Two men charged in connection with the Boston Marathon bombings on Wednesday were in the U.S. on student visas and classmates of the surviving suspect, Dzhokhar Tsarnaev, at the University of Massachusetts at Dartmouth, The New York Times reported . Dias Kadyrbayev and Azamat Tazhayakov, 19-year-old citizens of Kazakhstan, were charged with conspiring to obstruct justice and destroy evidence, specifically a computer and backpack containing fireworks, both belonging to Tsarnaev. A third suspect, Robel Phillipos, 19, of Cambridge, Mass. and a former UMass Dartmouth student, was charged with making false statements to authorities.
Kadyrbayev and Tazhayakov are also accused of violating their student visas. Kadyrbayev is no longer enrolled at UMass Dartmouth, while Tazhayakov, a current student, has been suspended in light of the charges.
Since the Boston Marathon bombings, there have been some signs of a backlash from the political right against the student visa system, despite the fact that, until Wednesday, there were no indications that international students were involved in the plot (the elder of the alleged perpetrators was a permanent resident and the younger a naturalized U.S. citizen). Most notably, Senator Rand Paul, a Republican from Kentucky, issued a letter  questioning whether student visas should be suspended, at least for students coming from “high-risk areas” of the world.
