US Visa Guide 2026: ESTA vs B-1/B-2 and Interview Tips

1. Traveling to the U.S.: Do You Need ESTA or a Visa?

Whether you need a visa to travel to the United States depends on your passport nationality, purpose of travel, and length of stay, not the country where you live or work. In one sentence: if you hold a passport from a country or region eligible for the Visa Waiver Program (VWP), are traveling for tourism or short-term business, and plan to stay no more than 90 days, you generally only need to apply for ESTA; if you do not qualify for ESTA, or plan to stay longer than 90 days, you generally need to apply for a B-1/B-2 visitor visa. The vast majority of B-1/B-2 applicants must attend an in-person interview; only renewal applicants who meet specific conditions may be exempt (as of November 2026, source: U.S. Department of State).

Answering three questions will pinpoint your situation: Which country issued your passport? What is the main purpose of your trip to the U.S.? How many days do you plan to stay? Compare with the table below:

How to decide: first check whether your passport nationality is on the VWP list, then check the length of stay. Only if both conditions are met should you go the ESTA route; if either one is not met, prepare for a B-1/B-2. Don't judge based on "which country I live in"—the deciding factor is passport nationality.

2. What Is ESTA, How Do You Apply, and How Much Does It Cost?

ESTA (Electronic System for Travel Authorization) is not a visa; it is a pre-screening of eligibility for VWP travelers before traveling to the United States. The VWP currently covers 42 countries or regions, and eligible travelers may travel to the United States visa-free for tourism or short-term business for a maximum stay of 90 days, but must obtain a valid ESTA approval before boarding a plane, boarding a ship, or entering by land (as of November 2026, source: CBP Visa Waiver Program).

Fees and key parameters:

Application steps: Confirm that your passport is issued by a VWP-eligible country and is a valid electronic passport → Go to the official CBP ESTA website → Fill in personal, passport, travel information and eligibility questions → Pay the application fee → Save the application number and approval status → Reconfirm before departure that it is still valid. CBP recommends submitting as early as possible when you begin planning your trip and before purchasing airline tickets, and not delaying until one or two days before departure.

Document checklist:

Common mistakes: Treating ESTA as a visa; using unofficial agent websites and paying high "service fees"; name spelling, passport number, or date of birth not matching the passport; failing to recheck whether the ESTA is still valid before departure; treating approval as a guarantee of entry; staying beyond 90 days.

Verdict: ESTA suits short-term travelers who qualify under the VWP, saving money and time; but it does not guarantee entry, and it cannot be used for work or full-time study. Only trust the official ESTA website (esta.cbp.dhs.gov); any third party charging "expedited fees" or "guaranteed approval fees" is not trustworthy.

3. How do I apply for a B-1/B-2 visa, and is an interview required?

The B-1/B-2 visitor visa is for travelers who do not qualify for ESTA, plan to stay longer than 90 days, or prefer to enter the U.S. on a visa. B-1 is for short-term business (meetings, negotiations, inspections), B-2 is for tourism, visiting relatives, and medical treatment, and B-1/B-2 covers combinations of both (source: U.S. Department of State Tourism & Visit).

Application process: Confirm you do not qualify for ESTA or will stay >90 days → Complete the DS-160 nonimmigrant visa application online → Prepare a photo meeting the specifications → Pay the visa application fee (MRV fee; the amount is subject to what is posted on the day by the U.S. Department of State and your consular district's appointment system) → Schedule an interview at your consular district → Attend the interview at the scheduled time → After visa issuance, enter according to the validity period on the visa page. The DS-160 must be submitted online, and the confirmation page must be printed and brought to the interview.

Is an interview required? For the vast majority of B-1/B-2 applicants, yes. As of October 1, 2025, the U.S. Department of State requires that all nonimmigrant visa applicants—including those under 14 and over 79—generally appear for an interview; only specific categories or eligible B visa renewal applicants may be exempt (as of November 2026, source: U.S. Department of State Interview Waiver Update).

Circumstances that may qualify for an interview waiver (all must be met):

• Renewing a B-1, B-2, or B-1/B-2 visa within 12 months after expiration;
• The previous visa was issued for the full validity period;
• You were at least 18 years old at the time of application;
• Applying in your country of nationality or country of usual residence;
• Never refused a visa, or the refusal has been overcome/waived;
• No apparent or potential grounds of ineligibility.

Even if all conditions are met, a consular officer may still require an interview on a case-by-case basis.

