This bill amends the Homeland Security Act of 2002 to require the Department of Homeland Security (DHS) to provide annual threat analyses and guidance to State, local, Tribal, and territorial governments. These analyses will specifically address potential terrorism threats posed by foreign nationals seeking to meet with government officials or access sensitive information, facilities, programs, or systems. The required threat analysis and guidance will include descriptions of high-risk government targets , an analysis of trends related to foreign national visits based on vetting requests, and recommended actions to mitigate homeland security threats. This aims to protect government officials, information, facilities, programs, and systems from potential risks. Furthermore, if DHS identifies a particular government entity or asset as a high-risk potential target , the Secretary must conduct outreach, provide classified or unclassified information, and offer assistance in vetting the foreign national. After such visits, DHS will request debriefings to maintain awareness of foreign national access attempts and techniques used. The bill also directs the Secretary of Homeland Security to coordinate research and development of technology to enhance information sharing for these purposes.
