Under preclearance, where does processing by U.S. customs and immigration occur?

• A. On arrival in the US
• B. In a foreign city
• C. It never involves the US border
• D. At the national airport hub only

Answer: (B)

Preclearance moves U.S. customs and immigration processing to a foreign city before you depart. Because you complete the border checks there, you arrive in the United States already cleared, treated as a domestic traveler, and there’s no additional U.S. border processing when you land. This isn’t limited to one national hub and isn’t done after arrival in the U.S.; it happens at selected foreign airports or facilities before boarding. For example, you might clear U.S. immigration in Dublin or Toronto before flying to the U.S., so you’re free to exit to baggage claim or your next connection as a domestic arrival.
