What Documents Do I Need to Cross Into the United States? Full Checklist

Personal documents

If you are a Mexican citizen traveling for tourism, shopping or business, the basics are:

• Valid Mexican passport.
• Valid B1/B2 visa, or Border Crossing Card (laser visa). The laser visa lets you cross by land within the border zone; if you fly, you will also be asked for your passport.
• I-94 permit, only if you are going beyond the border zone or staying longer than 30 days. We explain when in the I-94 guide.

If you are a US lawful permanent resident, cross with your green card. US citizens return with a passport, passport card or Enhanced Driver's License.

If you cross by car

• Valid driver's license. A Mexican license works for temporary visits.
• Vehicle registration card (tarjeta de circulación).
• Insurance with coverage in the United States. Mexican insurance usually does not cover you on the other side. Read the car insurance guide.
• If the car is not in your name, a letter from the owner with a copy of their ID.
• If the car is financed, check that your contract allows you to take it out of the country.

Minors

Minors need their own passport and visa or Border Crossing Card. If they travel with only one parent or with another adult, bring an authorization letter signed by the parents who are not traveling, with copies of their IDs. It is not always requested, but it avoids problems.

Pets

Dogs must appear healthy. CBP and the CDC have rules for dogs coming from other countries, which may include a microchip, a minimum age and a form. Check the current CDC requirements before traveling with your dog. Cats have fewer requirements, but they must also appear healthy.

Before you leave

1. Check that none of your documents are expired or damaged.
2. Keep them within reach, not in the trunk.
3. Check the wait time at your border crossing.
4. If you are bringing products, check what you can bring across.
