United States border preclearance facilities are prescreening border controls operated by the United States Department of Homeland Security at airports and other ports of departure located outside the United States under agreement between the host country and the federal government of the United States. Travelers are subject to immigration and customs inspections by U.S. Customs and Border Protection (CBP) officers before boarding their transportation onward to the United States. Preclearance applies to all passengers regardless of their nationality or purpose of travel. Upon arrival, precleared passengers are treated as domestic passengers and do not need to be screened again. This process is intended to streamline border procedures, reduce congestion at American ports of entry, and facilitate travel into airports that otherwise lack customs processing facilities. Its practice is questioned by civil liberty rights groups[by whom?][citation needed] (e.g., it could be used to prevent asylum seekers).

Preclearance facilities were first introduced in Toronto under an informal arrangement with the Canadian government, and are now available at eight major Canadian airports with facilities under consideration at sea ports and rail stations. Arrangements also exist with some airports in Bermuda, The Bahamas, Aruba, Ireland, and the United Arab Emirates.[1] Passengers traveling from a preclearance port arrive in the United States as domestic travelers, but are still subject to reinspection at the discretion of Customs and Border Protection.

Reasons for implementation[edit]

The preclearance program was introduced as an informal arrangement between Canada and the United States in 1952 at the request of American Airlines. The program aims to streamline border procedures for flights entering the United States, reduce congestion at ports of entry, and to facilitate travel into U.S. airports that may not be equipped to otherwise handle international travelers. Although more U.S. airports have expanded or introduced customs facilities since the preclearance program began, LaGuardia Airport and Ronald Reagan Washington National Airport remain the two largest U.S. airports without customs facilities for processing commercial flights.

Preclearance programs have been accused of being motivated by a desire to prevent the arrival of asylum seekers, who are otherwise protected under the 1951 Refugee Convention's provisions on non-refoulement once they arrive at their destination.[2]

Benefits and drawbacks[edit]

Preclearance is particularly beneficial to those who have an ongoing connection (such as a connecting flight) upon arrival in the United States, as there is no risk of border delays causing them to miss such a connection. A corresponding drawback, however, is that a delay in preclearance could cause the passenger to miss the outbound flight.

Precleared air travelers with further connections enjoy the convenience of having their baggage checked through to their next destination. Like connecting domestic passengers, they disembark into the sterile area of the airport and may walk directly to their next gate. Connecting international passengers who have not been precleared must collect checked baggage prior to customs inspection, walk their baggage through customs inspection, recheck their baggage for connecting flights, pass through security screening to enter the sterile area of the airport (because certain items allowed in checked baggage cannot be brought into the sterile area), and then proceed to their onward gates.

Another advantage is that CBP officers are able to ultimately exclude inadmissible passengers and prohibited goods before a flight, train journey, or voyage commences. This saves CBP the difficulty of dealing with them on U.S. soil and helps to minimize the risk of untoward incidents happening there. When a person is denied entry into the United States at a preclearance facility, he or she is not allowed to board the U.S.-bound flight and only has to leave the airport by land transport instead of being put on a return flight (unless the passenger arrived at the preclearance airport from an earlier flight).

Preclearance also provides considerable flexibility to the airlines operating in those routes where such a program is available. For example, major U.S. airlines and their subsidiaries routinely operate many daily flights from locations like Toronto or Nassau to New York City. The presence of preclearance facilities in Toronto and Nassau enables airlines to conveniently direct their flights from those airports to land at LaGuardia Airport (which has no border protection facilities) instead of John F. Kennedy International Airport (JFK) or Newark Liberty International Airport (EWR), thereby allowing them to save valuable landing slots at JFK and EWR for other international arrivals from overseas airports which lack CBP preclearance facilities.

Preclearance exists at most major Canadian airports, theoretically enabling more convenient travel from those cities to the United States. The waits at some busy preclearance facilities, notably Toronto Pearson Airport (the busiest U.S. preclearance facility),[3] can often exceed the waiting times for processing passengers from non-precleared flights at destination airports and cause significant delays to departure schedules. With the notable exceptions of LaGuardia Airport and Ronald Reagan Washington National Airport, many U.S. airports now have more customs facilities compared to when the preclearance program first started in 1952. Airport authorities have blamed these delays on reduced staffing levels by U.S. Customs and Border Protection, but pleas for increased staffing have been answered with deferrals due to domestic priorities. NEXUS and similar programs are now being explored and expanded as a means to try to restore some of the original convenience to the preclearance process.

