Billings Entry Requirements
Visa, immigration, and customs information
Visa Requirements
Entry permissions vary by nationality. Find your category below.
The United States operates the Visa Waiver Program (VWP) for citizens of certain countries, while others must obtain a traditional visa before travel. All travelers should determine their specific requirements well before their planned departure date.
Citizens of VWP countries can enter the U.S. for tourism or business without obtaining a traditional visa
VWP travelers must have an e-Passport (electronic passport with chip), obtain ESTA authorization before travel, have a return or onward ticket, and meet all other admissibility requirements. Travel must be for business or tourism only.
Required pre-authorization for all VWP travelers before boarding flights to the U.S.
Cost: USD $21 per application
ESTA denials require applying for a traditional B-1/B-2 visa at a U.S. embassy or consulate. ESTA does not guarantee entry; final decision is made by CBP officer at port of entry.
All other nationalities and purposes of travel not covered by VWP require a traditional U.S. visa
Common visa types include B-1/B-2 (tourism/business), F-1 (student), J-1 (exchange visitor), H-1B (specialty worker). Start application process 2-3 months before intended travel. Canadians generally do not need visas for tourist visits but may need them for work or study.
Arrival Process
Upon arrival in the United States (whether at Billings or a connecting airport), all international travelers must complete immigration and customs procedures. If connecting through another U.S. city, you'll clear immigration at your first point of entry, then proceed through customs before any domestic connections.

Health Requirements
The United States has specific health requirements for entry, primarily focused on vaccination requirements for immigrants and certain visa categories. Health insurance is not mandatory for entry but strongly recommended due to high healthcare costs in the U.S.
Required Vaccinations
- COVID-19: As of May 2023, COVID-19 vaccination is no longer required for international travelers to the U.S. However, requirements can change; check current CDC guidelines before travel.
- Yellow Fever: Required only if arriving from a country with risk of yellow fever transmission. Vaccination certificate must be presented. Montana is not a yellow fever risk area.
Recommended Vaccinations
- Routine vaccinations: Ensure you're up to date on routine vaccines (MMR, DPT, Polio, etc.)
- Influenza: Especially during flu season (October-March)
- Hepatitis A and B: For longer stays
- COVID-19: While no longer required, vaccination is still recommended for health protection
Health Insurance
Health insurance is not required for tourist entry to the U.S., but is STRONGLY recommended. The U.S. has very high healthcare costs and medical treatment can be extremely expensive without insurance. Visitors should obtain comprehensive travel health insurance that covers medical treatment, hospitalization, and medical evacuation. Medicare and foreign health insurance typically do not cover care in the U.S.
Protect Your Trip with Travel Insurance
Comprehensive coverage for medical emergencies, trip cancellation, lost luggage, and 24/7 emergency assistance. Many countries recommend or require travel insurance.

Special Situations
Additional requirements for specific circumstances.
Children must have their own passport (including infants). Minors traveling without both parents should carry a notarized letter of consent from the non-accompanying parent(s) authorizing travel, including contact information. CBP may question children traveling with only one parent or with adults who are not their parents. Adoption papers or custody documents may be requested. Unaccompanied minors require special airline arrangements and documentation.
Dogs and cats: Must have rabies vaccination certificate (dogs must be at least 12 weeks old and vaccinated at least 30 days before entry). Health certificate issued by licensed veterinarian within 10 days of travel recommended. CDC suspended the dog importation ban from high-risk rabies countries in 2023, but check current rules. Birds: Require quarantine and permits from CDC and USDA. Other animals: Contact CDC and USDA-APHIS for specific requirements. Service animals have additional documentation requirements. Montana may have additional state requirements.
VWP visitors (ESTA) cannot extend their stay beyond 90 days and must leave the U.S. Those on B-1/B-2 visas can apply for extension using Form I-539 with USCIS, filed before current authorization expires. Extensions are not guaranteed and require valid reasons. For longer stays, consider appropriate visa categories (student F-1, work H-1B, etc.). Overstaying can result in deportation and future entry bans. Check your I-94 for authorized stay period.
Business visitors on VWP/ESTA or B-1 visa can attend meetings, conferences, negotiate contracts, but cannot perform work or receive U.S. salary. Bring invitation letters, conference registration, or business contact information. Samples and business equipment may require special customs documentation (ATA Carnet). Longer business assignments may require work visas (H-1B, L-1, etc.).
Students require F-1 visa (academic) or M-1 visa (vocational) with I-20 form from SEVIS-approved school. Exchange visitors need J-1 visa with DS-2019 form. Must prove intent to return home after studies. Can enter U.S. up to 30 days before program start date. SEVIS fee must be paid before visa interview. Dependents need F-2 or J-2 visas.
Canadian citizens generally do not need visas for tourist or business visits up to 6 months but must carry valid passport (or enhanced driver's license/NEXUS card at land borders). However, Canadians need visas for work, study, or other non-tourist purposes. Same customs and declaration requirements apply. Canadian permanent residents who are not citizens need appropriate visas or ESTA based on their nationality.
Even if only transiting through a U.S. airport to another country, most travelers need valid ESTA or visa. Some exceptions exist under limited transit programs. If leaving the airport during transit, full entry requirements apply. International-to-international transits still require clearing U.S. immigration.
