What action does the FBI take when a foreign group linked to terrorism abroad has members in the United States?

The approach taken by the FBI in counterterrorism investigations is based on the need both to prevent incidents where possible and to react effectively after incidents occur. Our investigations focus on the unlawful activity of the group, not the ideological orientation of its members. When conducting investigations, the FBI collects information that not only serves as the basis for prosecution, but also builds an intelligence base to help prevent terrorist acts.
