Homegrown violent extremists are those who encourage, endorse, condone, justify, or support the commission of a violent criminal act to achieve political, ideological, religious, social, or economic goals by a citizen or long-term resident of a Western country who has rejected Western cultural values, beliefs, and norms.1 Homegrown violent extremists are a diverse group of individuals that can include U.S.-born citizens, naturalized citizens, green card holders or other longterm residents, foreign students, or illegal immigrants. Regardless of their citizenship status, these individuals intend to commit terrorist acts inside Western countries or against Western interests abroad.
