If you’re a U.S. citizen flying to Guam, the good news is you don’t need a visa or any electronic travel authorization — Guam is U.S. territory, and travel from the mainland or Hawaii is domestic travel. That said, there are still two things worth knowing before you fly: your ID requirements, and a mandatory customs form that catches many first-time visitors off guard.
No Visa or ETA Required for US Citizens
The Guam-CNMI Visa Waiver Program and its associated “Guam-CNMI ETA” (mandatory as of November 29, 2024) apply to foreign visitors from the 12 eligible countries and territories — not to U.S. citizens or lawful permanent residents. If you’re flying from the U.S. mainland, Hawaii, or another U.S. territory, you don’t need to apply for anything before you go, aside from having acceptable identification.
ID Requirements: REAL ID Isn’t the Only Option
As with any domestic U.S. flight, you’ll need acceptable identification at airport security. A REAL ID-compliant driver’s license or state ID works, but it isn’t the only option — a valid U.S. passport, U.S. passport card, permanent resident card, DHS trusted traveler card, an Enhanced Driver’s License (EDL), and several other TSA-listed credentials are also accepted. If your state-issued ID isn’t REAL ID-compliant, bringing your passport is a straightforward alternative. Check the current TSA accepted ID list if you’re unsure.
The Part Many US Travelers Miss: Guam’s Electronic Declaration Form (EDF)
Guam maintains its own agricultural and customs boundary, separate from the rest of the United States, because of its unique island ecosystem. That means every arriving passenger — including travelers coming from the U.S. mainland — must complete Guam’s Electronic Declaration Form (Guam EDF) before or on arrival.
As of February 4, 2025, the paper customs declaration card has been discontinued entirely. There’s no form to fill out on the plane anymore — it’s electronic-only.
- Where to complete it: guamedf.landing.cards (also linked from the Guam Customs and Quarantine Agency site, cqa.guam.gov)
- When you can submit it: Up to 72 hours before your scheduled arrival in Guam (not your departure time)
- Who needs it: Every arriving passenger, regardless of citizenship or where you’re flying from
- Language: English only
- How many per group: One submission covers a single family unit living in the same household (related by blood, marriage, domestic partnership, or adoption). Travel companions outside your immediate family must each submit their own form
Because it’s easy to assume a flight from the mainland is “just another domestic flight” with no customs involved, this is the step travelers most often overlook. If you don’t complete it in advance, kiosks are available in the baggage claim area at Guam’s airport — but submitting it before you leave for the airport will save you time and avoid arrival-hall lines.

Pre-Departure Checklist
- Confirm you’re carrying an ID accepted by TSA — a REAL ID-compliant license, a valid passport, or another accepted credential
- Complete Guam’s Electronic Declaration Form (Guam EDF) within 72 hours of your scheduled arrival
- Check whether your travel companions are part of your household (one EDF) or need to submit separately
- Save a screenshot or confirmation of your completed EDF submission
- If you’re arriving with agricultural products, plants, or certain food items, double-check Guam’s restrictions before you pack
Frequently Asked Questions
Do I need an ETA or visa to fly to Guam as a U.S. citizen?
No. The Guam-CNMI ETA applies to foreign visitors from the 12 eligible Guam-CNMI Visa Waiver Program countries and territories, not to U.S. citizens or permanent residents traveling domestically.
Do I need a REAL ID to fly to Guam?
Not necessarily. A REAL ID-compliant license works, but so does a valid U.S. passport, passport card, or several other TSA-accepted forms of ID. Check the TSA’s current list if you’re unsure which of your documents qualify.
Do I still need to fill out a customs form if I’m flying from the U.S. mainland?
Yes. Guam has its own agricultural and customs boundary, so every arriving passenger — domestic or international — must complete the Guam Electronic Declaration Form (Guam EDF) before or on arrival. There’s no paper form anymore; it’s done online.
Can I fill out the EDF on the plane?
No, the paper form was discontinued on February 4, 2025. Complete it online up to 72 hours before your scheduled arrival, ideally before you leave for the airport. If you miss that window, kiosks at the Guam airport baggage claim area let you complete it after landing.
Does everyone in my group need to submit a separate EDF?
Only one EDF is needed per family unit living in the same household. Anyone traveling with you who isn’t part of that household needs to submit their own form.
Summary
Flying to Guam as a U.S. citizen is straightforward — no visa, no ETA — but don’t skip Guam’s Electronic Declaration Form just because the flight feels domestic. Bring a TSA-accepted form of ID, complete the EDF online in the 72 hours before you land, and you’re set.
