Visa Requirements
Entry permissions vary by nationality. Find your category below.
The United States maintains several visa categories. Which one applies to you depends entirely on your nationality and the purpose of your trip. Eligibility, permitted length of stay, and documentation requirements vary by country. Travelers heading to Sacramento should confirm their specific situation with the official U.S. immigration authority before making travel arrangements.
Certain nationalities may enter the United States without obtaining a traditional visa. Most still need electronic pre-authorization through ESTA. Whether you qualify and the conditions of your stay depend on bilateral agreements between the U.S. and your country of citizenship.
Even travelers who do not need a visa will typically need an approved ESTA before departure. A valid passport is required in all cases. Most travelers should ensure their passport remains valid for at least six months beyond their planned stay. Some bilateral agreements may waive this requirement. Confirm the specifics for your nationality with the official immigration authority.
Nationals of Visa Waiver Program countries must obtain an approved ESTA (Electronic System for Travel Authorization) before traveling to the United States by air, sea, or land. ESTA is not a visa. It is an electronic screening that determines whether you are eligible to travel under the Visa Waiver Program.
Cost: Approximately USD 40.27 per approved authorization, subject to periodic adjustment. Apply only through the official ESTA website. Avoid look-alike sites that overcharge.
An approved ESTA does not guarantee entry to the United States. The final decision rests with the CBP officer at the port of entry. They may still ask about the purpose of your visit, your accommodation plans in Sacramento, and your return travel. If your ESTA application is denied, you will need to apply for a visa through an U.S. embassy or consulate.
Travelers whose nationalities are not covered by the Visa Waiver Program need to apply for an U.S. visa before traveling to Sacramento. The most common category for tourism and short business visits is the B-1/B-2 visitor visa.
A valid visa does not guarantee entry to the United States. As with all arrivals, the CBP officer at the port of entry makes the final determination. Bring supporting documentation. Proof of onward travel, Sacramento hotel reservations, and evidence of financial means tend to make the process smoother.
Arrival Process
If Sacramento International Airport is your first point of entry into the United States, you will clear immigration and customs there. More often, international travelers connect through a larger gateway such as San Francisco, Los Angeles, or Dallas. They complete the entry process before catching a domestic flight to Sacramento. Either way, the procedure is the same.
Documents to Have Ready
Tips for Smooth Entry
Customs & Duty-Free
U.S. Customs and Border Protection enforces detailed rules on what travelers may bring into the country. You will go through customs at whichever U.S. airport you first enter. This could be Sacramento or a connecting hub. The general principle is straightforward: when in doubt about whether to declare something, declare it. There is no penalty for declaring an item that turns out to be fine. There can be significant consequences for failing to declare something that should have been reported.
Prohibited Items
- Most fresh fruits, vegetables, and plants are restricted. This is due to the risk of introducing agricultural pests and disease.
- Most meat, poultry, and pork products from other countries
- Illegal narcotics and certain controlled substances
- Cuban cigars and most goods of Cuban origin
- Counterfeit branded goods and pirated materials
- Products derived from endangered species are prohibited. This includes ivory, certain animal skins, and coral.
- Absinthe containing thujone above the permitted concentration
Restricted Items
- Prescription medications should be in their original labeled containers with a valid prescription. Controlled substances may require additional documentation from your physician.
- Firearms and ammunition require proper federal and state permits. They must be declared at entry.
- Certain prepared food items may be admissible with proper labeling. This includes some aged cheeses, cured meats, and commercially packaged goods. They are subject to inspection.
- Soil, sand, and unprocessed plant material are generally restricted. This is due to agricultural quarantine concerns.
Health Requirements
The United States does not impose an extensive list of mandatory health requirements for most visitors. There are a few important considerations for travelers heading to Sacramento.
Required Vaccinations
- You may need a yellow fever vaccination certificate if you are arriving from, or have recently transited through, a country where yellow fever is endemic. The CDC maintains the list of affected countries. Check the current version before you travel.
Recommended Vaccinations
- Keep your routine vaccinations current. This includes measles-mumps-rubella (MMR), diphtheria-tetanus-pertussis, polio, and seasonal influenza.
- Hepatitis An and Hepatitis B vaccinations are commonly recommended for international travelers who may not already be immunized.
- Consult your healthcare provider. They can give personalized recommendations based on your health history and travel plans.
Health Insurance
The United States does not require proof of health insurance for entry. Medical treatment in Sacramento and across the U.S. can be expensive, even for minor issues. Travel health insurance that explicitly covers the United States, including emergency medical treatment and evacuation, is strongly advisable. Verify that your policy does not exclude the U.S., as some global travel policies do. If you take regular medication, bring enough for your trip plus a buffer, along with a copy of your prescription.
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.
Every child, including infants, needs their own valid passport and, if applicable, their own ESTA approval or visa to enter the United States. If a child is traveling with only one parent, or with an adult who is not their parent, carrying a notarized letter of consent from the absent parent or legal guardian is strongly advisable. CBP does not always ask for this documentation. When they do, not having it can cause substantial delays or even denial of entry. If custody arrangements or adoption are relevant, bring certified copies of those documents as well.
Dogs entering the United States must meet requirements set by both the CDC and the USDA, which may include proof of current rabies vaccination and a health certificate issued by a licensed veterinarian within a specific window before travel. These requirements have tightened in recent years, and they vary by the animal's country of origin. Cats face fewer federal requirements but should still travel with health documentation. Check with the CDC and USDA for the most current rules well before your trip, as some requirements involve lead times that cannot be rushed. Airlines also impose their own pet travel policies, which may differ from federal requirements.
If you wish to remain in Sacramento or elsewhere in the United States beyond the period authorized at your port of entry, you will likely need to apply for an extension of stay through U.S. Citizenship and Immigration Services before your authorized period expires. Overstaying your authorized stay, even by a single day, can have serious consequences, including difficulty obtaining future visas and potential entry bans. For longer-term purposes such as employment or academic study, a specific visa category is required. Consult the official USCIS website for extension procedures, processing times, and eligibility criteria.
