Greensboro Entry Requirements
Visa, immigration, and customs information
Visa Requirements
Entry permissions vary by nationality. Find your category below.
Skip the embassy line. Citizens of the 42 VWP member countries can land in the U.S. for 90 days, no visa, just tourism or business. But don't pack yet. Every VWP traveler must secure an approved ESTA (Electronic System for Travel Authorization) before stepping onto any U.S.-bound carrier. Remember: ESTA isn't a visa. It is a pre-screening authorization tied to your passport.
$21. That is all ESTA costs, no third-party markup, no surprises. Two years of validity, or until your passport expires, whichever comes first. Multiple trips? Covered. Apply only at esta.cbp.dhs.gov; every other site inflates the fee. Denied an U.S. visa before? Been arrested? Traveled to Cuba, Iran, Iraq, Libya, North Korea, Somalia, Sudan, Syria, or Yemen on or after March 1, 2011? Then the Visa Waiver Program is off the table. You will need a B-2 visa, full stop.
Skip the Visa Waiver Program and you'll need a B-2 nonimmigrant tourist visa, no exceptions. Book a consular interview at the nearest U.S. embassy or consulate in your home country. The line forms early. India, China, Brazil, Mexico, Philippines, Vietnam, Nigeria, Pakistan, Egypt, if your passport carries one of these names, you're in the non-VWP club. Same rule applies to most of Latin America, Africa, the Middle East, and Southeast Asia.
Your B-2 visa won't get you past the gate, Customs officers decide at the border. Bring proof you'll leave: job papers, house deeds, family photos. Extensions exist. File Form I-539 if plans change. They're not guaranteed.
Canadian citizens skip both visa and ESTA. Just flash a valid Canadian passport, tourism or business, up to 6 months, you're in.
Non-citizens won't get this perk. Lawful permanent residents of Canada, green-card holders, do not automatically receive this benefit. They may need a visa. Depends on their nationality.
Arrival Process
Your first shock: Greensboro isn't where you'll face U.S. Customs. That happens at your first U.S. stop, period. Most international visitors reach Greensboro through three big hubs, Charlotte Douglas (CLT), Atlanta Hartsfield-Jackson (ATL), or Washington Dulles (IAD). These aren't suggestions; they're the routes airlines use. U.S. Customs and Border Protection (CBP) inspects you at whichever airport you hit first on American soil, not later in Greensboro. Touch down at Piedmont Triad International Airport (GSO) on a domestic connection and you're done, immigration cleared, bags collected, no second screening.
Documents to Have Ready
Tips for Smooth Entry
Customs & Duty-Free
U.S. Customs and Border Protection enforces federal customs rules the same way at every port of entry. Greensboro follows identical duty-free allowances and prohibited items lists as all other U.S. destinations. You'll handle the declaration process at your first port of entry, Charlotte, Atlanta, or whatever hub you connect through, not at Greensboro's airport.
Prohibited Items
- Cuban cigars remain off-limits, no exceptions. The U.S. embargo blocks them everywhere, even if you bought them in London or Toronto.
- Fresh fruit, vegetables, and most unprocessed plant material, USDA bans these. They're keeping agricultural pests and diseases out.
- Most nations won't let you bring in meats, pork from countries still fighting foot-and-mouth disease.
- Fake goods, bags, watches, sneakers, get snatched fast. Importers? They face civil penalties. And criminal ones.
- Narcotics and controlled substances, including marijuana, which stays federally illegal even in states where it is legal
- Firearms and ammunition without proper federal permits and import licenses
- Soil and live plants without USDA permits
- Ivory, certain furs, skins, anything crafted from endangered species is off-limits. Period. These products fall under CITES and the Endangered Species Act, and both laws say no.
Restricted Items
- Prescription medications, keep them in their original labeled container. Bring prescription documentation. Controlled substances? You'll need a letter from your doctor.
- Firearms and ammunition, legal with ATF import permits, full stop. You'll file declarations. CBP must see them.
