United States Customs and Border Protection
The United States Customs and Border Protection (USCBP) facility at Terminal 2 in Dublin Airport is a purpose built facility that allows US bound passengers to undertake all immigration, customs and agriculture inspections at Dublin prior to departure.
Having cleared USCBP, passengers arriving in the US are treated as domestic arrivals, which allows for a faster processing through their arrival airport in the United States including the checking through of any baggage to the traveller’s final destination.
Dublin Airport is one of only a handful of airports outside North America that offer the CBP facility.
