H.R. 6323 would delay for up to 60 days any waiver by the Administration of sanctions against foreign financial institutions that knowingly facilitate transactions involving Iranian persons on the Department of Treasury’s Specially Designated Nationals and Blocked Persons list in order to allow for Congressional review. The waiver could not be issued during that waiting period unless a joint resolution of approval is enacted. Alternatively, the Congress could block the waiver by enacting a joint resolution of disapproval. If the Congress does not enact either resolution by the end of the waiting period, the Administration could waive the sanctions at that time.
