U.S. Senator Rand Paul, a Republican from Kentucky, has posed the question of whether student visas should be suspended in light of the Boston Marathon bombing. Although neither of the suspected bombers was in the United States on student visas (one was a permanent resident, and the other a naturalized citizen), Paul nonetheless raises the student visa system as an area of concern in a letter about national security and the immigration system, asking: “Finally, do we need to take a hard look at student visas? Should we suspend student visas, or at least those from high-risk areas, pending an investigation into the national security implications of this program?”
Paul raises the issue of potential flaws in the student visa system, as well as in the system for admitting refugees, as part of his broader point that the Senate should not proceed in enacting comprehensive immigration reform "until we understand the specific failures of our immigration system. Why did the current system allow two individuals to immigrate to the United States from the Chechen Republic in Russia, an area known as a hotbed of Islamic extremism, who then committed acts of terrorism?"