CBP also sets the hours of operation of its preclearance facilities, which often tend to be shorter than the operating hours of the airports, seaports, or railway stations they operate in. Transportation operators who would like their passengers to be able to take advantage of such a facility will need to schedule their departure times to coincide with the preclearance facilities' operating hours. Carriers may launch flights from preclearance airports to the U.S. outside CBP preclearance operating hours, but passengers who choose to take such flights will be processed in the same way as most other international passengers upon arrival on American soil.

Legal restrictions[edit]

Preclearance facilities exist because of agreements made between the U.S. federal government and the governments of the host countries. Travelers who have passed through preclearance facilities, but whose flight or ship has not departed, remain in the legal jurisdiction of the host country. U.S. officials may question and search travelers with such passengers' permission. They lack the power to make arrests (for customs or immigration violations or for the execution of outstanding warrants), but can deny boarding.[citation needed]

Some countries have laws in place that specifically cover preclearance issues. Since CBP does not have legal powers on foreign soil, passengers can be arrested and detained for offences in the host country only by local authorities. Therefore, if a CBP officer has any security but non-immigration/customs-related concerns about a traveller, the attending CBP officer will need to refer the matter to local officials. Passengers can choose to abandon their flight and refuse search, and unlike in the United States, officers cannot search them without permission. Most preclearance facilities have a sign explaining so. CBP Officers in the Preclearance Division are not armed on foreign soil.[4][5] However, it is likely that if the Canadian Parliament approves Bill C-23, CBP officers would be allowed to carry sidearms on duty in Canada if they are working in an environment in which Canada Border Services Agency officers are normally armed.[6]

Informal preclearance arrangements between the United States and Canada began at Malton Airport (now Toronto Pearson International Airport) in 1952, following a request from American Airlines. This was extended and formalized with Canada's passage of the Air Transport Preclearance Act in 1974, the 1999 Preclearance Act,[7] and with the 2001 Canada–U.S. Agreement on Air Transport Preclearance.[8] The preclearance agreement is fully reciprocal, meaning the government of Canada has the option of opening Canadian Preclearance facilities in the United States. On average, however, U.S. international airports offer far fewer flights to Canada compared to the reverse, making this an expensive and inefficient proposition that, as of 2019, has not been exercised by the Canadian government.

On March 16, 2015, U.S. and Canadian officials signed the ministerial-level Agreement on Land, Rail, Marine, and Air Transport Preclearance Between the Government of the United States of America and the Government of Canada, which foresees significant expansion of the scope of preclearance facilities. For instance, under the new agreement, U.S. CBP officers working at U.S. preclearance facilities in Canada will be able to carry firearms and detain travelers who try to voluntarily withdraw their outbound travel or willingly leave the preclearance area. Although CBP does not have arrest powers in Canada, the bill also includes increased cooperation with the Canada Border Services Agency to arrest travelers found to be breaking the law.[9]

On March 10, 2016, U.S. and Canadian officials announced that preclearance would become available at Billy Bishop Toronto City Airport, Québec City Jean Lesage International Airport, and Montreal Central Station. The necessary upgrades in Quebec City was anticipated to take 18 months and $35 million CAD to complete.[10]

On December 8, 2016, U.S. President Barack Obama signed the bipartisan Promoting Travel, Commerce and National Security Act of 2016 into law, enabling an expansion of US-Canada preclearance.[11] On December 12, 2017, Canadian Governor General Julie Payette gave royal assent to the Canadian counterpart legislation: the Preclearance Act, 2016.[12] The main obstacles to implementing this expanded preclearance regime are orders-in-council in Canada, a joint agreement between President Donald Trump and Prime Minister Justin Trudeau, and an official presidential proclamation from Trump.[citation needed] In Canada, the preclearance measures interface with the Quarantine Act in the case of a public health emergency.


The following Canadian airports operate U.S. preclearance facilities:[13]

At the request of Porter Airlines, a new terminal building at Billy Bishop Toronto City Airport (Toronto island) officially opened in Fall 2010 and includes both Canada Border Services Agency customs facilities and provisions for U.S. Customs and Border Protection preclearance facilities. The latter was, however, denied by Washington at the time.[14][15] On March 10, 2016, American and Canadian officials announced that preclearance would become available at Billy Bishop Toronto City Airport and Québec City Jean Lesage International Airport. The necessary upgrades in Quebec City were anticipated to take 18 months and $35 million CAD to complete.[10]

The traditional airport security inspection in the U.S. departure area is before the separate Preclearance area. It was processed by Canadian Air Transport Security Authority (CATSA) to meet the standards of both Canada and U.S. TSA regulations.[16]


