Chico sits in Northern California's Sacramento Valley. Reaching it as an international traveler means clearing United States entry requirements first. Most visitors fly into Sacramento International Airport, San Francisco International, or another major US gateway. They then head north to Chico by road or regional connection. The entry process stays the same regardless of which US port you choose. The formalities covered here apply whether you land on the West Coast or anywhere else in the country. The United States uses a tiered entry system. Some nationalities qualify for the Visa Waiver Program. This allows travel without a traditional visa. It does require an approved Electronic System for Travel Authorization, known as ESTA, before departure. Other travelers need a visa obtained through a US embassy or consulate. Eligibility and permitted length of stay depend on your nationality. Checking the official US immigration website before booking is worth the few minutes it takes. Requirements do shift, sometimes with little notice. Entry rules, fee structures, and documentation expectations can change between booking and boarding. Treat everything here as a reliable starting framework. Confirm the details that matter most through official US government sources before your trip to Chico.

Visa Requirements

Entry permissions vary by nationality. Find your category below.

The United States determines entry eligibility by nationality. Travelers fall into one of three broad categories. Which category applies to you dictates whether you need a visa, an ESTA, or something else entirely. The official US immigration website is the definitive source for which category your nationality falls into. Check it even if you have traveled to the US before. Bilateral agreements do change.

Visa-Free Entry
The permitted length of stay depends on your nationality and the terms of the Visa Waiver Program. Check the official US immigration website for the current allowance that applies to your passport.

Nationals of countries participating in the Visa Waiver Program may enter the United States without obtaining a traditional visa. They must hold an approved ESTA before travel. This is not quite the same as unrestricted visa-free entry. The ESTA application can be denied. For most eligible travelers the process is straightforward.

Even under the Visa Waiver Program, entry is never guaranteed. The immigration officer at your US port of arrival makes the final decision. You will need a valid machine-readable passport. Bring your approved ESTA. Carry evidence of onward or return travel.

Electronic Travel Authorization (ETA/eVisa)
An approved ESTA is typically valid for multiple trips over a two-year period or until your passport expires, whichever comes first. The permitted stay per visit depends on your nationality and the terms of the program.

ESTA, the Electronic System for Travel Authorization, is the pre-travel screening required for Visa Waiver Program nationals visiting the United States by air, sea, or land. It is not a visa. It is an authorization to board a carrier bound for the US without one.

How to Apply: Apply through the official ESTA website operated by US Customs and Border Protection before your trip. Processing is often quick. Sometimes it takes minutes. It can take up to 72 hours. Apply well in advance. Do not wait until the last minute. Use only the official government site. Third-party services charge additional fees for the same application.
Cost: USD 40.27 per approved authorization (fiscal year 2026). The fee applies regardless of the outcome if the application is denied at a later stage.

ESTA approval does not guarantee entry to the United States. It authorizes you to travel to a US port of entry. A CBP officer makes the final admission decision there. If your ESTA is denied, you will need to apply for a visa through a US embassy or consulate instead.

Visa Required
The permitted length of stay is determined by the CBP officer at your port of entry and stamped in your passport. It varies by visa type and individual circumstances.

Travelers whose nationality does not qualify for the Visa Waiver Program must obtain a visa from a US embassy or consulate before traveling. The most common type for tourism is the B-1/B-2 visitor visa. The appropriate category depends on the purpose of your visit.

How to Apply: Apply at the US embassy or consulate in your country of residence. The process typically involves completing an online application. You will pay a processing fee. You will attend an in-person interview. Processing times vary considerably by location and season. Apply well ahead of your planned travel dates.

A valid visa does not guarantee entry. The final admission decision rests with the CBP officer at the port of entry. Be prepared to show supporting documentation. Bring proof of accommodation. Show financial means. Have return or onward travel plans ready.

Arrival Process

If you are arriving internationally, you will clear US immigration and customs at your first US airport. You will not clear in Chico itself. Most travelers heading to Chico connect through Sacramento, San Francisco, or Los Angeles. The entry process is the same at every US port of arrival. Several steps stand between landing and walking out of the terminal.

