Each year, airports and land ports record a massive flow of travelers seeking to visit relatives or discover iconic tourist destinations.

What Are the Mandatory and Essential Documents You Must Present at the Border?
To enter the United States for recreational purposes, every Mexican citizen must mandatorily present two documents in physical format and good condition. First and foremost, it is essential to have a valid Mexican passport, which must be of the electronic or biometric type. The guidelines of Mexico’s Ministry of Foreign Affairs stipulate that this document must have a minimum validity of 6 months. This period is calculated from the estimated date of entry into U.S. territory to guarantee a protected legal stay.
The second indispensable requirement is the B1/B2 non-immigrant visa, which must be stamped physically in the passport. CBP authorities constantly reiterate that there are no valid digital or electronic versions for this type of tourist visa. Any document that presents strikeouts, amendments, or detached pages will be immediately rejected by border personnel. Likewise, every person over 7 years of age must exhibit their own individual documentation to cross control points.
| Mandatory Document | Required Format | Required Validity | Physical State of Document |
| Mexican Passport | Electronic / Biometric | Minimum 6 months upon entry | Excellent, without alterations or damage |
| B1/B2 Visa | Stamped in the passport | Valid during entire stay | Legible, barcode intact |
