Visa Requirements
Entry permissions vary by nationality. Find your category below.
The United States maintains a tiered visa system. Your nationality, purpose of visit, and intended length of stay all determine which category applies to you. The official U.S. immigration website should be your primary reference. Eligibility rules and permitted stays vary by country and are subject to change.
Certain nationalities may enter the United States without a traditional visa, though electronic pre-authorization is typically still required. Eligibility and permitted length of stay depend on your nationality and the specific bilateral agreements in place.
Even where visa-free entry is available, travelers generally still need to obtain an approved electronic travel authorization before departure. A valid passport is always required. Immigration officers retain discretion over admission at the port of entry.
The United States operates the Electronic System for Travel Authorization, known as ESTA, for nationals of Visa Waiver Program countries. ESTA is required for travel to the U.S. by air, sea, or land without a visa.
Cost: A processing fee applies per approved authorization. Check the official ESTA website for the current amount.
An approved ESTA does not guarantee entry. It authorizes you to board a carrier bound for the United States. The final admission decision rests with the Customs and Border Protection officer at the port of entry. Travelers who do not qualify under the Visa Waiver Program will need to apply for a visa instead.
Travelers whose nationality does not qualify for the Visa Waiver Program or ESTA will need to apply for an U.S. visa through an embassy or consulate before traveling to Hartford.
Several visa categories exist depending on the purpose of your visit, including tourist, business, and transit. Your consulate will advise on which type to apply for. As with ESTA, holding a valid visa does not guarantee admission. That decision is made at the port of entry.
Arrival Process
Most international travelers heading to Hartford arrive through Bradley International Airport, located just north of the city in Windsor Locks. The arrival process follows the standard U.S. Customs and Border Protection procedure. This is consistent across all American ports of entry.
Documents to Have Ready
Tips for Smooth Entry
Customs & Duty-Free
U.S. Customs and Border Protection enforces federal regulations on what you can bring into the country. The rules apply uniformly whether you are arriving in Hartford or any other U.S. city. Declaring items honestly avoids fines and delays. Undeclared prohibited items can result in confiscation and penalties.
Prohibited Items
- Most fresh fruits, vegetables, and plant materials, due to the risk of introducing agricultural pests and diseases
- Most meat, poultry, and pork products from foreign countries, for food safety and disease prevention reasons
- Controlled substances and narcotics not accompanied by a valid prescription
- Counterfeit goods, including fake designer items and pirated media
- Fireworks and most explosive materials
- Hazardous materials that do not meet U.S. safety standards
- Items made from endangered species, including ivory, certain skins, and products derived from protected wildlife
Restricted Items
- Prescription medications should be in their original labeled containers, with documentation from your physician if quantities are large or the medication is a controlled substance
- Firearms and ammunition require advance declaration and compliance with both federal and Connecticut state firearms laws
- Certain food products, including some cheeses, cured meats, and bakery items, may be admissible with proper inspection but should be declared
- Cultural artifacts and antiques may require export permits from the country of origin
Health Requirements
The United States does not impose extensive health documentation requirements on most arriving travelers. But there are a few things worth knowing before you head to Hartford.
Required Vaccinations
- There are generally no mandatory vaccinations for short-term visitors entering the United States as tourists. However, travelers arriving from countries where yellow fever is endemic may need to present a valid yellow fever vaccination certificate. Check the official U.S. health authority guidance for the current list of affected countries.
Recommended Vaccinations
- Routine vaccinations should be up to date, including measles-mumps-rubella, diphtheria-tetanus-pertussis, and seasonal influenza
- Hepatitis An and B vaccinations are commonly recommended for international travelers regardless of destination
- Your doctor or a travel health clinic can advise on any additional vaccinations based on your specific itinerary and health history
Health Insurance
The United States does not require tourists to hold health insurance as a condition of entry. But it is strongly advisable. Medical care in the U.S. tends to be expensive, and without insurance, even a minor emergency room visit can result in a substantial bill. Travel insurance that includes medical coverage and emergency evacuation is worth arranging before your trip to Hartford.
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 need their own passport. They also need their own ESTA or visa if applicable. If a child travels with only one parent or with someone who is not their parent, carry a notarized letter of consent from the absent parent or parents. U.S. immigration does not always ask for this. Not having it can cause delays or complications. This happens on the return leg through other countries. Carry custody documents if relevant. Better safe than sorry.
Dogs entering the United States generally need to meet CDC requirements. This may include proof of rabies vaccination. A health certificate from a licensed veterinarian is also often required. Requirements vary depending on the country of origin. They can change. Check the CDC and USDA APHIS websites before traveling. Cats have fewer federal requirements. They should still have up-to-date vaccinations. Airlines have their own pet travel policies. Their fees apply on top of government requirements. Connecticut may have additional state-level regulations for certain animals. Do your homework.
If you want to stay in the United States longer than your initial admission allows, you may apply for an extension through U.S. Citizenship and Immigration Services. Do this before your authorized stay expires. Overstaying your visa or Visa Waiver Program admission carries serious consequences. This includes bars on future entry. For longer-term plans such as work, study, or relocation, specific visa categories exist. You will likely need to apply from outside the United States through a consulate. Plan well in advance.
The United States does not have a true transit visa. This differs from many countries. You cannot pass through without clearing immigration. Even if Hartford or another U.S. city is just a connection point, you will clear immigration and customs. You need either an approved ESTA or a valid visa. Plan accordingly. This process takes time. Your bags will need to be recollected and rechecked. Build in extra hours.
