You cannot fly internationally with an expired U.S. passport. Airlines check documents at the gate and will refuse to board you, even on a flight home to the United States. If you are already abroad when your passport expires, the fix is an emergency passport from the nearest U.S. embassy or consulate, often issued within a day or two. If you are still at home, renew before you go.
Why Airlines Refuse to Board You
Airlines enforce the entry rules of your destination, and they face fines if they carry a passenger without valid documents. For U.S. citizens flying back to the United States, Customs and Border Protection requires a valid U.S. passport to board. An expired book gets you turned away at check-in regardless of your citizenship.
Many countries add a further requirement known as the six-month validity rule: your passport must remain valid for at least six months beyond your planned stay. A passport that has not technically expired can still get you refused boarding or turned around at immigration if it falls inside that window. CBP applies the same rule to visitors coming into the United States.
Your Right to Enter Versus the Airline’s Gate
The government cannot permanently deny a U.S. citizen entry to the country. Under 8 U.S.C. § 1185(b), entering or leaving the U.S. without a valid passport is technically unlawful, but the statute allows exceptions for unforeseen individual emergencies.1Office of the Law Revision Counsel. 8 USC 1185 – Travel Control of Citizens and Aliens If a citizen somehow arrives at a port of entry with an expired passport, CBP will verify citizenship by other means and admit the person, though expect long delays and questioning. The real barrier is not the border. It is the airline counter, where no boarding pass gets printed without a valid document.
Getting an Emergency Passport Abroad
If your passport expires while you are overseas, contact the nearest U.S. embassy or consulate for a limited-validity emergency passport. Consular officers typically limit the validity to the minimum time needed to reach the United States, with a general maximum of one year depending on the circumstances.2U.S. Department of State. 8 FAM 505.2 Passport Endorsements
You need an appointment. Walk-ins are generally not available, but if no slot appears before your flight, contact the embassy directly and ask for an emergency appointment.3U.S. Consulate General Curacao and U.S. Mission to the Dutch Caribbean. Emergency Passports A consular officer reviews your documents, has you sign the application in person, and may ask a few questions to confirm the urgency. Emergency passports are often issued the same day or within one to two business days.
What to Bring to Your Appointment
- Form DS-11, completed online and printed with the barcode. Do not sign it until instructed. If your passport was lost or stolen, add Form DS-64.4U.S. Department of State. Passport Forms
- Proof of citizenship: an original birth certificate, your expired U.S. passport, a Consular Report of Birth Abroad, or a Certificate of Naturalization. The officer may also be able to verify a prior passport record electronically.
- A valid government-issued photo ID such as a driver’s license.
- Two recent 2×2-inch color passport photos with a white background. Confirm specifics with the embassy, since requirements vary slightly.5U.S. Embassy in the Dominican Republic. Emergency or Limited Validity Passport
- A confirmed flight itinerary showing your departure date.
- Payment. The passport book application fee is $130 plus a $35 acceptance fee, totaling $165. Expedited service adds $60. Accepted payment methods vary by post.6U.S. Department of State. Passport Fees
Emergency Passports for Children
Children under 16 cannot renew. Every child’s passport application uses Form DS-11, even if the previous one just expired.7U.S. Department of State. Renew Your Passport by Mail Both parents or legal guardians generally need to appear in person with the child. When one parent cannot appear, that parent must provide a notarized Form DS-3053 (Statement of Consent). If the absent parent cannot be located at all, the applying parent completes Form DS-5525 instead, explaining the circumstances.8USEmbassy.gov. DS-11 / DS-3053 – Wizard Results
For military families where the non-applying parent is deployed, a notarized DS-3053 is the standard route. If the deployed parent is entirely unreachable, submit either military orders showing a special assignment longer than 30 days or a signed statement from the commanding officer confirming the parent cannot be contacted. An expired child’s passport, if it was full-validity and undamaged, still works as proof of citizenship for the new application.
