Tazhayakov was a friend and classmate of Dzhokhar Tsarnaev's at the University of Massachusetts Dartmouth. Tazhayakov left the U.S. in December and returned Jan. 20. But in early January, his student-visa status was terminated because he was academically dismissed from the university.
Tazhayakov and a second Kazakh student were arrested this week on federal charges of obstruction of justice. They were accused of helping to get rid of a backpack containing fireworks linked to Tsarnaev. A third student was also arrested and accused of lying to authorities.
A spokesman for the department, Peter Boogaard, said earlier this week that the government was working to fix the problem, which allowed Tazhayakov to be admitted into the country when he returned to the U.S.
Under existing procedures, border agents could verify a student's status in SEVIS only when the person was referred to a second officer for additional inspection or questioning. Tazhayakov was not sent to a second officer when he arrived, because, Boogaard said, there was no information to indicate Tazhayakov was a national security threat. Under the new procedures, all border agents were expected to be able to access SEVIS by next week.
The government for years has recognized as a problem the inability of border agents at primary inspection stations to directly review student-visa information. The Homeland Security Department was working before the bombings to resolve the problem, but the new memo outlined interim procedures until the situation was corrected.
Under the new procedures, border agents will verify a student's visa status before the person arrives in the U.S. using information provided in flight manifests. If that information is unavailable, border agents will check the visa status manually with the agency's national targeting data center.
