Crossing the United States/Canada Border Into Montana

Our friends to the north: Are you planning a trip from Canada into Montana? We can’t wait to welcome you. Here's a quick guide to help your border crossing go smoothly.

What You'll Need at the Border

Valid Passport: Make sure your passport is valid for your full stay in the U.S. (six months beyond your travel dates is recommended). If you are crossing the border with minors, be sure to have notarized travel permission letters from their parents or legal guardians. If you are traveling solo with your children, be sure to bring a note of permission from the other parent. United States citizens under the age of 16 may use their birth certificate or naturalization certificate for travel between the United States and Canada.

Visa (if required)

Most Canadian citizens don't need a visa for short visits to the U.S., but double-check your eligibility if you're traveling with a non-Canadian passport.

Helpful Tips for a Smooth Entry

  • Have your itinerary handy. Border Patrol agents may ask about your destination, travel plans or past U.S. visits. Be honest and respectful when answering questions.
  • Declare agricultural products (snacks and other food items). Use this form: Customs Declaration Form 6059B
  • Limit cash: If you're carrying more than $10,000 USD (or equivalent), you'll need to declare it.
  • Skip the stress: Avoid bringing restricted items like certain fruits, plants or firewood.

Points of Entry

You’ll find 13 U.S. entry points from British Columbia, Alberta and Saskatchewan into Western Montana. For real-time border wait times, visit U.S. Customs and Border Protection at visit cbp.gov.
