Oklahoma City Entry Requirements
Visa, immigration, and customs information
Visa Requirements
Entry permissions vary by nationality. Find your category below.
Visa requirements for visiting Oklahoma City are set by the US federal government and apply uniformly nationwide. The United States Visa Waiver Program covers 42 countries whose citizens may visit for up to 90 days without a traditional visa, provided they obtain an approved ESTA before boarding. Citizens of all other countries (with the notable exception of Canada and Bermuda) must obtain a B-2 tourist visa from a US embassy or consulate prior to travel.
Citizens of Canada and Bermuda may enter the United States as visitors without a visa and without ESTA pre-authorization. This is a distinct exemption separate from the Visa Waiver Program.
Canadian citizens traveling by air must carry a valid Canadian passport. At land borders, Canadians may use a passport, NEXUS card, Enhanced Driver's License, or Trusted Traveler document. Bermudian air travelers need a valid Bermudian passport. The CBP officer makes the final determination on length of stay at the port of entry.
Citizens of the 42 VWP member countries may visit the United States for tourism or business for up to 90 days without obtaining a full visa, but must receive ESTA approval before boarding any aircraft or vessel bound for the US. ESTA must be applied for at esta.cbp.dhs.gov — no third-party applications are official.
Cost: USD $21 (as of 2026) — charged to a credit or debit card during the online application. Be aware of fraudulent third-party websites charging higher fees; only esta.cbp.dhs.gov is official.
VWP travelers who have previously been denied a US visa, arrested, or who have traveled to Cuba, Iran, Iraq, Libya, North Korea, Somalia, Sudan, Syria, or Yemen on or after March 1, 2011 are generally ineligible for ESTA and must apply for a B-2 visa instead. Having a criminal record — even a minor one — may also make you ineligible. When in doubt, apply for a visa at a US consulate rather than risk being turned away at the airport.
Citizens of all countries not covered by the VWP must apply for and receive a B-2 (tourist/visitor) visa before traveling to the United States. This includes citizens of China, India, Brazil, Mexico, Russia, the Philippines, Nigeria, Pakistan, and most of the rest of the world. The B-2 visa is obtained at the nearest US embassy or consulate in your home country.
A B-2 visa does not guarantee entry — CBP at the port of entry makes the final admission decision. Visa holders should be prepared to demonstrate the purpose of their visit, sufficient funds, and ties to their home country demonstrating intent to return. Overstaying a visa has serious long-term consequences including multi-year or permanent bars on future US entry.
Arrival Process
Most international visitors traveling to Oklahoma City arrive by air, typically connecting through a major hub such as Dallas/Fort Worth (DFW), Houston Bush Intercontinental (IAH), Denver (DEN), or Chicago O'Hare (ORD). A critical detail: you clear US immigration and customs at your first US port of entry — not in Oklahoma City. By the time your connecting flight lands at Will Rogers World Airport (OKC), you have already been processed by CBP. If you are flying directly from another country into OKC (rare, as OKC has no international routes), you would clear at OKC. Plan your connection times accordingly — US immigration can take 45 minutes to 2 hours at busy hubs.

Tips for Smooth Entry
Customs & Duty-Free
US Customs regulations apply uniformly at all ports of entry. Customs is handled by US Customs and Border Protection (CBP) and is governed by federal law — Oklahoma state law plays no role in what you may bring into the country. Penalties for undeclared items, currency and controlled substances, are severe and can result in confiscation, fines, and future entry bans. When in doubt, declare everything — declaring an item does not automatically mean it will be confiscated or taxed; it simply starts a conversation with a customs officer.
Prohibited Items
- Narcotics and controlled substances (marijuana is federally illegal in the US regardless of state law — it cannot be brought across the US border)
- Counterfeit currency, goods, or documents — any item bearing a fraudulently applied trademark
- Firearms and ammunition without proper ATF import permits and prior authorization (tourist firearm importation is strictly controlled)
- Obscene materials including child exploitation material
- Products made from endangered species protected under CITES (coral, certain reptile skins, ivory, certain feathers) without CITES permits
- Switchblade knives with blades over 3 inches imported from abroad
- Merchandise from comprehensively sanctioned countries (certain Cuban goods, most North Korean goods, certain Iranian goods) above personal exemption limits
- Most fresh fruits, vegetables, and unprocessed meats without USDA permits — this includes produce purchased in-flight or leftover from airplane meals
Restricted Items
- Firearms and ammunition — importation by non-US citizens is legal but requires ATF Form 6 approval obtained before travel; sport shooters and hunters have specific exemption pathways
- Prescription medications — bring only personal-use quantities (typically a 90-day supply or less), keep medications in original labeled containers, carry a copy of your prescription or a letter from your doctor, and be aware that some medications legal in your home country may be controlled or illegal in the US
- Certain agricultural products (plants with soil, seeds, live insects, unprocessed animal products) — contact USDA APHIS before travel if you are bringing plant material or biological specimens
- Large quantities of Cuban cigars — up to 100 for personal use is permitted following recent rule changes, but commercial quantities remain prohibited
- Soil — any amount of soil attached to shoes, camping gear, or plant roots must be declared; US agriculture inspectors take soil biosecurity very seriously
Health Requirements
The United States currently has no mandatory health-related entry requirements for international tourists beyond standard immigration documentation. COVID-19 vaccination requirements for inbound international travelers were permanently lifted by the US government in May 2023 and have not been reinstated. However, health conditions evolve, and travelers should check current requirements with the CDC and US State Department before departure.
