Visa, immigration, and customs information
Visa Requirements
Entry permissions vary by nationality. Find your category below.
The United States operates several visa programs depending on nationality and purpose of visit. Citizens of certain countries can enter visa-free under the Visa Waiver Program (VWP), while others must obtain either an Electronic System for Travel Authorization (ESTA) or a traditional visa before travel.
Citizens of 41 countries can travel to the U.S. for tourism or business without a visa, but must obtain ESTA authorization before departure
Cost: USD $21 per application
Travelers must have an e-passport (biometric passport). ESTA does not guarantee entry; final decision is made by CBP officers at the port of entry. Travel must be for business or tourism only; work and study are not permitted under VWP.
Citizens of countries not in the VWP must obtain a visa before travel. This includes most countries in Africa, Asia, South America, and Eastern Europe.
Cost: USD $185 application fee (non-refundable even if denied)
Major countries requiring visas include China, India, Russia, Brazil, South Africa, Vietnam, Thailand, Indonesia, Philippines, Mexico, and most African and Middle Eastern nations. Start the application process at least 2-3 months before intended travel. Visa does not guarantee entry.
Special exemptions apply for Canadian and Bermudian citizens
Canadian citizens generally do not need a visa or ESTA for tourist or business visits and can enter with a valid passport or enhanced driver's license. Bermudian citizens can enter visa-free with a valid passport. However, if arriving by air, Canadians should carry a passport as other ID may not be accepted by airlines.
No visa requirements for U.S. nationals
U.S. citizens need a valid U.S. passport or passport card. Permanent residents (green card holders) must present their valid Permanent Resident Card (Form I-551).
Arrival Process
Upon arrival at a U.S. port of entry (airport), all international travelers must clear immigration and customs. The process is standardized across all U.S. entry points. Many major airports now use Automated Passport Control (APC) kiosks or Mobile Passport Control apps to expedite the process.

Customs & Duty-Free
U.S. Customs and Border Protection regulates what can be brought into the United States. All travelers must complete a customs declaration form and may be subject to baggage inspection. Duty-free allowances are generous for personal use items, but agricultural products, counterfeit goods, and certain other items are strictly prohibited.
Prohibited Items
- Fresh fruits, vegetables, and plants - Risk of introducing pests and diseases (some exceptions with permits)
- Meat, poultry, and animal products - Including fresh, dried, or canned meat products from most countries (severe restrictions due to disease risk)

Health Requirements
The United States has minimal vaccination requirements for entry, but travelers should ensure routine vaccinations are current. Health insurance is strongly recommended as medical care in the U.S. is expensive and not free for visitors.
Required Vaccinations
- COVID-19 vaccination may be required for certain visa categories (check current CDC requirements as policies change)
- Specific vaccinations may be required for immigrants and certain long-term visa holders (measles, mumps, rubella, polio, tetanus, diphtheria, pertussis, Haemophilus influenzae type B, hepatitis A, hepatitis B, rotavirus, meningococcal disease, varicella, pneumococcal disease, and influenza)
Recommended Vaccinations
- COVID-19 - Stay up to date with vaccines and boosters
- Routine vaccinations - Measles-mumps-rubella (MMR), diphtheria-tetanus-pertussis, varicella (chickenpox), polio, and yearly flu shot
- Hepatitis A and B - Recommended for most travelers
- Rabies - Only if planning activities with wildlife exposure
Health Insurance
Travel health insurance is strongly recommended for all visitors to the United States. Medical care is very expensive and visitors are not covered by U.S. health programs. A single emergency room visit can cost thousands of dollars. Ensure your policy covers medical evacuation and repatriation. Minimum coverage of USD $100,000 is recommended. Some visa types may require proof of health insurance.
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, including infants, must have their own passport and visa/ESTA if required by nationality. Children under 18 traveling alone, with one parent, or with non-parents should carry a notarized letter of consent from the non-traveling parent(s) or legal guardian(s). CBP may ask questions to verify the child's relationship to accompanying adults to prevent child abduction. Carry birth certificates showing parents' names. Unaccompanied minors require special airline arrangements and documentation.
Dogs and cats can enter the U.S. with proper documentation. Dogs must have a valid rabies vaccination certificate (administered at least 30 days before entry and valid for duration of stay). Puppies under 12 weeks and from rabies-free countries have different requirements. Starting August 2024, all dogs require a CDC Dog Import Form and must enter at an approved port. Cats do not require rabies vaccination for entry but may need health certificates for airline travel. Service animals have specific documentation requirements. Birds, reptiles, and other animals have additional requirements and restrictions. Contact CDC and USDA/APHIS well in advance.
Tourist visas and ESTA/VWP do not permit extensions for VWP travelers (strict 90-day limit). B-1/B-2 visa holders may apply to extend their stay through USCIS Form I-539 before their authorized stay expires (apply at least 45 days before expiration). Extensions are not guaranteed. Working or studying on a tourist visa/ESTA is illegal. For longer stays, work, or study, you must apply for the appropriate visa type (F-1 for students, H-1B for workers, etc.) from outside the U.S. Overstaying your visa can result in bans from future U.S. entry ranging from 3 years to permanent.
Business visitors on B-1 visa or VWP/ESTA can attend meetings, conferences, negotiate contracts, and conduct consultations, but cannot perform productive work or receive payment from a U.S. source. Carry invitation letters from U.S. company, conference registration, and evidence of business ties to home country. If conducting business activities beyond permissible scope, you may need a work visa (H-1B, L-1, E-2, etc.). Journalists and media require I visa, not tourist visa.
Certain criminal convictions, immigration violations, or previous visa denials can make you inadmissible to the U.S. This includes drug offenses, crimes of moral turpitude, multiple criminal convictions, prostitution, human trafficking, and terrorism-related activities. Previous overstays, deportations, or visa fraud result in entry bars. You may need to apply for a waiver of inadmissibility. Be honest on visa applications and with CBP officers - lying about criminal history or previous violations can result in permanent ban. Consult an immigration attorney if you have concerns about admissibility.
Even if just transiting through a U.S. airport to another country, you must clear U.S. immigration and customs (unlike many countries with transit zones). You need a valid visa or ESTA depending on nationality. Allow sufficient connection time for immigration and customs clearance (minimum 2-3 hours recommended for international connections). You'll collect checked bags, clear customs, and re-check bags for your onward flight.
