Global Entry provides expedited U.S. customs and immigration clearance when you return from international travel. It also includes TSA PreCheck, which means faster security screening at U.S. airports on your way out.
If you travel internationally more than once a year, it’s worth the investment. The application involves a background check and an in-person interview, so plan ahead. Approval can take several weeks to a few months depending on demand.
If you already have Global Entry, make sure your Known Traveler Number (KTN) is linked to your airline reservations so your PreCheck status appears on your boarding pass.
