Preclearance exists at most major Canadian airports, which theoretically allow for more comfortable travel from these cities to the United States. Wait times at some busy pre-clearance facilities, particularly at Toronto Pearson Airport , may exceed wait times for the processing of passengers on unauthorized flights to destination airports and cause significant delays in departure plans. With the notable exceptions of LaGuardia Airport and Ronald Reagan Washington National Airport, many U.S. airports now have more customs facilities than when the early flight program was created in 1952. Airport authorities have experienced these delays in the downsizing of U.S. Customs and Border Guards, but arguments for increased personnel have been delayed due to national priorities. Nexus and other similar programs are now being explored and expanded to try to restore some of the original comfort for the preclearance process. The agreement is fully reciprocal in all modes of transportation, so that Canadian pre-ecclesial officers in the United States and the United States can perform CBP Preclearance officers to make a pre-report in Canada. The authorities granted in the agreement also apply to Canadian pre-cross officers working in the United States and U.S. pre-army pre-army officers in Canada.

border clearing system at its main airport and, according to Foreign Ministry spokesman Andrew Lee, the relevant departments are examining the issue and discussing how such a system could be implemented at Taiwan`s Taoyuan International Airport.  The New Preclearance Act always stipulates that any traveller travelling to the United States will be able to withdraw from the pre-declaration (unless it is retained in accordance with the law) and will leave the vestibule or perimeter.
