A bipartisan bill designed to improve cross-border travel between Canada and the U.S. has passed Congress and is headed to the president’s desk. The bill, officially known as the ?Promoting Travel, Commerce, and National Security Act? aims to streamline travel and commerce between the U.S. and Canada by allowing for more pre-clearance of passengers traveling between countries. Pre-clearance is when passengers undergo border inspections prior to traveling and can help to avoid bottlenecks at border-crossings.