1
Immigration Inspection
After leaving the aircraft, follow signs to the immigration hall. You will join the line for non-US citizens. Present your passport. Show your approved ESTA confirmation or visa. Hand over a completed customs declaration form if one was not handled electronically. The officer may ask about the purpose and duration of your visit. Many airports now use Automated Passport Control kiosks for eligible travelers. This can speed up the step considerably.
2
Biometrics Collection
Most non-US citizens are photographed and digitally fingerprinted as part of the inspection. This is standard procedure. It usually takes less than a minute.
3
Baggage Claim
Clear immigration first. Then grab your checked bags from the carousel. Connecting domestically to Chico or Sacramento? You will usually need to collect your luggage, clear customs, and re-check it for the next leg. Plan for this.
4
Customs and Agriculture Inspection
Hand your customs declaration to the CBP officer. Declare any food, plants, or agricultural products you are carrying. The US enforces strict agricultural import rules. California adds its own restrictions on certain produce and plant material. Random bag inspections happen often. They are routine. Declare everything honestly and you will be fine.
5
Exit and Onward Travel
Once customs clears you, head to ground transportation, your connecting flight, or the arrivals hall. Driving north from Sacramento to Chico takes about an hour and a half in normal traffic. Budget more during rush hour.

Documents to Have Ready

Valid Passport
Your passport must be machine-readable. It must stay valid for your entire intended stay. Some nationalities need six months validity beyond entry. Check the official US immigration website to see if this applies to you.
Approved ESTA
ESTA is required for Visa Waiver Program nationals before any travel by air, sea, or land. Apply through the official ESTA website run by US Customs and Border Protection. The current fee is USD 40.27 per approved authorization. Bring a printed or digital copy of your approval.
Valid US Visa
A visa is required if your nationality does not qualify for the Visa Waiver Program. It must be valid. It must match the purpose of your visit.
Proof of Onward or Return Travel
Immigration officers may request proof of return or onward travel out of the United States. Keep this handy. Printed or on your phone works. It speeds up the inspection.
Customs Declaration
The customs declaration states what you are bringing into the country. Many airports now offer electronic completion before landing. Paper forms remain available on the aircraft if you prefer.

Tips for Smooth Entry

Organize your documents before you reach the immigration officer. Keep your passport, ESTA confirmation or visa, and proof of accommodation and return travel together. This saves time. It also helps your case.
Answer immigration questions directly and honestly. Officers repeat the same questions thousands of times daily. Brief, clear answers work better than long explanations. Keep it simple.
Connecting through a major hub like San Francisco or Los Angeles? Allow plenty of time between your international arrival and domestic connection. Immigration and customs processing varies widely. Missing a connection to Sacramento or Chico could strand you overnight. Plan accordingly.
California enforces stricter agricultural inspection rules than federal requirements alone. Declare all food, seeds, and plant material you carry. Undeclared items trigger fines and confiscation. Agricultural inspectors at California entry points take this seriously. The state's farming economy depends on it. This matters in Chico and the Sacramento Valley as much as anywhere.

Customs & Duty-Free

US Customs and Border Protection sets federal rules on what you can bring into the country. California layers its own agricultural restrictions on top. Chico sits in central California's agricultural Sacramento Valley. Knowing both rule sets matters here. Duty-free allowances cover items for personal use. Anything beyond the limits requires declaration.

Alcohol
You may bring a limited quantity of alcoholic beverages for personal use. The typical allowance is around one liter per adult traveler. This varies by entry state and your residency status. Check specifics.
You must be at least 21 years old to bring alcohol into the United States. Quantities above the duty-free threshold incur duty and federal tax. Declare everything.
Tobacco
You may bring a limited quantity of tobacco products for personal use. The standard federal allowance is roughly 200 cigarettes or an equivalent amount of other tobacco products. Know your limits.
You must be at least 21 years old. California maintains its own tobacco regulations. Some products legal elsewhere face restrictions here. Research before you pack.
Currency
There is no cap on currency you may bring into the United States. Amounts at or above the federal reporting threshold must be declared to CBP on arrival. Do not skip this.
The reporting threshold covers cash, traveler's checks, money orders, and certain other monetary instruments combined. Failure to declare amounts above the threshold risks seizure and penalties. Verify the current threshold on the CBP website before you travel.
Gifts/Goods
You may bring personal goods and gifts within the applicable duty-free value limit. This limit differs for returning US residents versus visitors. Know your category.
Items exceeding the duty-free threshold face customs duty. Keep receipts for anything of significant value. This speeds assessment if officers ask.

Health Requirements

Required Vaccinations

  • Arriving from a yellow fever risk region? You may need proof of vaccination. Carry your International Certificate of Vaccination. Keep your yellow card accessible.

Health Insurance

The United States offers no national health service for visitors. Medical care costs far more than many travelers expect. Buy travel health insurance. Cover medical treatment and emergency evacuation. Chico has Enloe Medical Center and urgent care. Complex cases may require transfer to Sacramento, roughly 90 minutes south.

Current Health Requirements: Yellow fever risk country arrivals may need a valid vaccination certificate. Otherwise, the US requires no specific health documents from most origins. Requirements shift. Check the US Centers for Disease Control and Prevention. Verify with your home country's travel health authority before departure.
