The United States, Mexico, and the Dominican Republic require travelers to present a passport that remains valid for the period each country sets to authorize entry. Those who delay renewal may be prevented from boarding the flight or crossing the border.
The check applies both at airline check-in and at immigration checkpoints. Each nation sets its own minimum validity requirement, so the same passport may be valid for one destination and rejected in another. Checking the expiration date before buying tickets avoids setbacks.
What passport validity does each country require?
The requirements are not the same across the three destinations. The United States applies the six-month rule: the passport must remain valid beyond the planned stay, according to CBP.
Mexico does not legally require a fixed period, although some airlines still ask for six months as their own policy. The Dominican Republic generally keeps the six-month rule, but since December 2025 an exception has been in effect until the end of 2026 for certain countries.
Validity required by country
- United States: at least six months beyond the planned stay, with exceptions for certain nationalities.
- Mexico: no minimum period by law; it only needs to cover the length of the stay.
- Dominican Republic: six months in general, with an exception in effect until December 2026 for travelers from the European Union, the United Kingdom, the United States, Canada, Brazil, Chile, Argentina, Colombia, and Ecuador.
How this affects international travelers
A passport that does not meet the required margin can lead to denied boarding at the departure airport. It can also prevent entry upon arrival at the destination, even if the traveler has confirmed reservations.
That is why it is advisable to verify passport validity before booking the trip. If necessary, it is advisable to begin the renewal process several months in advance and confirm the requirements through each country’s official channels.
