Can a VWP applicant for Admission Be Readmitted To the United States Follwing a Short Trip To an Adjacent Island, Canada, or Mexico?
Generally, VWP applicants admitted under the VWP may be readmitted to the United States after a departure to Canada or Mexico or adjacent islands for the balance of their original admission period. This is provided they are otherwise admissible and meet all the conditions of the VWP, with the exception of arrival on a signatory carrier, in which case the inspecting officers have the discretion to grant the applicants entirely new periods of admission.
