Portland Entry Requirements
Visa, immigration, and customs information
Information last reviewed March 2026. U.S. immigration and visa policies change frequently. Always verify current requirements with the U.S. Department of State (travel.state.gov) and your country's embassy or consulate before traveling.
Visa Requirements
Entry permissions vary by nationality. Find your category below.
Entry to the United States, and by extension Portland, is governed by U.S. federal immigration law. The key framework is the Visa Waiver Program (VWP), which allows citizens of 42 designated countries to visit the U.S. for up to 90 days without a visa, provided they obtain prior authorization via ESTA. Citizens of all other countries must apply for a visa at an U.S. embassy or consulate before traveling.
Citizens of VWP-designated countries do not need a traditional visa for tourism, transit, or short business visits. But MUST obtain an approved Electronic System for Travel Authorization (ESTA) before boarding any carrier to the U.S. ESTA is not a visa, it is a pre-travel authorization that determines eligibility to travel under the VWP.
Cost: USD $21 per application (includes a $4 processing fee and $17 authorization fee). Only charged if approved.
Travelers with prior U.S. visa denials, criminal records, or who have visited Cuba, Iran, Iraq, Libya, North Korea, Somalia, Sudan, Syria, or Yemen on or after March 1, 2011, are ineligible for VWP travel and must apply for a B-2 tourist visa regardless of nationality. ESTA does not guarantee entry, CBP officers make the final determination at the port of entry. Travel on a VWP waiver does not allow an extension of stay.
Citizens of countries not included in the VWP, or VWP nationals who are ineligible due to prior travel history or other factors, must obtain a B-1 (business) or B-2 (tourism) visa before traveling to Portland or anywhere in the U.S. This requires an in-person interview at an U.S. embassy or consulate in the applicant's home country.
Cost: USD $185 non-refundable application fee (MRV fee) for most nonimmigrant visas, paid before the interview.
A visa does not guarantee entry, CBP officers make the final decision at the port of entry. Visa denial rates vary significantly by nationality and individual circumstances. Having a prior U.S. visa significantly improves approval chances. Apply well in advance, as embassy interview slots can be scarce in many countries.
U.S. citizens and lawful permanent residents (green card holders) are not subject to immigration controls upon returning to the U.S. and may use dedicated CBP lanes or automated passport control kiosks.
U.S. citizens must present a valid U.S. passport when entering from abroad. Permanent residents must present their green card (Form I-551). Passports must be valid, the U.S. does not require six months' validity beyond the date of entry for its own citizens. But airlines may have their own rules.
Canadian citizens enjoy expedited entry to the U.S. under the bilateral relationship between the two countries. No visa is required, and no ESTA is required (ESTA applies only to VWP countries traveling by air or sea).
While Canadians do not need a visa or ESTA, they are still subject to CBP inspection upon arrival and must satisfy the officer that they qualify for admission. Canadians with criminal records (including DUI) may be denied entry.
Arrival Process
Most international visitors to Portland will arrive at Portland International Airport (PDX), which handles the full U.S. immigration and customs process on-site. Travelers arriving on connecting U.S. domestic flights from another international gateway (e.g., Los Angeles, San Francisco, Seattle) will have already cleared customs at that first point of entry and simply transit to Portland domestically. Here is what to expect if PDX is your first U.S. port of entry.
Documents to Have Ready
Tips for Smooth Entry
Customs & Duty-Free
U.S. Customs and Border Protection (CBP) enforces customs rules at Portland International Airport and all other U.S. ports of entry. CBP is strict about agricultural products due to the risk of introducing pests and diseases to American agriculture. Portland's proximity to major agricultural regions in Oregon makes agricultural enforcement important at PDX.
Prohibited Items
- Most fresh fruits, vegetables, and plants, risk of introducing agricultural pests. Many items that are legal to bring into other countries are prohibited here
- Meats and poultry from countries with foot-and-mouth disease or other livestock diseases, CBP and USDA enforce strict restrictions
- Soil and certain plant materials, agricultural biosecurity risk
- Endangered species and products made from them (ivory, certain leathers, feathers), CITES treaty enforcement
- Counterfeit goods, trademark and copyright violation. Goods can be seized and fines imposed
- Cuban cigars (exceeding personal use quantities or imported commercially), though personal quantities for personal use are now permitted
- Drug paraphernalia, even if legal in Oregon (where cannabis is recreationally legal, it remains federally illegal and cannot be brought into the U.S.)
- Narcotics and controlled substances not declared and authorized, federal law applies regardless of state cannabis laws
- Firearms without prior ATF approval, prior import authorization required. No firearms may be brought through customs without compliance with federal ATF and CBP requirements
- Items from sanctioned countries (North Korea, Cuba with exceptions, Iran, Syria) that are subject to OFAC restrictions
Restricted Items
- Firearms, may be imported with prior ATF Form 6 approval. Must be declared to CBP at arrival. Subject to federal and Oregon state registration requirements
- Ammunition, limited quantities for personal use. Must be declared
- Alcohol above duty-free limits, dutiable and subject to Oregon state excise tax. Commercial quantities require import licensing

- Seeds, some permitted with USDA APHIS permit. Others prohibited; must declare all seeds
- Pets and animals, subject to CDC and USDA import rules. Dogs must have documentation of rabies vaccination and health certificate. No declaration of pets means no entry
- Cultural artifacts and antiquities, may require export documentation from country of origin. Import restrictions under U.S. law
Health Requirements
The United States does not impose blanket vaccination requirements on most international travelers. But there are specific requirements for certain visa categories and originating countries, and strong recommendations for all visitors. Portland's healthcare system is excellent. But medical costs in the U.S. are extremely high without insurance, travel health insurance is strongly recommended.
