Passport Requirements for Entering the United States: who needs a 6-month Validity period and Who is Exempt
The passport validity period required varies depending on the traveler's nationality. CBP maintains a list of countries whose citizens do not need an additional six months of validity.
Having a passport that hasn't expired isn't always enough to travel to the United States . For many foreign visitors, the document must remain valid for at least six months beyond their intended stay in the country. However, there is a long list of nationalities that are exempt from this requirement.
The difference lies in the so-called Six-Month Club , an agreement that allows citizens of certain countries to enter the United States with a passport valid only for the duration of their planned stay. The current list, published by Customs and Border Protection (CBP), was updated in December 2025.Geographic reference
This is not a new restriction adopted by airports like Miami, Orlando, New York, or Houston. The requirement is federal and is applied at U.S. ports of entry according to each traveler's nationality and documentation.Ethnic and identity groups
How many months must a passport be valid to enter the United States?
The State Department establishes as a general rule that a visitor's passport must be valid for at least six months beyond the intended period of stay in the United States, unless their nationality is covered by a specific exemption agreement.
For example, a person who plans to stay in the United States until October 15 should, as a general rule, have a passport valid for at least six additional months.Government agencies
But not all travelers are subject to that margin. CBP maintains a list of countries whose citizens only need their passport to remain valid for the duration of their intended stay.
Latin American countries exempt from the 6-month rule
Among the Latin American countries included by CBP on the exceptions list are:
- Argentina
- Bolivia
- Brazil
- Chili
- Colombia
- Costa Rica
- Dominican Republic
- El Salvador
- Mexico
- Nicaragua
- Panama
- Paraguay
- Peru
- Uruguay
- Venezuela
Spain is also among the countries benefiting from this exception.Travel and transport
This means, for example, that a Colombian, Mexican, or Dominican citizen is not subject to the general rule requiring another six months of validity after the intended stay, provided they meet the other corresponding immigration requirements.
The passport-related exception also does not mean that the person can remain indefinitely in the United States: the authorized period of stay is determined by CBP at the time of admission.
Who actually needs the six months?
For visitors of nationalities not listed on the exceptions list published by CBP, the general rule remains: the passport must be valid for at least six months beyond the intended stay in the United States.Visas and immigration
The list may be modified by the authorities, so it's advisable to check the most recent version before buying a flight or starting your trip .
There are also immigration situations and categories with specific documentation requirements. The instructions for an immigrant visa , for example, are not necessarily identical to those for a tourist traveling with a B1/B2 visa.

What happens if the passport expires during the trip?
It depends on nationality. For those from one of the countries included in the Six-Month Club, the exception allows them to forgo the additional six months, but their passport must remain valid for the intended period of stay.Geographic reference
Therefore, having a document that expires before the scheduled date to leave the United States can cause problems even if the traveler belongs to one of the exempt countries.
For those who do not have the exception, the required margin is longer and the six-month rule must be respected.
Can the airline prevent a passenger from boarding the plane?
Immigration documents are checked even before arrival in the United States. Airlines review the necessary travel documents and can deny boarding if a passenger does not meet the destination's entry requirements.Ethnic and identity groups
For this reason, a passport expiration issue can be detected before arriving at a U.S. airport. This does not mean that Miami, New York, Houston, or Orlando have established any particular passport rules.
What happens if the US visa is in an expired passport?
There is a very useful exception for those who recently renewed their passport. The State Department confirms that a valid U.S. visa placed in an expired passport can still be used. In that case, the traveler can carry both the old passport containing the visa and the new, valid passport.Government agencies
Both documents must correspond to the same nationality and the visa must be valid, undamaged and appropriate for the purpose of the trip.
Authorities warn that the visa should not be removed or physically transferred from the old passport to the new one, because doing so may invalidate it.
Does having a valid visa and passport guarantee entry?
No. A valid visa allows a foreign national to present themselves at a U.S. port of entry and request admission. The final decision rests with a Customs and Border Protection (CBP) officer, who also determines how long the person can remain in the country.Travel and transport
Therefore, there are three dates that should not be confused: the passport expiration date, the visa validity period, and the period of stay authorized by CBP.
And who travels with ESTA?
Citizens using the Visa Waiver Program (VWP) must have an electronic passport and a valid ESTA authorization.
The State Department also points out the six-month rule after the planned departure from the United States, except for citizens benefiting from specific validity exemption agreements.
Therefore, having an approved ESTA does not replace passport requirements.Visas and immigration
Before traveling, the safest recommendation is to check both the exact expiration date of the document and the current list of CBP exceptions, especially if the passport has only a few months of validity remaining.
