Terrorism is a hazard to human life and material prosperity that should be addressed in a sensible manner whereby the benefits of actions to contain it outweigh the costs. Foreign-born terrorists who entered the country, either as immigrants or tourists, were responsible for 88 percent (or 3,024) of the 3,432 murders caused by terrorists on U.S. soil from 1975 through the end of 2015. This paper presents the first terrorism risk analysis of the visa categories those foreign-born terrorists used to enter the United States.