- Certain food products in commercial quantities, require USDA or FDA clearance
- Cultural artifacts and antiquities, tied up in red tape. Laws protect them. Every source country claims its own.
- Fresh eggs and dairy, allowed from some countries with proper certification. Blocked from others.
Health Requirements
No shots needed. The United States won't ask leisure travelers for vaccination cards at the border, simple as that. Immigrant visa applicants still face different rules, and the government can flip the switch back on for certain conditions without warning. If you land in Greensboro and need help, you've got Moses Cone Hospital and Atrium Health Wake Forest Baptist ready.
Required Vaccinations
- You won't need a single shot to get in. No vaccinations are required for tourist entry to the United States from any country as of March 2026. COVID-19 vaccination rules for air travel died in May 2023, and they haven't come back.
- Immigrant visa applicants, not tourists, must prove vaccination against every CDC-designated disease during their immigration medical exam.
Recommended Vaccinations
- Get the shots. MMR (measles-mumps-rubella), DTP (diphtheria-tetanus-pertussis), varicella, and influenza, check them all.
- COVID-19: CDC recommends being up to date with COVID-19 vaccination before international travel, though it is not an entry requirement
- Hepatitis An and B: Get them. Both shots protect every traveler to the U.S., unless you've had them already.
- Get the shot. North Carolina's flu season runs hot October through April, winter months see the virus rip through crowds, airports, cafés.
Health Insurance
A single U.S. emergency room visit can cost thousands of dollars, no universal healthcare here. One hospital stay? Tens of thousands. Buy travel health insurance that covers emergency medical evacuation and hospitalization. Anything less is reckless. Double-check the fine print: many European and international policies exclude the United States because of the price tag. Some travel credit cards throw in limited medical coverage, scan the terms before you bet your savings on it.
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.
CBP won't ask for notarized letters when both parents fly with their kids. Period. But send a child with one parent, a grandparent, or any other adult and you'd better pack a notarized letter from whoever stayed home, some airlines demand it, and CBP officers can ask. Children under 16 crossing between the U.S. and Canada or Mexico by land or sea can flash birth certificates instead of passports under specific programs. Fly? Every age needs a passport. Each child must hold their own passport, kids cannot piggy-back on a parent's document.
Healthy-looking dogs can still be barred. If your dog is coming from a high-risk rabies zone, most of Latin America, Africa, Asia, Eastern Europe, three things are non-negotiable: microchip, valid rabies shot given in the U.S. or a USDA-accredited foreign lab, and a CDC Dog Import Permit applied for at cdc.gov/importation before you fly. Miss one? Entry denied. Dogs vaccinated outside the U.S. and arriving from these same high-risk countries may be refused on the spot. Cats get a free pass, no federal vaccine or health certificate required. Airlines, however, often demand a health certificate issued within 10 days of travel. Call your carrier. Check Piedmont Triad International's pet facilities while you're at it.
The 90-day clock starts the moment you land, no pauses, no resets. VWP travelers cannot extend or change status from within the U.S. That 90-day limit is firm with virtually no exceptions. Overstay even one day and you're permanently barred from future VWP use. Need more than 90 days? Apply for a B-2 tourist visa before you travel. B-2 visas can be granted for up to 6 months per stay, and extensions can sometimes be requested using Form I-539 from within the U.S. if filed before your authorized stay expires.
Pack pills in their original bottles, no repackaging. For controlled substances, opioids, benzodiazepines, ADHD meds, carry two papers: a copy of the prescription and a letter on your doctor's letterhead stating the medication, dosage, and medical necessity. The DEA won't let you import more than a 90-day supply. Some drugs legal back home are banned stateside, check your exact meds at DEA.gov before you board.
One past U.S. visa denial, and you're out. Immigration violation or certain criminal convictions, including DUI in some circumstances, may slam the door on the Visa Waiver Program regardless of your nationality. No exceptions. You must then apply for a B-2 visa and lay bare the relevant history on your DS-160 application. Try slipping in under VWP while ineligible? That is fraud. Instant denial. Possible lifetime bar from future entry.
