WASHINGTON (AP) - Senators weighing amendments to a sweeping immigration bill have agreed to boost security provisions around student visas.
Lawmakers said they were taking the step in response to the Boston Marathon bombings.
A foreign student accused of hiding evidence for one of the alleged bombers was allowed to return to the U.S. in January without a valid student visa.
The amendment by Republican Sen. Chuck Grassley of Iowa would require the homeland secretary to ensure that border patrol agents at U.S. ports of entry would have access to information on the status of student visas.
The Senate Judiciary Committee agreed to the amendment by voice vote Tuesday.
