Generally, this process works out well for passengers, who can schedule tighter connections without the risk of missing a flight because of immigration or security checkpoint delays. As you can imagine, stationing hundreds of immigration officers abroad is hardly a small expense, but the program does give inspectors an opportunity to live in another country (usually for a few months at a time).
Well, Secretary of Homeland Security Jeh Johnson today announced the intention to expand Preclearance to an additional 10 airports in nine countries, including Brussels Airport, Belgium; Punta Cana Airport, Dominican Republic; Narita International Airport, Japan; Amsterdam Airport Schiphol, Netherlands; Oslo Airport, Norway; Madrid-Barajas Airport, Spain; Stockholm Arlanda Airport, Sweden; Istanbul Ataturk Airport, Turkey; and London Heathrow Airport and Manchester Airport, United Kingdom.
In a statement, DHS said that nearly 20 million passengers traveled to the US from these 10 airports last year, so this does sound like a good move. It's unclear if Global Entry will be available, but (with a few exceptions) these facilities typically process passengers a bit more quickly than their counterparts in the US.
