Hartford Entry Requirements
Visa, immigration, and customs information
Visa Requirements
Entry permissions vary by nationality. Find your category below.
Citizens of the 42 VWP countries can enter the United States, and so Hartford, for tourism or business for up to 90 days without a visa. Every VWP traveler must have an approved ESTA before getting on a US-bound flight or ship. ESTA is not a visa. It is an automated check that must clear before you travel.
Even if your country is in the VWP, you cannot use the program if you have overstayed a previous visa, hold certain criminal convictions, or have been in Cuba, Iran, Iraq, Libya, North Korea, Somalia, Sudan, Syria, or Yemen on or after March 1, 2011; such travelers must apply for a visa. You must secure ESTA approval before you leave, airport applications are not allowed.
ESTA is the required pre-clearance system for every Visa Waiver Program traveler. It is not a visa but a mandatory authorization that must be granted before you board any US-bound air or sea carrier. CBP runs security checks through ESTA while you are still overseas.
Cost: Fee is USD $21 per application (2026 rate). This covers a $4 system authorization charge and a $17 travel promotion charge.
Answer every ESTA question honestly, false information can make you permanently inadmissible. An approved ESTA does not guarantee entry. The CBP officer at the port of entry has the final say.
Travelers from countries outside the Visa Waiver Program must secure a US nonimmigrant visa before heading to Hartford. The usual types are B-2 (tourism or pleasure) and B-1 (business). You must obtain the visa at a US embassy or consulate in your home country before you depart.
Major nationalities that need a B-2 visa include citizens of China, India, Russia, Mexico, Philippines, Vietnam, Indonesia, Pakistan, Nigeria, Egypt, Saudi Arabia, and most countries in Africa, South Asia, and Central Asia. A previous visa refusal does not automatically block a new application. But you must list every prior refusal on Form DS-160.
Arrival Process
Most people flying into Hartford from abroad land at Bradley International Airport (BDL) in Windsor Locks, about 15 miles north of downtown, or touch down at a larger hub like Boston Logan, JFK, or Newark and ride a bus or Amtrak the rest of the way. Every international arrival goes through US Customs and Border Protection at the first airport in the country, so if you change planes elsewhere in the States, you'll clear customs there, not in Hartford. The steps are the same at every US port of entry.

Customs & Duty-Free
US Customs and Border Protection enforces federal customs law at all ports of entry. Hartford is reached via BDL or overland from another US port of entry, so customs is cleared wherever you first enter the United States. US customs rules are the same across the country and include strict agricultural biosecurity measures, currency reporting requirements, and duty-free import thresholds.
Prohibited Items
- Narcotics and controlled substances (including cannabis, which remains federally illegal in the US even though Connecticut state law allows adult use. Possession at the federal border is a federal crime)
- Firearms and ammunition without prior ATF and CBP authorization (Form 6NIA required)
- Counterfeit goods of any kind, copies of branded merchandise, pirated software, fake currency
- Obscene material, child pornography, or material advocating sedition against the US government
- Cuban cigars in commercial quantities imported directly from Cuba (personal-use quantities now generally allowed)
- Products made from endangered species (CITES-listed wildlife parts, ivory, certain furs, reptile products) without valid permits
- Merchandise from comprehensively sanctioned countries, including most items from North Korea, Cuba (commercial goods), Iran, and Syria
- Soil and certain plants without USDA/APHIS permits
- Lottery tickets and certain gambling paraphernalia
Restricted Items
- Firearms and ammunition, allowed with prior written authorization from ATF; must declare on arrival. Sportsmen and hunters should check cbp.gov well in advance
- Prescription medications, allowed for personal use in reasonable quantities. Carry original prescription and physician letter. Controlled substances need extra documentation
- Certain agricultural products, some fruits, vegetables, plants, seeds, and meats can be imported with appropriate USDA APHIS permits
- Pets and animals, see Special Situations below. Health certificates and vaccinations are required
- Cultural artifacts and antiquities, items over 100 years old, artwork, and archaeological artifacts may need documentation of legal export from country of origin
- Alcohol above 1 liter, allowed but subject to federal duty and state excise tax
- Gold coins and bullion, allowed but amounts over $10,000 must be declared as monetary instruments
Health Requirements
The United States doesn't currently require proof of routine vaccinations for most international travelers entering for tourism or business. However, specific health requirements apply to certain visa categories, long-term stays, and travelers from countries with active disease outbreaks. Travelers should also think about practical health preparations given the high costs of the US healthcare system.
