Sacramento Entry Requirements
Visa, immigration, and customs information
Visa Requirements
Entry permissions vary by nationality. Find your category below.
Entry requirements for the United States depend on the traveler's country of citizenship, the purpose of the visit, and the intended duration of stay. The primary programs are the Visa Waiver Program (VWP) and traditional visa applications.
Citizens of Visa Waiver Program (VWP) countries can travel for tourism or business for up to 90 days without obtaining a visa.
Must have a valid Electronic System for Travel Authorization (ESTA) approval prior to travel. Passport must be an e-Passport (biometric).
The ESTA is a mandatory pre-travel authorization for VWP travelers. It is not a visa.
Cost: $21 USD
ESTA approval is valid for two years or until passport expiry, whichever comes first. It does not guarantee entry. Must be obtained before boarding a flight or ship to the U.S.
Citizens of countries not in the VWP must apply for a nonimmigrant visa (typically B-1/B-2) at a U.S. embassy or consulate before travel.
Processing times vary widely by location and season; apply months in advance. A visa in your passport allows you to travel to a U.S. port of entry and request permission to enter.
Arrival Process
For Sacramento-bound travelers, the entry process occurs at the first U.S. airport you land in (e.g., San Francisco International-SFO, Los Angeles-LAX, or Sacramento International-SMF if arriving via a pre-cleared international flight).

There are currently no nationwide vaccination requirements for general travelers to the United States. However, specific health requirements can change, and recommendations are in place.
Required Vaccinations
- None for general tourism/business travel
Recommended Vaccinations
- Routine vaccinations (MMR, diphtheria-tetanus-pertussis, varicella, polio, flu)

Health Insurance
The U.S. does not require health insurance for entry, but it is HIGHLY RECOMMENDED. Medical care in the U.S. is extremely expensive. Travelers should purchase complete travel health insurance that covers medical treatment, hospitalization, and medical evacuation.

Special Situations
Additional requirements for specific circumstances.
While not always mandatory, carrying a notarized consent letter from non-accompanying parents is strongly recommended to prevent delays, for single parents, grandparents, or guardians. The letter should authorize travel, provide contact details, and include trip details. For infants, a passport is required regardless of age.
Dogs must be vaccinated against rabies at least 30 days before entry (with some exceptions). A valid rabies vaccination certificate is required. Cats are not required to have rabies vaccination for entry but are subject to state regulations. Check CDC and USDA APHIS requirements for the latest rules, which may include breed restrictions and health checks.
If you wish to stay longer than the time granted on your I-94, you must apply for an extension with U.S. Citizenship and Immigration Services (USCIS) using Form I-539 BEFORE your authorized stay expires. Overstaying is a serious violation and can result in deportation and future bans from the U.S. Visa Waiver Program (ESTA) stays cannot be extended.
