Visa Requirements
Entry permissions vary by nationality. Find your category below.
The United States runs a tiered entry system. You might enter visa-free under the Visa Waiver Program, need electronic travel authorization, or require a full visa. It depends on your nationality. Eligibility and permitted length of stay vary. Check the official US immigration website for your passport's rules.
Nationals of Visa Waiver Program countries enter without a traditional visa. They still need an approved Electronic System for Travel Authorization before traveling. Whether you qualify, and for how long, depends on bilateral agreements between the United States and your home country.
Even visa-free travelers need a valid passport and approved ESTA. Officers may ask for proof of onward travel and sufficient funds. Entry is never guaranteed. The border officer at your port of arrival decides.
ESTA stands for Electronic System for Travel Authorization. It is required for Visa Waiver Program nationals entering by air, sea, or land. It is not a visa. It authorizes you to board a US-bound carrier and present yourself for admission at the border.
Cost: About USD 40.27 per approved authorization. Fees change. Check esta.cbp.dhs.gov before applying.
ESTA approval does not guarantee entry. Border officers decide on arrival. If denied, you usually need a visa from a US embassy or consulate.
Travelers outside the Visa Waiver Program need a visa before arrival. Apply through a US embassy or consulate. Expect an in-person interview.
Common visitor visas cover tourism and business. Interview wait times stretch at busy consulates, in peak season. The US Department of State website lists current waits by embassy.
Arrival Process
You clear immigration and customs at your first US port of entry. Most Stockton visitors process at San Francisco International, Sacramento International, or another California gateway. Keep documents ready. The process is straightforward.
Documents to Have Ready
Tips for Smooth Entry
Customs & Duty-Free
US Customs and Border Protection enforces strict rules on what you can and cannot bring into the country. These regulations apply equally whether you are arriving at a major international hub or a smaller port of entry on your way to Stockton. Declare anything you are uncertain about. Penalties for undeclared restricted items tend to be considerably harsher than for items you voluntarily disclosed. Read signs. Follow rules. Stay compliant.
Prohibited Items
- Most fresh fruits, vegetables, plant material face limits due to agricultural pest and disease prevention concerns. Check.
- Most meat and meat products from outside the US face bans, from countries with active animal disease situations. Check.
- Illegal narcotics and controlled substances without a valid US prescription
- Counterfeit goods, including knockoff branded merchandise
- Products derived from endangered species, such as ivory, certain skins, and some traditional medicines containing protected animal or plant ingredients face strict bans. Check.
- Switchblade knives and certain other weapons prohibited under federal law
Restricted Items
- Prescription medications should be in their original labeled containers with a copy of the prescription or a doctor's letter. Quantities should be consistent with personal use during your trip. Pack neatly. Keep records. Travel light.
- Firearms and ammunition require advance permits, must be declared at entry, and are subject to strict federal and California state regulations. Verify rules.
- Certain processed food items such as hard cheeses, baked goods, and commercially sealed products may be permissible but should be declared for inspection. Pack carefully. Check borders.
- Cultural artifacts, antiquities, and items of archaeological significance may require export permits from the country of origin. They could be subject to seizure if documentation is incomplete. Verify papers. Pack smart. Travel clean.
Health Requirements
The United States does not impose extensive health documentation requirements on most arriving travelers. But there are situations where proof of vaccination or health screening may apply. Healthcare in the Stockton area and throughout the US operates largely on a private insurance model, so preparing on the health front before you travel is worth the effort.
Required Vaccinations
- No vaccinations are broadly required for short-term visitor entry. However, travelers arriving from countries where yellow fever is endemic may need to present a valid yellow fever vaccination certificate. The US Centers for Disease Control and Prevention maintains the current list of affected countries.
Recommended Vaccinations
- Routine vaccinations such as measles-mumps-rubella, tetanus-diphtheria, and seasonal influenza should ideally be up to date before international travel
- Hepatitis An and Hepatitis B vaccinations are commonly recommended for international travelers to the US
- Consult your home country's travel health advisory for any additional recommendations based on your medical history and itinerary
Health Insurance
The United States has no public healthcare safety net for visitors, and medical treatment, even for relatively minor issues, can be extremely expensive. Complete travel health insurance covering emergency medical treatment, hospitalization, and medical evacuation is strongly advisable for any visit to Stockton or elsewhere in the US. Verify that your policy explicitly covers the United States, as some travel insurance plans exclude or limit US coverage due to high healthcare costs in the country.
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, including infants, need their own passport and, if applicable, their own ESTA or visa. If a child is traveling with only one parent or with someone other than their parents, carrying a notarized letter of consent from the absent parent or legal guardian is strongly advisable. While not always requested, border officers may ask for this documentation, and having it ready avoids potential delays or complications at immigration. Custody documents, if relevant, are also worth keeping accessible.
Bringing a pet into the United States involves meeting requirements set by federal agencies and, in some cases, the state of California. Dogs generally need a valid health certificate from a licensed veterinarian and current rabies vaccination documentation. California may impose additional requirements for certain species. Contact the US Department of Agriculture's Animal and Plant Health Inspection Service and the California Department of Food and Agriculture well ahead of travel to confirm the current rules for your specific animal.
If you wish to stay in Stockton or elsewhere in the United States beyond the period authorized at entry, you typically need to apply for an extension through US Citizenship and Immigration Services before your authorized stay expires. Overstaying can result in future visa denials, bars on re-entry, and other serious immigration consequences. For longer-term plans involving work, study, or family-based residence, specific visa categories exist, each with its own application process through a US embassy or consulate. Begin the process well in advance, as these applications can take considerable time.
