Planning your first independent trip to the US? Besides booking flights and hotels, there’s one more thing to sort out before you go: your ESTA travel authorization.
“Isn’t the US visa-free for Taiwanese passport holders? Why do I still have to apply?” “I searched for ESTA, so why are some sites charging over US$100?” “What if the immigration officer asks why I’m here and my English isn’t great?”
The JEKO team put together this practical guide to answer all of that. The single most important point: Taiwanese passport holders who qualify for the US Visa Waiver Program still need an approved ESTA before departure. Apply only through the US government site at https://esta.cbp.dhs.gov/, and don’t just click the top search result and pay.
Also note that starting October 16, 2026, the official ESTA fee goes up from US$40.27 to US$40.62. If an older article says US$21 or US$40, it’s probably out of date.
1. Do Taiwanese travelers need a US visa? How is ESTA different from visa-free travel?
Taiwan is part of the US Visa Waiver Program (VWP). If you’re eligible and hold a compliant Taiwanese e-passport with an electronic chip, you can generally visit the United States for tourism or permitted business activities for up to 90 days per visit without applying for a regular visitor visa in advance.
But “visa-free” doesn’t mean ESTA-free, and it doesn’t guarantee entry.
| Term | What it means | What travelers need to do |
|---|---|---|
| US Visa Waiver Program (VWP) | Lets eligible travelers skip applying for a regular visitor visa | Check that your passport and personal circumstances qualify |
| ESTA | An electronic travel authorization obtained before departure | Fill in the official system, pay, and get approved |
| CBP inspection | US border officers decide whether to admit you | Show your passport, answer questions truthfully, and go through any required checks |
Not every Taiwanese passport qualifies automatically — for example, conditions related to your passport and national ID number must be met. Travelers who have visited certain countries, hold certain dual nationalities, or have past visa or entry issues may also be ineligible for the VWP. Check the official rules first instead of forcing your way through the ESTA form.
Once approved, an ESTA is generally valid for 2 years or until your passport expires, whichever comes first, and usually covers multiple trips during that time. Each visa-free stay, however, still can’t go beyond 90 days.

2. 2026 official ESTA website and fee: price change from October 16
Type this address straight into your browser:
This is the official ESTA application system run by US Customs and Border Protection (CBP), and the address ends in .gov, a domain reserved for the US government.
2026 official fee table
| Payment date | Total official fee for an approved ESTA | Processing fee if not approved |
|---|---|---|
| On or before 2026/10/15 | US$40.27 | US$10.27 |
| From 2026/10/16 | US$40.62 | US$10.62 |
These are fee changes already announced by the US government. The actual charge is whatever the official page shows at the time you pay; currency conversion and foreign transaction fees from your bank are extra.
Some sites advertise things like “Fast ESTA service US$99” or “Guaranteed approval in 24 hours,” but that doesn’t make them government websites. Legitimate private agencies may also charge a service fee, so you can’t call all of them scams — but paying more doesn’t raise your chances of approval either.
3. How to apply for ESTA: from gathering documents to paying online
Step 1 | Get your passport and contact details ready
The official system currently asks for, or may ask for, the following:
- A valid, VWP-eligible e-passport with an electronic chip.
- A selfie of the applicant, plus a photo or scan of the passport data page.
- A valid email address, home address, phone number, and emergency contact details.
- Your US lodging address or contact information (fill in according to your actual plans).
- Your current employment, other nationalities, travel history, and any other information the system requests.
- A credit card, debit card, or PayPal account to pay with.
Your name, passport number, date of birth, nationality, and passport validity must all match the passport you’ll actually travel on.
Step 2 | Go to the official site and start an application
Click Create New Application, then choose Individual Application. If you’re traveling as a group, you can use the official group application feature, but each person still has to qualify and receive their own authorization — babies and toddlers included.
Step 3 | Photograph your passport and take a selfie
Follow the upload screens shown on the official site at the time, and keep these in mind:
- Get the entire passport data page in the frame — don’t crop off the corners.
- Avoid glare, and don’t let your fingers cover the passport number or the machine-readable zone (MRZ).
- Make sure the text is sharp and the image isn’t blurry.
- For the selfie, make sure your face is clearly visible and follow the app or website prompts; never use someone else’s photo.
- After the system auto-fills your details, still check every field one by one to catch recognition errors.
The photo process on the website and in the official ESTA Mobile App may differ. Don’t confuse the photo size requirements for a US passport or a DS-160 visa application with fixed ESTA specifications.
Step 4 | Fill in your US trip details and eligibility questions
Answer truthfully about the purpose of your trip, lodging, contact details, and the eligibility questions the system asks.
If you’ve been refused a US visa, overstayed before, or have traveled to certain countries, don’t hide it just to get approved. In particular, if you’ve been to Cuba on or after January 12, 2021, or have other travel history or nationality restricted under VWP rules, you may need to apply for a visa instead.
Step 5 | Review, pay, and save your application number
Before submitting, double-check your passport details and email address once more. After paying through the official system, save your application number — you can check back on the official site via Continue Existing Application / Check Status.
Apply as soon as your trip is booked, and allow at least 72 hours. CBP says a decision may take up to about 72 hours, but that doesn’t mean every application is guaranteed approval within a set time. Don’t wait until you’re at the airport check-in counter to start.
