Yellowstone National Park Entry Requirements

Visa, immigration, and customs information

Yellowstone National Park is located within the United States of America. All international travelers must comply with U.S. federal entry requirements, as Yellowstone itself does not have separate immigration controls. Entry to the U.S. involves passing through U.S. Customs and Border Protection (CBP) at an official port of entry, such as an international airport or land border crossing. Before traveling, visitors must determine their visa requirements based on their nationality and purpose of visit, ensuring their passport is valid for at least six months beyond their intended stay. Upon arrival, travelers will be processed by CBP officers who will inspect travel documents, ask questions about the visit, and determine admissibility. It is important to understand that entry to Yellowstone National Park requires entry to the United States first. The park has an entrance fee, but this is separate from federal immigration procedures. Travelers should carry proof of their travel plans, including accommodation bookings and return/onward tickets, as CBP may request this information. Overstaying a visa or violating the terms of admission can result in deportation and future inadmissibility. Planning is essential, as visa applications can take considerable time. All visitors should verify current entry rules directly with official U.S. government sources, as policies can change. This guide provides a general framework, but the ultimate authority on entry rests with U.S. CBP officers at the port of entry.

Visa Requirements

Entry permissions vary by nationality. Find your category below.

Visa requirements for Yellowstone are the same as for the United States. The U.S. Visa Waiver Program (VWP) allows citizens of certain countries to travel for tourism or business for stays of 90 days or less without obtaining a visa.

Visa-Free Entry

90 days maximum

Citizens of Visa Waiver Program (VWP) countries can enter without a visa for tourism/business if they obtain an approved ESTA prior to travel.

Includes

United Kingdom Germany France Italy Spain Netherlands Sweden Norway Denmark Finland Ireland Australia New Zealand Japan South Korea Singapore Taiwan Chile

Must have an e-passport, an approved ESTA authorization, and a return/onward ticket. Travelers with a criminal record or who have visited certain countries (like Iran, Iraq, Syria, etc.) since March 2011 may not be eligible for ESTA.

Electronic Travel Authorization (ETA/eVisa)

90 days maximum (tied to VWP)

The Electronic System for Travel Authorization (ESTA) is a mandatory pre-authorization for VWP travelers.

Includes

All Visa Waiver Program countries (see list above)

How to Apply: Apply online via the official ESTA website. Apply at least 72 hours before travel, though approval is often quicker. It is valid for two years or until passport expiry.
Cost: $21 USD

An approved ESTA is not a guarantee of entry; the final decision is made by a CBP officer at the port of entry. You must apply for ESTA even if transiting through the U.S.

Visa Required

Determined by CBP officer at entry, typically up to 6 months

Citizens of countries not in the Visa Waiver Program must apply for a nonimmigrant visa (typically B-2 for tourism) at a U.S. embassy or consulate.

How to Apply: Schedule an interview at the nearest U.S. embassy/consulate. The process involves completing the DS-160 form, paying the visa fee, and providing supporting documents (proof of ties to home country, financial means, travel itinerary). Processing times vary widely by location.

Canadian citizens generally do not require a visa for tourist visits. Mexican citizens traveling to border regions may have different rules; for travel to interior states like Wyoming, a visa is typically required.

Arrival Process

Upon arrival at a U.S. port of entry (e.g., airports like Salt Lake City, Bozeman, or land borders), all travelers must clear U.S. Customs and Border Protection (CBP).

Primary Inspection

Present your passport, visa or ESTA approval, and completed CBP Form 6059B (Customs Declaration) to a CBP officer. The officer will ask about the purpose of your visit, length of stay, and destination.

Biometrics Collection

Most visitors will have their photograph and fingerprints taken digitally at the primary inspection booth.

Secondary Inspection (if required)

If the CBP officer needs more information, you may be directed to a secondary inspection area for further questioning and document review.

Admission Decision

The CBP officer will stamp your passport and issue an electronic Form I-94 (Arrival/Departure Record) noting your visa class and admitted-until date. You can retrieve your I-94 online after entry.

Collect Baggage & Customs Check

After immigration, collect your checked baggage and proceed through customs, where you may be asked to declare items or have your bags inspected.

Documents to Have Ready

Valid Passport

Required for all travelers. For VWP travelers, must be an e-passport (with chip). Must be valid for at least six months beyond your intended period of stay.