There are currently no full United States preclearance facilities for rail passengers in Canada. A partial customs inspection is conducted by CBP and Canada Border Services Agency officers at Pacific Central Station in Vancouver, British Columbia for passengers departing on the Amtrak Cascades rail service to Seattle, Washington and Portland, Oregon.[17] Despite not making any other stops within Canada, U.S.-bound Cascades trains are still subject to a full inspection by CBP at the United States border in Blaine, Washington.[17]

In May 2012, U.S. Senators Chuck Schumer (D-NY), Kirsten Gillibrand (D-NY), Patrick Leahy (D-VT), and Bernie Sanders (I-VT) sent a letter to President Barack Obama urging him to fast track the approval of a preclearance facility at Montreal Central Station, which would allow U.S.-bound travelers on Amtrak's Adirondack to bypass an existing immigration stop at Rouses Point, New York for entering the United States.[18] On March 16, 2015, the United States and Canada signed an agreement that would allow for such a facility.[19][9] Schumer has also promoted the opening of a Canadian preclearance facility in the United States for passengers of the Amtrak-Via Maple Leaf train service between Toronto and New York City; during a visit to the Niagara Falls Amtrak station in January 2020, he called on the Canadian government to accelerate a previously-announced 2019 plan to implement a Canadian preclearance facility at the station.[20]


The United States operates several immigration-only pre-inspection posts (traditional, full customs processing is still performed upon arrival in the United States) at the port of Victoria for both the Black Ball Line MV Coho car ferry service to Port Angeles, Washington and the Victoria Clipper passenger-only ferry to Seattle, Washington; and the same program operates at the terminal in Sidney for Washington State Ferries' Anacortes–San Juan Islands ferry service to Anacortes, Washington.[citation needed]

Another U.S. preclearance post is also located at the Port of Vancouver. This post is particularly valuable to travelers on cruise liners that visit Alaska or that depart from Vancouver and have a first stop at U.S. cities situated along the west coast of North America.[citation needed]

Caribbean and Atlantic Ocean[edit]

Informal preclearance with Bermuda began in 1960. The Bahamas and the United States signed a treaty in June 1974 formalizing the process.[citation needed]

Plans were underway for a preclearance facility to be opened at Punta Cana International Airport, located in the popular tourist destination of Punta Cana, Dominican Republic, to be operating by the end of summer 2009.[21] Further plans were made in April 2016 to open a facility the next year;[22][23] but as of March 2018, the facility had not yet opened. In April 2011, a team from the U.S. Department of Homeland Security traveled to Jamaica for talks with Jamaican government and tourism officials on opening future preclearance facilities on the island.[24]


U.S. Customs and Border Protection at Shannon

The United States and Ireland entered into a preinspection arrangement in 1986.[25] Shannon Airport initially offered only immigration checks, while customs and agriculture inspections were still done upon arrival in the United States. This procedure is more properly known as preinspection (not preclearance). In August 2009, Shannon opened an addition to its preclearance facility that provided these previously-lacking customs and agriculture inspections. The facilities at Dublin Airport, like those at Shannon, also initially offered only immigration checks on select flights. In January 2011, a section of the then-recently opened Terminal 2 was opened with dedicated preclearance with full CBP facilities.[26] Both airports now allow U.S.-bound commercial flights that use the preclearance facilities to arrive at domestic terminals instead of international terminals, which in turn allows arriving passengers to leave U.S. airports upon landing without further inspection. Since March 2010, the Shannon preclearance facility is also available for use by private aircraft. However, the Dublin facility is only available for commercial flights.

In 2017, U.S. Executive Order 13769 implemented a ban on passport-holders of seven countries, preventing traveling to the United States. In response, the Irish government announced that there would be a "complete review" of preclearance arrangements.[27]

United Arab Emirates[edit]

In December 2011, the government of Abu Dhabi signed a letter of intent to construct a terminal that, when opened, would house a U.S. border preclearance facility.[28]

On June 6, 2013, the U.S. House passed an amendment offered by Representatives Pat Meehan (R-PA), Candice Miller (R-MI) and Peter DeFazio (D-OR), which prohibits the U.S. Department of Homeland Security (DHS) from using any taxpayer dollars to conduct Customs and Border Protection (CBP) preclearance operations at Abu Dhabi International Airport (AUH). The amendment was unanimously adopted during floor consideration of the FY14 Homeland Security Appropriations bill.[29] On November 14, 2013, Rep. Patrick Meehan (R, PA-7) introduced the Preclearance Authorization Act of 2014 (H.R. 3488; 113th Congress), which would authorize the United States Secretary of Homeland Security (DHS) to establish preclearance facilities, conduct preclearance operations, or provide customs services outside of the United States to prevent terrorists, terrorist instruments, and other national security threats from gaining access to the United States.[30] Meehan indicated that the goal of the bill would be to prevent CBP from opening a preclearance facility at Abu Dhabi International Airport in the United Arab Emirates. Currently, just one airline flies from Abu Dhabi to the United States: Etihad, a state-run airline.[31] Supporters of the bill wished to avoid giving Etihad an unfair competitive advantage created by the fact that travelers flying through Abu Dhabi (on Etihad) would be able to use preclearance, while passengers on other airlines would not.[31] This bill did not pass into law.

