The US Customs and Border Protection (CBP) has designated 14 ports of entry where it plans to optimize the processing of Canadian TN NAFTA Professionals and L-1 Intracompany Transferees. The goal is to process these admissions more efficiently. Canadian TN and L-1 nonimmigrants are visa-exempt and can apply in either of these classifications directly at a Class A port of entry or at a Preclearance/Preflight facility. TN and L-1 nonimmigrants can continue to apply for admission at other qualifying ports of entry and are not limited to these designated ports. The designated ports for optimized processing are: Lester B. Pearson International Airport, Trudeau International Airport, Vancouver International Airport, Calgary International Airport, Highgate Springs Ports of Entry, Derby Line Port of Entry, Alexandria Bay Port of Entry, Peace Bridge Port of Entry, Rainbow Bridge Port of entry, Champlain Port of Entry, Detroit Canada Tunnel Port of Entry, Detroit Ambassador Bridge Port of Entry, Blaine Peace Arch Port of Entry, and Sweetgrass Port of Entry. The exact locations of each of these designated ports of entry and days and hours of operation can be found at: http://www.cbp.gov/travel/international-visitors/canada-mexico-travel/traveling-tn-or-l-1-visa-canada
