Passport
Key Takeaways
A passport is a government-issued travel document that proves a traveler's identity and nationality, required for entry into most foreign countries and for re-entry into the traveler's home country. Many destinations require the passport to remain valid for at least six months beyond the planned departure date, a rule separate from the document's printed expiration date.
- U.S. passport processing runs 4-6 weeks for routine service and 2-3 weeks for expedited service as of April 2026, not counting mailing time [1].
- The U.S. issued a record 27.3 million passports in FY2025, driven by renewal demand and new international entry requirements [1].
- Navan's booking flow flags passport expiration dates that fall inside a destination's minimum-validity window before a traveler confirms an international trip.
- A passport proves who a traveler is; it does not by itself grant entry to a country. That permission, when required, comes from a visa or a passport control check at the border.
What Is a Passport?
Most passports are valid for five to ten years from the date of issue, though validity periods vary by country and, in some cases, by the age of the applicant. The passport itself does not grant permission to enter a foreign country. It establishes identity and nationality; a separate visa, when required, grants entry permission for a specific purpose and duration [2].

These three terms describe different steps in the same trip, and mixing them up causes real booking mistakes. A passport is the identity document itself. A visa is permission, often a stamp or digital record tied to that passport, that a destination country grants before or at arrival. Passport control is the physical checkpoint at a border where an officer inspects the passport, and any required visa, before allowing entry or exit.
Term | What It Is | Who Issues It | When a Traveler Encounters It |
|---|---|---|---|
Passport | Identity and nationality document | Traveler's home government | Applied for before any trip; carried on every international trip |
Visa | Entry permission for a specific country and purpose | Destination country's government | Applied for in advance, or granted on arrival, depending on the country |
Passport control | Border checkpoint that verifies the passport and visa | Destination or departure country's border agency | At the airport, land border, or port of entry, on arrival or departure |
A traveler can hold a valid passport and still be denied entry at passport control if the destination requires a visa the traveler does not have. Conversely, a valid visa is worthless without an accompanying passport that has not expired and meets the destination's minimum-validity requirement.
The Six-Month Validity Rule
Many countries will deny boarding or entry if a passport expires within six months of the travel dates, even though the passport itself is technically still valid on the day of travel. Airlines frequently enforce this rule at check-in on behalf of the destination country, since the airline can be fined for carrying a passenger who is later refused entry [2].
This rule catches business travelers more often than leisure travelers, since a passport renewed five years ago for a single trip can quietly slip past the six-month threshold without the traveler noticing until a same-week trip gets booked. Checking passport expiration against a specific destination's requirement, not just against the current date, is the safest way to avoid a denied boarding at the gate.

Best Practices for Managing Passports in a Business Travel Program
A travel program that treats passport validity as an individual traveler's problem discovers the gap at the worst possible time, usually a few days before a trip. A few habits prevent that.
When Passport Rules Intersect With Other Travel Documents
A passport rarely travels alone. Depending on the destination, a business traveler may also need one or more of the following, each governed by its own rules and application timeline.
A visa waiver program lets citizens of eligible countries enter certain destinations for short stays without a traditional visa, though it still requires a valid passport and, increasingly, a separate electronic travel authorization applied for in advance. Trusted traveler programs like Global Entry and TSA PreCheck speed up re-entry and domestic security screening for frequent travelers, but neither replaces the passport itself or waives any destination country's entry requirements.
The practical takeaway for a travel program is that passport validity is the baseline requirement, not the finish line. A corporate travel policy that only tracks passport expiration, without also flagging visa or entry-authorization requirements by destination, leaves a gap that shows up at passport control rather than at booking.