Required Vaccinations
- No vaccinations are universally required for tourist entry to the United States for most travelers.
- Immigrants and certain long-term visa applicants (not tourists) must show proof of vaccination against: mumps, measles, rubella, polio, tetanus and diphtheria toxoids, pertussis, Haemophilus influenzae type B, hepatitis A, hepatitis B, varicella, pneumococcal disease, influenza, COVID-19, meningococcal disease, and rotavirus, this applies to visa-category immigration medical exams, NOT standard tourist entry.
- Some originating countries with active disease outbreaks may have temporary vaccination requirements, check CDC and State Department advisories for your specific country of origin before traveling.
Recommended Vaccinations
- Routine vaccinations: Ensure all standard childhood vaccinations are up to date (MMR, DPT, polio, varicella, influenza).
- COVID-19: No longer required for entry as of May 2023, but vaccination is recommended by the CDC for all eligible travelers.
- Flu vaccine: Recommended, for travel during October, April (Portland's flu season coincides with fall/winter).
- Hepatitis An and B: Recommended for most international travelers regardless of destination.
- Consult a travel medicine physician or your GP 4, 6 weeks before travel to review your personal vaccination status.
Health Insurance
The United States has no universal public healthcare system. Medical treatment, even a brief emergency room visit, can cost thousands of dollars without insurance. Travel health insurance that covers emergency medical treatment, hospitalization, and medical evacuation is STRONGLY recommended for all visitors to Portland. Ensure your policy is valid in the U.S., has adequate coverage limits (minimum USD $100,000 recommended), and covers any pre-existing conditions you have. Some countries' domestic health insurance (e.g., UK NHS, European EHIC) does NOT provide coverage 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 traveling with both parents need no additional documentation beyond their own valid passport (and ESTA or visa if applicable). Children traveling with ONE parent or with a non-parent guardian should carry a notarized letter of consent from the absent parent(s) authorizing the trip, including destination, dates, and the guardian's contact information. While not always legally required at U.S. entry, CBP officers may ask for it and airlines often require it to board. Children born in the U.S. are U.S. citizens regardless of parents' nationality and should travel on an U.S. passport. Minors on immigrant visas must have the same health examination as adults.
Dogs entering the U.S. must be healthy in appearance. Dogs vaccinated against rabies in the U.S. may re-enter freely. Dogs vaccinated outside the U.S. must have a valid rabies certificate showing vaccination at least 12 days before arrival. Dogs from countries classified by the CDC as 'high risk' for dog rabies face additional requirements including microchipping and health documentation. Cats face minimal import restrictions but must appear healthy. Other pets (birds, reptiles, small mammals) face varying restrictions enforced by USDA and U.S. Fish and Wildlife, check species-specific requirements well in advance. All pets must be declared on the CBP Declaration Form. Oregon state does not add requirements beyond federal rules for standard companion animals.
Tourists admitted under the VWP are admitted for exactly 90 days and CANNOT extend their stay under any circumstances, they must depart by the date on their I-94 record. Tourists on B-2 visas may apply to USCIS for an extension of stay (Form I-539) before their current authorized period expires, for up to 6 additional months. Approval is not guaranteed. Working, studying, or engaging in activities outside the permitted scope of a tourist visa while in Portland is a serious violation that can result in removal and bars on future entry. If extended stays are contemplated, investigate the appropriate visa category (F-1 student, H-1B work, O-1 talent, etc.) before traveling.
The U.S. applies strict inadmissibility grounds to travelers with certain criminal convictions, arrests, or associations. Even arrests without conviction can affect entry. Crimes involving 'moral turpitude,' drug offenses, and prior immigration violations are the most common grounds for denial. VWP travelers with qualifying criminal history are ineligible for ESTA and must apply for a B-2 visa, which may itself be denied. Consult an U.S. immigration attorney before booking travel if you have any criminal record, including DUI/DWI, which Canada and the U.S. both treat as potential grounds for inadmissibility.
The U.S. periodically imposes entry restrictions, enhanced vetting, or suspensions on nationals of certain countries. These policies change based on security assessments, diplomatic relations, and Congressional or executive action. As of early 2026, check the U.S. Department of State and DHS websites for current country-specific restrictions. Travelers from affected countries may still apply for waivers of inadmissibility in some circumstances, an immigration attorney can advise on this.
The United States does not formally recognize dual citizenship. But does not prohibit it. U.S. citizens who hold a second citizenship must enter and exit the U.S. on their U.S. passport, using a foreign passport to enter is not permitted and can create immigration complications. Dual nationals who are also citizens of countries subject to VWP restrictions or travel bans should seek legal advice before traveling.
