US SB842

Requires the Secretary of State to assess within 180 days whether any Latin American country, region, or jurisdiction qualifies as a "terrorist sanctuary" under existing law, based on Hezbollah or other terrorist organization activity

Authorizes the President to impose visa sanctions on government officials from jurisdictions designated as terrorist sanctuaries, including visa revocation and inadmissibility to the United States

Expresses congressional sense that the State Department should pressure Latin American governments to designate Hezbollah as a terrorist organization, using Argentina's model as a blueprint, and work through forums like the Financial Action Task Force to greylist cooperating entities

Only five Latin American countries currently designate Hezbollah as a terrorist organization: Argentina, Colombia, Guatemala, Honduras, and Paraguay

Sanctions include presidential waiver authority for national security reasons and terminate automatically 5 years after enactment