Required Vaccinations
- Yellow fever vaccination certificate — required only if you are arriving directly from a country with risk of yellow fever transmission as designated by the WHO, or if you have transited through such a country within 12 days. This is enforced by CBP and CDC under the Quarantine Station regulations. For most travelers to Oklahoma City arriving via standard international routes, this does not apply.
Recommended Vaccinations
- Routine US childhood vaccines: measles-mumps-rubella (MMR), diphtheria-tetanus-pertussis (Tdap), varicella (chickenpox), polio
- Hepatitis A and Hepatitis B — recommended for all international travelers as a precaution
- Seasonal influenza vaccine — relevant October through March
- COVID-19 — no longer required for entry but still widely recommended by the CDC for international travelers
- Meningococcal vaccine — recommended for travelers who will be in close contact with large groups or in dormitory-style accommodation
Health Insurance
The United States does not have universal public health care. Medical treatment in the US is extraordinarily expensive by international standards — a single emergency room visit can cost USD $1,000–$10,000 or more, and a hospital admission can easily exceed USD $50,000. Travel health insurance with complete medical coverage is very strongly recommended for all international visitors. Ensure your policy covers emergency medical treatment, hospitalization, and medical evacuation. Without insurance, you are personally liable for all medical costs.

Special Situations
Additional requirements for specific circumstances.
US citizens and permanent residents traveling with minors need no special documentation beyond the child's own valid US passport (or green card). For international travelers: each child must have their own valid passport and ESTA or visa. If a child is traveling with only one parent, or with grandparents, other relatives, or a school group, CBP strongly recommends carrying a notarized letter of consent from the absent parent(s) or legal guardian, authorizing the travel. While not legally required for US entry, this letter can prevent significant delays and difficulties at immigration, if the child has a different surname than the accompanying adult. Single parents, divorced parents, and non-biological guardians should always carry custody documentation and consent letters.
Dogs entering the United States must be healthy and free of signs of disease communicable to humans. As of August 2024, dogs that have been in or transited through any country classified as high-risk for dog rabies by the CDC must comply with updated CDC requirements, which may include proof of CDC-compliant rabies vaccination or a serological titer test. Cats generally have fewer restrictions. All pets must have a health certificate from a licensed veterinarian issued within 10 days of travel. Service animals have specific documentation requirements. For the most current and complete pet import requirements, consult the CDC (cdc.gov/importation/dogs) and USDA APHIS (aphis.usda.gov) well before your travel date — requirements have changed significantly in recent years.
VWP travelers cannot extend or change status — the 90-day limit is absolute, and overstaying results in automatic bars on future US entry (3-year bar for overstays up to one year, 10-year bar for longer overstays). B-2 visa holders may apply for an extension of stay using Form I-539 filed with USCIS before their current authorized period expires. Extensions are not guaranteed and can take several months to process. Filing a timely I-539 maintains your lawful status while the application is pending. Working without authorization is illegal regardless of visa category. If you need to stay in the US for more than 6 months, consult an immigration attorney about the appropriate visa category for your circumstances.
Dual citizens who hold US citizenship must enter and exit the United States on their US passport — using a foreign passport to enter the US as a US citizen is a violation of US law. Dual citizens who are not US citizens but hold citizenship in a VWP country and another country should check whether travel history or citizenship from non-VWP countries affects their ESTA eligibility. In some cases, dual nationals are required to apply for a B-2 visa even if one of their nationalities would otherwise qualify for VWP.
If you have ever been denied a US visa, denied entry at a US port of entry, deported, or overstayed a previous visit, you are generally ineligible for the Visa Waiver Program regardless of your nationality. You must apply for a B-2 visa and disclose the previous denial or issue during your interview. Attempting to enter via ESTA when you are ineligible — or failing to disclose a previous refusal on your ESTA application — is a federal offense and will result in denial of entry. Consult an immigration attorney before attempting to re-enter the US if you have any prior immigration issues.
Travelers visiting Oklahoma City specifically for medical treatment (such as visiting OU Health or Oklahoma Heart Hospital) should apply for a B-2 visa noting medical treatment as the purpose of their visit, or ensure their B-2 visa covers medical visits. Bring full documentation of your medical appointments, the treating institution's details, and evidence that you have sufficient funds to cover treatment and living costs. Medical tourism in the US is legal under B-2 status but requires clear documentation and advance planning.
