A: Yes. If you are continuously referred to secondary inspection and believe the referrals may be caused by incorrect or mismatched information in government systems, DHS TRIP is the formal redress process for travel-screening problems. A successful TRIP inquiry does not guarantee you will never be sent to secondary again, because CBP can still refer you for other reasons.