Countries That Won’t Accept an Emergency Passport
A limited-validity emergency passport will get you back to the United States, but it may not get you through transit countries along the way. France, for instance, does not recognize the 12-page U.S. emergency passport for visa-free entry. French border officials can refuse you, and the airline can deny boarding. The only exception is direct transit through France to the United States.9U.S. Embassy & Consulates in France. EPDP Travel to France
France is the most documented example, but other countries may have similar restrictions. Before booking connections, check the entry and transit rules for every country on your itinerary. Book a direct flight home when you can. The consular officer issuing your emergency passport can often flag known problems in the region.
Crossing a Land or Sea Border
The rules loosen a bit for land crossings and cruise arrivals. Under the Western Hemisphere Travel Initiative, U.S. citizens returning by land or sea can use documents other than a passport book:10U.S. Customs and Border Protection. Western Hemisphere Travel Initiative
- A U.S. passport card, valid for land and sea travel to Canada, Mexico, Bermuda, and parts of the Caribbean. Not valid for air travel.11U.S. Department of State. Get a Passport Card
- An enhanced driver’s license, issued by certain states.
- A trusted traveler card such as NEXUS, SENTRI, or Global Entry.
- A military ID with travel orders for service members on official business.
If your passport book is expired but you hold a valid passport card or enhanced driver’s license, you can still cross a land border from Canada or Mexico. Children 15 and under arriving by land or sea from Canada or Mexico can present just a birth certificate.12U.S. Customs and Border Protection. U.S. Citizens – Documents Needed to Enter the United States Closed-loop cruises that begin and end at the same U.S. port have their own relaxed rules; confirm directly with the cruise line.
Renew Before You Leave if You Still Can
If you are still stateside, the cleanest fix is to renew now. You can renew by mail on Form DS-82 if your most recent passport was issued within the last 15 years, was issued when you were 16 or older, is undamaged, has never been reported lost or stolen, and is in your current name (or you can document a name change).7U.S. Department of State. Renew Your Passport by Mail Routine processing runs 4 to 6 weeks. Expedited runs 2 to 3 weeks for an extra $60. Neither timeframe includes mailing, which can add roughly two more weeks.13U.S. Department of State. How to Get My U.S. Passport Fast
If your trip is sooner than that, U.S. passport agencies and centers take in-person appointments for travelers leaving within 14 calendar days.14U.S. Department of State. Make an Appointment at a Passport Agency or Center For a life-or-death emergency involving the death, imminent death, or life-threatening illness or injury of an immediate family member abroad, and travel within the next two weeks, call the State Department’s emergency line at 202-647-4000 after hours (after 8 p.m. ET and on weekends and federal holidays).15U.S. Department of State. Get a Passport if you Have a Life-or-Death Emergency Immediate family for this purpose means a parent, child, spouse, sibling, or grandparent. Aunts, uncles, and cousins do not qualify.
Dual Citizens: No Workaround With the Other Passport
Holding a second nationality does not solve the expired-passport problem. Federal law requires U.S. citizens to enter and leave the United States on a U.S. passport. The State Department is direct: dual nationals “must enter and leave the United States on your U.S. passport” and are “not allowed to enter on your foreign passport based on U.S. law.”16Travel.State.Gov. Dual Nationality Dual citizens are also not eligible for a U.S. visa, so there is no alternative entry document. You will still need either a renewed U.S. passport or an emergency one issued abroad.
Replace Your Emergency Passport Once You’re Home
A limited-validity passport is a stopgap. Some countries reject it, and it will not serve you the way a full-validity book does on future trips. Replace it after you get back.
If your emergency passport was issued less than a year ago, check the letter that came with it for whether to use Form DS-11 or Form DS-5504. You submit the limited-validity passport and one new photo, and no application fees apply unless you want expedited service.17U.S. Department of State. Replace a Limited Validity Passport If more than a year has passed, apply on Form DS-11 or DS-82 (if you qualify to renew by mail), submit the limited-validity passport and a photo, and pay the full fees.
