Do I have to go through customs for a connecting flight in San Francisco?

Navigating Customs at San Francisco International Airport for Connecting Flights

When connecting through San Francisco International Airport (SFO) on an international flight, it’s crucial to understand the customs procedures for a seamless and timely transfer.

Customs Requirement:

Generally, passengers arriving on international flights at SFO will need to pass through U.S. Customs and Border Protection (CBP), which includes a mandatory federal inspection. This applies to connecting flights as well, unless specifically exempted by a pre-clearance program.

Pre-Clearance Programs:

For certain international destinations, SFO offers pre-clearance programs that allow passengers to complete U.S. Customs and Border Protection inspections before their departure. This can significantly expedite the customs process in San Francisco for connecting flights. Current pre-clearance locations from which passengers can connect include Dublin, Ireland; Vancouver, Canada; Calgary, Canada; and Toronto, Canada.

Sufficient Time Allocation:

Passengers should allow ample time for the mandatory customs inspection. The exact processing time can vary based on factors such as flight volume, the number of passengers, and any additional screenings required. It’s advisable to factor in at least an hour for customs clearance, especially during peak travel periods.

Process Outline:

Upon arriving at SFO from an international destination, passengers will typically:

1. Disembark the aircraft and proceed to the designated immigration area.
2. Present their passport and any other required documents to a CBP officer.
3. Undergo a brief interview and provide fingerprints (for most travelers).
4. Collect their checked baggage and proceed to the customs area.
5. Declare any goods or items subject to customs duties and present them for inspection.
6. Retrieve any remaining checked baggage and proceed to their connecting flight.

Tips for a Smooth Customs Experience:

• Arrive at SFO well in advance of your connecting flight to allow sufficient time for customs clearance.
• Ensure you have all necessary travel documents, including your passport, boarding pass, and any visas required.
• Be prepared to declare any goods or items you are bringing into the United States.
• Be aware of any restrictions or prohibitions on certain items.
• Follow the instructions of CBP officers and be cooperative during the inspection process.

By following these guidelines, passengers can navigate customs at San Francisco International Airport for connecting flights efficiently and avoid any unforeseen delays.
