Congressional Budget Office Cost Estimate: H.R. 3488: Preclearance Authorization Act of 2014 [open pdf - 18KB]
"H.R. 3488 would authorize Customs and Border Protection (CBP) in the Department of Homeland Security to establish preclearance (inspection) stations in foreign countries. CBP currently operates preclearance facilities in about a dozen locations, mostly in Canada. The bill would require the agency to notify the Congress before establishing preclearance stations in countries that currently have none. H.R. 3488 also would specify policies and requirements to ensure that aviation security screening performed at foreign airports engaged in preclearance operations meet U.S. standards. CBP anticipates opening new preclearance stations over the next several years and can do so under current law, so we estimate that implementing the bill would not significantly affect agency spending. CBO [Congressional Budget Office] also expects that implementing the bill's requirements related to aviation security would not significantly affect federal costs. Enacting the legislation would not affect direct spending or revenues; therefore, pay-as-you-go procedures do not apply."