Verdict: Do not assume by default that "elderly people and children do not need an interview" — as of October 2025, this is no longer valid. For first-time applicants, or those who do not meet the above renewal exemption conditions, prepare time and documents on the basis that an interview is required.

4. What is asked at the interview, and which documents should you bring?

Visa officers usually do not ask complex questions; the key is truthful, concise answers consistent with the DS-160. Common questions and suggested ways to answer:

Document checklist:

Verdict: The core purpose of the documents is to prove that "you will return on schedule" — stable work, income, family, and asset ties are more persuasive than the deposit figure itself. Do not provide false invitation letters, false employment certificates, false itineraries, or false financial documents; inconsistencies or false statements may affect future applications.

5. What if the visa is refused?

A visa refusal does not mean you can never go to the United States, but do not immediately reapply with the same materials. First determine the reason for refusal, then adjust your strategy. Common reasons: unclear purpose of travel; itinerary inconsistent with financial capacity; insufficient proof of ties to country of residence/country of nationality; inconsistency between DS-160 information and interview answers; prior records of overstaying, unauthorized work, or fraudulent materials; failure to clearly explain the purpose of visiting the U.S. and plans to return home.

Before reapplying, you should: check whether the DS-160 and interview answers are consistent; supplement authentic, verifiable financial and ties documentation; adjust the itinerary so it matches the applicant's identity, age, income, and family situation; do not fabricate itineraries or relationships in order to "improve the approval rate."

Assessment: after a refusal, what you most need to do is "strengthen evidence of ties + make the itinerary more reasonable," not switch to another agency or repeatedly submit the same materials.

6. When to book flights and hotels, and how to connect with tour dates?

The U.S. Department of State explicitly recommends: do not make final travel plans or purchase airline tickets before obtaining a visa; a visa itself does not guarantee entry (Source: U.S. Department of State). Operate by stage:

Once visa or ESTA status is clear, verify three things with USITrip: whether the selected dates still have availability; whether the tour price includes hotels, transportation, tickets, and gratuities; whether the cancellation policy allows you to adjust if visa, flight, or family arrangements change. USITrip cannot guarantee visa or ESTA outcomes and cannot replace official immigration advice, but after travel authorization is confirmed, it can turn destination, dates, number of travelers, and budget into a sellable group tour itinerary.

For example, a traveler holding a VWP passport planning a 10-day trip to the U.S. West in October can refer to these two itineraries covering Grand Canyon National Park, Universal Studios Hollywood, and the Las Vegas Boulevard area (prices are tour fees, as of November 2026, source: USITrip product pages):

(CNY converted at 1 USD≈6.67 CNY; exchange rate as of November 11, 2026; tour fees do not include international airfare, visa/ESTA fees, gratuities, or optional items; see the product page for item-by-item details.)

Judgment: Travelers from non-VWP countries who need a B-1/B-2 visa must first confirm the visa result before locking in non-refundable/non-changeable hotels, tickets, or tour dates; travelers whose ESTA has been approved can book refundable/changeable tour dates earlier.

7. Frequently Asked Questions (FAQ)

Q1: Can ESTA replace a U.S. visa?

A: It is only valid for travelers who meet VWP conditions. ESTA is not a visa, but a travel authorization for eligible travelers; travelers who do not meet the conditions still need to apply for a visa.

Q2: Does ESTA approval guarantee entry into the United States?

A: No. ESTA approval only indicates that you are eligible for VWP travel; upon arrival at a U.S. port of entry, CBP officers still decide whether to admit you.

Q3: How long is a B-1/B-2 visa valid?

A: The validity period shown on the visa page is the time range during which it may be used for entry, and is not equal to the length of time you may stay in the United States; the actual length of stay is determined by CBP at the time of entry.

Q4: Can I work in the United States with ESTA?

A: No. ESTA applies to eligible short-term tourism or business travel and may not be used for employment in the United States.

Q5: Can I stay in the United States for more than 90 days?

A: If you do not meet ESTA conditions or plan to stay longer than 90 days, you should generally apply for a B-1/B-2 visa; do not attempt to overstay through ESTA.

Q6: Do Canadian citizens need a visa to travel to the United States?

A: Canadian citizens generally do not need a nonimmigrant visa for tourism to the United States, except for specific travel purposes or eligibility circumstances; Canadian permanent residents, however, generally need a nonimmigrant visa (Source: U.S. Department of State).

Q7: Do applicants under 14 or over 79 still need an interview?

A: As of October 1, 2025, an interview is generally required; only specific categories or eligible B-class renewal applicants may be exempt, and consular officers may still require an interview on a case-by-case basis.
