The Northern Mariana Islands (NMI), including Saipan, operate as an U.S. Commonwealth. This influences entry requirements for visitors. U.S. Citizens and Nationals do not strictly need a visa or passport. However, a valid government-issued photo ID (like a driver's license) and proof of U.S. Citizenship (like a birth certificate) are recommended for smooth air travel. A U.S. Passport serves as the most convenient form of identification.
U.S. Permanent Residents (Green Card Holders) present their valid green card and a passport from their country of nationality. Citizens of Visa Waiver Program (VWP) Countries (e.g., Australia, Japan, South Korea, most Western European countries) entering under the U.S. Visa Waiver Program for up to 90 days need an approved ESTA (Electronic System for Travel Authorization) prior to travel. A valid passport is also needed. Obtain your ESTA well before your trip. Citizens of Specific Countries under the CNMI Visa Waiver Program (e.g., China, Russia) may enter the CNMI for up to 45 days without a visa. They meet specific criteria, including holding a valid machine-readable passport, having a confirmed onward or return ticket, and completing an I-736 form. This program differs from the general U.S. VWP. Other Nationalities generally need a valid U.S. Visa (B-1 for business, B-2 for tourism, or combined B-1/B-2). VisaHQ helps with visa and passport services.
For international visitors, a passport valid for at least six months beyond your intended stay.
Proof of an onward or return ticket is often needed for all non-U.S. Citizens.
Immigration officials may ask for proof of sufficient funds to cover your stay.
No specific entry fees for tourists entering Saipan. Upon arrival, all travelers pass through U.S. Customs and Border Protection (CBP) inspection.
Standard health screenings may be in place as U.S. Health authorities determine. No specific vaccination certificates are universally needed.
Prices reflect the island's remote location and reliance on imports. The official currency is the United States Dollar (USD). Currency exchange services are at banks and some larger hotels. ATMs are widely available across the island, accepting major credit and debit cards.
These are estimates and can fluctuate based on season and individual choices.
Major credit cards (Visa, MasterCard, American Express) are widely accepted at hotels, larger restaurants, and shops. Some smaller local establishments or markets operate on a cash-only basis.
These price ranges give a general idea for planning your budget.
