Twenty seven-year-old Akayed Ullah, who attempted to suicide bomb (I say attempted because he survived after injuring himself and four other people) the New York City subway system during rush hour Monday morning, was an immigrant from Bangladesh. He came to the United States in 2011 through family chain migration.

“DHS can confirm that the suspect was admitted to the United States after presenting a passport displaying an F43 family immigrant visa in 2011. The suspect is a Lawful Permanent Resident from Bangladesh who benefited from extended family chain migration," Homeland Security Press Secretary Tyler Houlton confirmed.

During the daily briefing Monday afternoon, White House Press Secretary Sarah Sanders reiterated President Trump's plans to end chain migration into the United States.

"The president’s policy has called for an end to chain migration, and if that had been in place that would have prevented this individual from coming to the United States. So the president is aggressively gonna continue to push forth responsible immigration reform, and ending chain migration would certainly be a part of that process,” Sanders said. "We know that the president’s policy calls for an end to chain migration, which is what this individual came to the United States through, and if his policy had been in place, then that attacker would not have been allowed to come in the country.”

President Trump has repeatedly called for the end to chain migration. He did so again last month after an Islamic terrorist from Uzbekistan drove a truck into pedestrians and bicyclists in New York City, killing nearly a dozen people.