The U.S. customs preclearance facility at Abu Dhabi International Airport officially opened on January 26, 2014.[32] Another U.S. customs preclearance facility is currently being planned for Dubai International Airport.[33]

Future plans[edit]

On March 16, 2015, the United States and Canada signed an agreement to construct a preclearance facility at Montreal Central Station. The facility would eliminate a border stop for Amtrak's Adirondack service and would support a future extension of the Vermonter to Montreal.[19][9]

In May 2015, the United States Department of Homeland Security announced that the following airports will be considered for the expansion of the border preclearance scheme:[34]

  1. Brussels Airport, Belgium
  2. Punta Cana Airport, Dominican Republic
  3. Narita International Airport, Japan
  4. Amsterdam Airport Schiphol, Netherlands
  5. Oslo Airport, Norway
  6. Madrid-Barajas Airport, Spain
  7. Stockholm Arlanda Airport, Sweden
  8. Istanbul Atatürk Airport, Turkey
  9. London Heathrow Airport, United Kingdom
  10. Manchester Airport, United Kingdom.

On November 4, 2016, Sweden and the United States signed an agreement that would make Sweden the second European country, after Ireland, to offer preclearance, although no announcement has been made as to when the service will start. On that same date, DHS also announced that eleven more airports in nine countries had been added to the list of possible preclearance airports:[35]

  1. El Dorado International Airport (BOG) in Bogota, Colombia
  2. Ministro Pistarini International Airport (EZE) in Buenos Aires, Argentina
  3. Edinburgh Airport (EDI) in Edinburgh, United Kingdom
  4. Keflavik International Airport (KEF) in Iceland
  5. Mexico City International Airport (MEX) in Mexico City, Mexico
  6. Milan-Malpensa Airport (MXP) in Milan, Italy
  7. Kansai International Airport (KIX) in Osaka, Japan
  8. Rio de Janeiro-Galeão International Airport (GIG) in Rio de Janeiro, Brazil
  9. Leonardo da Vinci-Fiumicino Airport (FCO) in Rome, Italy
  10. São Paulo-Guarulhos International Airport (GRU) in São Paulo, Brazil
  11. Princess Juliana International Airport (SXM) in St. Maarten.

On 23 March 2018, the Taiwanese newspaper Liberty Times reported that the U.S. had conditionally agreed to the establishment of a border preclearance system in Taiwan. The Taiwanese government is assessing the possibility of establishing a United States border preclearance system at its main airport, and according to Ministry of Foreign Affairs (MOFA) spokesman Andrew Lee, the relevant government ministries are examining the issue and discussing how such a system could be put in place at Taiwan Taoyuan International Airport.[36]

On 18 August 2019, outgoing U.S. Ambassador to Colombia Kevin Whitaker stated that U.S. preclearance at El Dorado International Airport would be available within the next year, according to an interview with El Tiempo.[37][38][39]

Aborted plans[edit]

Ministry of Foreign Affairs of South Korea stated that the government of South Korea plans to establish the U.S. preclearance system at Incheon International Airport. On January 15, 2015, however, Incheon International Airport announced that it would not introduce the U.S. preclearance. Instead, an in-depth analysis concluded that U.S. preclearance could lead to decreased sales at duty-free shops, despite the potential income from usage fees remitted for the use of preclearance space.[40]

On May 23, 2015, an unofficial member of the Executive Council of Hong Kong, Regina Ip, revealed in an interview that the United States and Hong Kong had explored the possibilities "some 20 or 30 years ago" to set up the preclearance arrangements at Kai Tak Airport. According to Ip, she was dispatched by the Secretary for Security, in her capacity as a career civil servant in the Security Branch, to study the arrangements in Canada, but the plan was subsequently shelved because of room constraints at Kai Tak.[41][42][43][44]

On February 1, 2017, the Netherlands pulled out of talks with the United States to set up a preclearance program at Amsterdam Airport Schiphol because of U.S. President Donald Trump's Executive Order 13769, which banned travel to the United States by citizens of certain Muslim-majority countries.[45] On 22 June 2018, the Dutch Government made it known that they were resuming plans for a pre-clearance facility at Amsterdam Airport Schiphol.[46]
