When it comes to the Visa Waiver program, clients often ask me, what happens when a Visa Waiver traveler who is in the U.S. visits a third, non-adjacent country, and then seeks to return to the U.S.? Do they receive a new 90-day period upon re-entering the United States? What if they go to Mexico or Canada or another adjacent country?
According to the CBP, An alien admitted into the United States under the Visa Waiver Program (VWP) who departs to visit a third country other than contiguous territory or an adjacent island and then returns to the United States to apply for admission as a temporary visitor for business or pleasure under the VWP, would receive a new 90-period of admission if he is found to be admissible.
If the same alien traveled only to foreign contiguous territory or an adjacent island, he would generally be readmitted for the balance of his original period of admission if found to be admissible. An alien is this situation may request to be admitted for a new 90-day period and be admitted for that new period if slbe is found to be admissible.
Please note that any VWP applicant for admission must establish his admissibility to the satisfaction of the inspecting CBP officers. An alien seeking a new 90-day period of admission under the VWP after departing the United States to “visit” a third country should expect to undergo greater scrutiny than most other VWP applicants. So this is possible but expect a tough time trying to get back in.
