This business aviation blog post is part of a series on pre-clearing U.S. Customs in Ireland and continues from our last article: "Shannon U.S. Customs Pre-Clearance: Part 3 – Pre-Clearance Process."

After pre-clearing Customs and Border Protection (CBP) at Shannon (EINN), business aircraft operators may proceed directly to the U.S. However, you face certain limitations in terms of destination airports and post-landing procedures. It’s best to talk with your 3rd-party provider or EINN ground handler to ensure you’re aware of all requirements and procedures.

The following is an overview of what you need to know:

1. Airports you may operate to

After you clear at EINN, there are approximately 200 airports in the U.S. to which you may operate. This list of available airports has grown over the years and continues to grow. It’s a strict requirement that you land at an Airport of Entry (AOE) with a U.S. Department of Agriculture representative who’ll remove international waste. Once your EINN pre-clearance has been completed, confirmation of a successful pre-clearance is sent to the captain and your EINN ground handler. A U.S. Department of Agriculture representative, at the scheduled point of arrival stateside, will be notified by CBP to meet your aircraft.

2. You may not change airport of arrival in the U.S.

Once you’ve pre-cleared at EINN, you must operate to your specified/approved airport of entry in the U.S. If for any reason, including operational weather diversions, you elect to land at a different airport, your EINN pre-clearance is no longer valid, and you’ll need to re-clear CBP at an AOE on first landing in the U.S.

3. Additional information for travel through Ireland

More and more U.S. airports are accepting operations inbound from CBP pre-clearance at EINN. It’s important to remember that you must continue to one of the approved U.S. mainland airports after the EINN U.S. pre-clearance has been completed as alternatively CBP clearance will need to be repeated at an AOE.