Required Vaccinations
- COVID-19 vaccination stopped being a federal entry requirement for the United States in May 2023 and had not been brought back as of early 2026. Still, double-check cdc.gov right before you leave in case the rule changes.
- If you're applying for an immigrant visa or certain non-immigrant visas such as K or V, you have to show you've had the vaccinations on the CDC list during the required medical exam. Ordinary B-1/B-2 visitors and Visa Waiver travelers don't need those shots.
- Coming from a country where yellow fever is spreading? You might be asked for proof of vaccination, look up the latest CDC travel notice.
Recommended Vaccinations
- Make sure your routine shots are current before you fly: MMR, Tdap, chickenpox, polio, and this year's flu vaccine.
- COVID-19 vaccine isn't mandatory to enter the US, but the CDC still advises it, for older travelers or anyone with a weak immune system.
- Hepatitis An and B shots are recommended for anyone leaving their home country. Hartford's restaurants follow strict food-safety rules. Yet the vaccines give long-term cover.
- Plan to sleep in dorms or crowd into big events? Consider the meningococcal vaccine.
Health Insurance
The US has no free national health service. Without insurance, an ER visit can bill you USD 1,000, 3,000 before any treatment, and a hospital bed runs 5,000, 30,000 dollars a day. Buy travel medical insurance with at least 100,000 USD in cover plus evacuation benefits; Hartford brokers sell policies you can compare. Make sure the plan lists the US and covers any condition you already have, your policy back home almost never pays here.

Special Situations
Additional requirements for specific circumstances.
US Customs doesn't demand a notarized letter when both parents fly with a child. Yet airlines often do if only one parent or a guardian is traveling. Bring a signed, notarized note from the absent parent(s) with contact details and the trip plan. If a parent has died, pack a copy of the death certificate. If you have sole custody, bring the court order. The US follows the Hague Convention, so officers watch for possible abductions.
Dogs must look healthy on arrival. Since August 2024, those coming from CDC-listed high-risk rabies countries need a US microchip and CDC-approved rabies shot. Dogs from low-risk countries can enter without a rabies certificate if they seem healthy but still need a chip. Cats don't need rabies shots but must appear well. All pets can be inspected by CBP and USDA staff, and airlines often add stricter rules, check with your carrier. Hartford follows Connecticut law. The city adds no extra pet rules.
If you enter under the Visa Waiver Program, the 90-day clock cannot be paused or reset, once it runs out, you must leave. B-2 tourists, on the other hand, may file Form I-539 with USCIS before their current permission expires to ask for more time. Approval is discretionary and the petition must be submitted while your status is still valid. Anyone who wants to stay for employment needs a company-sponsored work visa such as H-1B, O-1, or L-1. Those who plan to study must obtain a F-1 student visa before arrival. Overstaying by even one day goes on your permanent record, triggers re-entry bars (three years for 180 days, one year, ten years for more than one year), and can lead to a lifetime finding of inadmissibility.
Medical treatment falls squarely within the B-2 category. If you are traveling to Hartford specifically for care at Hartford Hospital, St. Francis Hospital, or any other facility, bring: a letter from your doctor at home describing the condition and why U.S. care is necessary; a letter from the U.S. physician confirming the appointment and treatment plan. Proof that you can pay every bill. And evidence of a ticket or other plan to leave once treatment ends. Medical visits on the Visa Waiver Program are allowed. But the 90-day limit is fixed. USCIS can grant B-2 extensions for continuing treatment, speak with an immigration lawyer before deadlines approach.
List every arrest, charge, conviction, and past U.S. visa refusal on both the ESTA and the DS-160. Drug offenses, crimes involving moral turpitude, and offenses punished by more than a year in prison can make you permanently inadmissible. A waiver exists (Form I-192 for VWP travelers or a separate waiver processed with a visa application), but it is discretionary and can take six to eighteen months. Never travel with unreported convictions. Lying on immigration forms is itself a permanent bar to entry.
Hartford has true four-season weather, including heavy winter storms from December through March and occasional summer thunderstorms. Bradley International Airport can shut down or delay flights during major snow events. Check weather.gov, confirm your flight status with the airline 24 hours before departure, and buy travel insurance that covers cancellations and interruptions caused by weather. If officials declare a weather emergency while you are in town, follow instructions from Connecticut DEMHS and local alert systems. The city posts updates at hartfordct.gov.
