What is required for travelers under the Guam-CNMI Visa Waiver Program?

Travelers under the Guam-CNMI Visa Waiver Program are required to have a round trip ticket with a confirmed departure date. This requirement is crucial because it helps ensure that travelers have a planned exit from Guam or the Commonwealth of the Northern Mariana Islands, thereby reducing the risk of overstaying their permitted entry or becoming undocumented. The round trip ticket serves as proof that the traveler intends to leave at the end of their visit, which is a key condition in many visa waiver programs to facilitate controlled and orderly travel.

In this context, other requirements like a passport validity and health certifications may vary by individual circumstances but do not specifically speak to the regulatory framework of the Visa Waiver Program concerning guaranteed travel plans. A letter of invitation is also not typically mandated for participation in this specific waiver program. Thus, the round trip ticket is the most critical item required for travelers under this program.