Visa or ESTA Approval

Required based on nationality. ESTA approval must be obtained before boarding a carrier to the U.S.

Proof of Ties to Home Country

CBP may ask for evidence of employment, property, or family to show you intend to return home (e.g., letter from employer, property deed).

Proof of Financial Means

Evidence you can financially support yourself during your stay (e.g., bank statements, credit cards).

Travel Itinerary

Details of your trip, including return/onward ticket, hotel reservations, and tour bookings (like for Yellowstone).

Tips for Smooth Entry

Have all your documents (passport, ESTA/visa, itinerary, proof of funds) organized and easily accessible for the CBP officer.

Answer all questions clearly, honestly, and concisely. Do not joke or provide unnecessary information.

Print copies of your important documents (ESTA approval, hotel bookings, travel insurance) in case of electronic device failure.

If you do not speak English, you may request an interpreter. Carrying a simple note explaining your travel plans in English can be helpful.

After entry, download and save your electronic I-94 form from the CBP website. You may need it for future visa applications or to prove legal status.

Customs & Duty-Free

All travelers must declare items they are bringing into the United States. Strict rules apply to agricultural products, wildlife items, and large amounts of currency.

Alcohol

1 liter (33.8 fl oz) per person aged 21 or over.

State laws may further restrict amounts. You must declare quantities over this limit.

Tobacco

200 cigarettes, OR 100 cigars (non-Cuban), OR 2 kilograms of smoking tobacco.

Restrictions apply to Cuban cigars. Additional taxes apply for amounts over the allowance.

Currency

No limit on amount you may bring in or take out.

You must file a FinCEN Form 105 if you are carrying more than $10,000 USD (or foreign equivalent) in monetary instruments.

Gifts/Goods

$800 USD personal exemption per person.

Items intended as gifts can be included in this exemption. Goods valued above $800 are subject to duty and tax.

Prohibited Items

Absinthe - contains thujone, which is prohibited
Counterfeit or pirated goods - illegal under U.S. law
Cultural artifacts or wildlife products without proper permits - violates international treaties (CITES)

Health Requirements

The U.S. does not require specific vaccinations for general tourist entry. However, health recommendations are in place for the safety of travelers and public health.

Required Vaccinations

None for general tourism from most countries.

Recommended Vaccinations

Routine vaccinations (MMR, diphtheria-tetanus-pertussis, varicella, polio, flu)
COVID-19 vaccination (recommended but not required for entry)
Rabies (for those who might have contact with animals)

Health Insurance

The U.S. does not require health insurance for entry. However, medical care in the U.S., including emergency services, is extremely expensive. Travelers are strongly advised to purchase complete travel health insurance that covers medical evacuation. Hospitals in gateway towns near Yellowstone (e.g., Bozeman, Billings, Jackson) will treat emergencies but will bill the patient.

Current Health Requirements: As of October 2024, there are no COVID-19 testing, vaccination, or quarantine requirements for air travelers entering the United States. However, requirements can change; always check the CDC website for the latest travel health notices.

Special Situations

Traveling with Children

Children, regardless of age, must have their own passport. If a child is traveling with only one parent, with neither parent, or with adults who are not parents/legal guardians, it is strongly recommended to carry a notarized letter of consent from the absent parent(s) detailing the travel plans and granting permission. This is not a U.S. law but can be requested by CBP to prevent child abduction.

Traveling with Pets

Dogs must be vaccinated against rabies at least 30 days before entry (proof required). A maximum of two pets per person are allowed. Pets are allowed in certain areas of Yellowstone National Park but must be leashed at all times (max 6-foot leash) and are prohibited from trails, boardwalks, and backcountry. Service animals are exempt from some restrictions. Cats entering the U.S. are not required to have proof of rabies vaccination but it is recommended. Check USDA APHIS for latest rules.

Extended Stays

You cannot extend a stay granted under the Visa Waiver Program (ESTA). You must depart the U.S. before your 90-day admission expires. For those on a B-2 tourist visa, you may apply to U.S. Citizenship and Immigration Services (USCIS) for an extension (Form I-539) before your current I-94 expires, but you must demonstrate compelling reasons. Overstaying any visa or admission period is a serious violation and can lead to deportation and future bans on entry.
