U.S. Customs and Border Protection no longer process waiver requests at Preclearance locations in Canada.
Travelers may continue to apply for a Waiver at the U.S. Embassy in Ottawa or at U.S. Consulates. In addition, CBP will continue to process Forms I-192, I-212 and I-824 at designated ports of entry. Waiver applicants are encouraged to submit their applications online via e-SAFE.
