US Border Information

The US Customs and Border Protection (CBP) agency has a presence in six countries, with 600 personnel working at overseas airports.
You'll find US preclearance facilities at Dublin Airport (DUB) and Shannon Airport (SNN) in Ireland.
In 2019, the CBP processed over 22 million passengers across all Preclearance locations worldwide, which is about 16% of all commercial air travelers headed for the US.
Why Open Two CBP Facilities in Ireland?
Opening two Customs and Border Protection (CBP) facilities in Ireland was a strategic move to cater to the large number of Americans visiting the Emerald Isle each year.
More than 31.5 million Americans claim to be of Irish descent today, thanks to a massive emigration that peaked between 1845 and 1852 during the Great Famine.
This significant Irish-American population has led to a substantial increase in tourism between the two countries.
Over 2 million people emigrated from Ireland to the United States during this time, a quarter of the entire population.
The CBP facilities in Dublin and Shannon were likely established to provide efficient and secure processing for these travelers.
US Border
