San Luis, Arizona - Travelers planning to cross into the U.S. through Arizona’s Port of San Luis for the upcoming holidays need to plan ahead and make sure they have proper documents in hand due to construction, advises Customs and Border Protection officials.

Border traffic increases significantly in the fall and winter months for agriculture imports and holiday travel. The Port of San Luis is undergoing construction that is expected to impact travelers entering the U.S. from Mexico.

“We will continue to monitor traffic during construction upgrades at the Port,” says Area Port Director John Schwamm. “We simply ask travelers to be patient.”

Schwamm also says travelers can help shorten the processing time by having their travel documents available to present to the primary officer, and by declaring everything they are bringing with them from Mexico.

CBP encourages travelers to pre-plan trips. Obtain a valid, acceptable travel document, such as a passport; a U.S. passport card; a trusted traveler card (NEXUS, SENTRI, Global Entry or FAST/EXPRES); a permanent resident card; or an enhanced driver’s license. Possession of these documents will expedite entry into the United States and make future border crossings more efficient.

To avoid potential delays at the border, CBP is urging all foreign travelers requiring I-94 or I-94W (visa waiver) entry document processing to obtain the essential document early instead of waiting until the day of their travel. Travelers are encouraged to obtain the required documents as much as a week in advance for faster and more convenient processing.

All travelers requesting an I-94 or I-94W entry document may be required to establish financial solvency and proof of residency outside the United States, and demonstrate that they have sufficiently strong ties to their country of origin, including a home abroad they do not intend to abandon.

1. Check out the new CBP informational website at cbp.gov.

2. Beat the border rush.

Cross during off-peak times, such as before 8 a.m. or after 5 p.m. Most lines at the border start building in the morning and carry on into early afternoon.

Monitor wait times on CBP’s Border Wait Times app. Information is updated hourly and is useful in planning trips and identifying periods of light use/short waits.

3. Keep travel documents handy.

4. Know the contents of your vehicle and be prepared to declare all items.

Travelers are required to declare all items being imported into the United States from Mexico. If you are not sure about what to declare, do not hesitate to ask.

5. Know what food products can be imported.

Many fruits, meats, dairy and poultry products are prohibited from being imported into the United States from Mexico.

For more information, see cbp.gov’s Prohibited and Restricted Items.

6. Firewood.

Only heat-treated firewood from Mexico is allowed into the United States. Personal importations of heat-treated firewood must be accompanied by either a treatment certificate or an attached commercial treatment label. Travelers attempting to bring untreated wood into the United States may be returned to Mexico to dispose of their wood there.
