Bomber's citizenship application delayed?

Daily Mail:

The Department of Homeland Security was dragging its feet on processing Boston bombing suspect Tamerlan Tsarnaev's U.S. citizenship after a routine background check revealed he had been questioned by the FBI in 2011.

Tamerlan, 26, filed an application for citizenship six months ago but immigration officials had not yet made a decision on his case at the time of the Boston Marathon bombings.

Authorities knew the alleged bomber had a domestic violence charge on his record but the fact he had been grilled by federal agents is reportedly what threw up red flags, halting the progress of his application.

It's not clear what the 26-year-old, who was killed early Friday, was told about why his application was facing delays.

Official reported on Friday that the F.B.I. interviewed the older Tsarnaev brother in January 2011 at the request of the Russian government, which suspected that he had ties to Chechen terrorists.

They said this decision to delay his application proved his encounter with the F.B.I. did not go unnoticed by the Department of Homeland security.

According to The New York Times, the terror suspect's application, presented on September 5, also prompted the FBI to do 'additional investigation' of him this year. They didn't reveal how far the probe had gone or what it covered.

Tamerlan's papers were submitted just days after his brother, Dzhokhar A. Tsarnaev, 19, had his own citizenship application approved.

According to the Times, officials with Homeland Security contacted the FBI late last year to learn more about its interview with the terror suspect and the agency reported its conclusion that he did not present a threat.


However, immigration officials did not move to approve or deny the application, choosing instead to leave it open for 'additional review.'

If they did additional examination after September 5, why didn't they do an internet search so they could see his admiration for terrorist videos?   This seems like a lapse in investigatory skills.  It should have been enough to put him on a watch list and notify local law enforcement of the threat in their area.
