Al-Shabaab pipeline that was run by Gufran Ahmed Kauser Mohammed and Mohamed Hussen Said.

Additionally, Khan led a group of Islamic terrorist-sympathizers in Austin, Texas, who pledged loyalty to then-Taliban leader Mullah Omar.

In 2013, 21-year-old Bangladeshi national Quazi Mohammad Rezwanul Ahsan Nafis was convicted and sentenced for planning what he thought was a 1,000-pound bomb at the New York Federal Reserve Bank in Lower Manhattan’s financial district. Such an attack would have killed hundreds and possibly thousands of Americans.

Nafis entered the U.S. on an F-1 visa — the program under which thousands of international students are allowed to come to the U.S. every year — with immediate intent to conduct a terrorist attack for the al-Qaeda terrorist organization.

After arriving in the U.S. in 2012, Nafis tried to recruit fellow Islamic extremists in New York to form a terrorist cell in the country that would regularly plot terrorist attacks against Americans. One of the individuals Nafis attempted to recruit was actually working as an undercover FBI source.

Between 2012 and 2013, Nafis planned the attack, seeking out several high-profile locations, including the New York Stock Exchange. The FBI ultimately thwarted the terrorist plan after the undercover agent supplied Nafis with a fake bomb and arrested him at the scene of the planned attack.

In 2006, Bangladeshi-born 49-year-old Mohammed M. Hossain was convicted and sentenced to 15 years in prison after helping an FBI informant with a plot to sell weapons to terrorists.

Hossain was the leader of a mosque in Albany when he was involved in a fictitious plot contrived by the FBI to aid foreign terrorists after the September 11, 2001, terrorist attacks in New York City.

As Breitbart News reported, mass immigration from Bangladesh has been spurred by a process known as “chain migration,” where new immigrants can bring an unlimited number of foreign relatives to the U.S. with them.

Since 2005, the U.S. has admitted and resettled 141,501 Bangladeshi nationals who entered because their foreign relatives were already living in the country. In 2016 alone, more than 18,000 Bangladeshi nationls entered the U.S. because their foreign relatives were living in the country:

About 9.3 million foreign nationals have come to the U.S. as chain migrants between 2005 and 2016, Breitbart News reported. In that same period, 13.06 million foreign nationals have entered the U.S. through the legal immigration system, as every seven out of ten new arrivals come to the country for nothing other than family reunification.

This makes chain migration the largest driver of immigration to the U.S. — making up more than 70 percent — with every two new arrivals bringing seven foreign relatives with them.