4. How to spot ESTA scam and agency sites: six things to check
Search engines may show ads or sites with names very close to the official one. Before you apply, check the following:
- Is the URL exactly right? It should be
esta.cbp.dhs.gov— don’t just look for the word “ESTA.” - Does it claim to be the only government-authorized fast track? There’s no official shortcut where paying more guarantees approval.
- Is the price clearly higher than the official fee? Look carefully for separate service fees and refund terms.
- Does it ask you to send your passport or credit card details in an unfamiliar chat? Be wary of unknown websites and private LINE messages.
- Does it use countdown timers to pressure you? For example, “Pay US$150 now or you’ll be denied entry.”
- Can you check your application status yourself on the official system? Even if you use an agency, keep your own application number and passport details.
Charging more isn’t necessarily a scam, but posing as the government site, making false guarantees, or charging without your consent are all red flags.
5. Does an approved ESTA mean you’ll get in? What do customs officers usually ask?
An approved ESTA lets you travel to the US and request admission — it doesn’t guarantee entry. When you arrive, CBP officers may still ask about the purpose of your trip, how long you’re staying, where you’re staying, and your return plans.
Prepare simple, honest answers in English; there’s no need to memorize a complicated script.
| What the officer might ask | Sample answer in English | What your answer means |
|---|---|---|
| What is the purpose of your visit? | I’m here for sightseeing. | You’re visiting as a tourist. |
| How long will you stay? | I’ll stay for ten days. | You’ll be staying ten days. |
| Where will you stay? | I’m staying at a hotel in New York. | You’re staying at a hotel in New York. |
| Is this your first visit to the U.S.? | Yes, it’s my first time. | Yes, this is your first visit. |
| Do you have a return ticket? | Yes, my return flight is on October 28. | Yes, you fly home on October 28. |
| Who are you traveling with? | I’m traveling with my family. | You’re traveling with your family. |
| What do you do for work? | I’m a web designer in Taiwan. | You work as a web designer in Taiwan. |
| Are you bringing any food? | Yes, I have packaged snacks to declare. | Yes, you have packaged snacks to declare. |
These are just sample situations. Answer based on your real itinerary, and don’t copy anything that doesn’t match your situation. If you didn’t catch what was said, you can say:
Could you please speak more slowly? (A polite way to ask the officer to slow down.)
If you need to check your itinerary, politely ask the officer first whether you can show your flight or hotel details on your phone. Don’t take photos or videos in the inspection area without permission.
6. What documents should you prepare before entering the US? What if your phone has no data?
Before you leave, save the following:
- Your valid passport, ESTA approval status, and application number.
- Your return or onward flight ticket.
- Your first night’s lodging address and booking confirmation.
- A rough itinerary and emergency contact information.
- If you’re bringing food, agricultural products, or other items that must be declared, declare them truthfully as required.
CBP has the authority to carry out entry inspections, and in a small number of cases may also search electronic devices. Don’t count on your phone’s data being instantly available in front of the immigration officer.
The most practical approach is to download important emails and e-tickets ahead of time as PDFs you can open offline, and print a paper copy if needed. That way, even if you haven’t connected after landing, you can still find the right hotel address.
7. Should you set up a US eSIM before you land?
If you plan to call an Uber, look up directions to your hotel, or contact your airport pickup driver right after arriving in Los Angeles, New York, or San Francisco, getting a travel eSIM ready before departure is very convenient.
That said, an eSIM is not required for ESTA review, approval, or entry into the US, and it doesn’t guarantee you can use your phone in the customs inspection area.
Here’s what we recommend:
- Before leaving, confirm your phone supports eSIM and isn’t carrier-locked in a way that blocks it.
- Check whether the plan starts counting “once installed” or “the first time it connects to a supported network.”
- Based on the plan’s rules, decide whether to finish installing it while you’re still in Taiwan.
- After arriving, switch your mobile data to the US eSIM in an area where phone use is allowed.
- Check data roaming and APN settings for your plan, then test Google Maps and your ride-hailing app.
- If you want to keep your Taiwan number active for bank OTPs, separately check overseas SMS and any possible roaming charges.
JEKO’s US travel eSIMs come with different partner carriers and data plans. If you mainly need navigation, Uber, and LINE, compare data-only eSIMs first; if you need a US +1 phone number and regular SMS, choose a plan that clearly includes calls and texts.
US ESTA FAQ
How much is the official ESTA fee in 2026?
It’s US$40.27 through October 15, 2026; the US government has announced it will change to US$40.62 starting October 16, 2026. The amount on the official page when you pay is what counts.
Which is the official ESTA website?
The only official online application system is https://esta.cbp.dhs.gov/. You can also use the official ESTA Mobile App provided by CBP. Don’t rely on search ads to judge whether a site is official.
Do Taiwanese passport holders always need an ESTA to visit the US?
Taiwanese travelers who are VWP-eligible and don’t hold an applicable visa generally need to get an ESTA in advance. However, some people don’t qualify for the VWP because of special status, travel history, or purpose of travel, and need to apply for the appropriate visa.
How long does ESTA approval take?
CBP notes that it may take about 72 hours to get a result. Apply as early as possible once your trip is booked, and don’t treat 72 hours as a guaranteed approval time.
ESTA is valid for two years — does that mean I can stay in the US for two years?
No. Two years is the general validity of the travel authorization. Each visit under the Visa Waiver Program is limited to a maximum of 90 days, and your actual stay is determined at admission.
Do I need to reapply for ESTA if I get a new passport?
Usually, yes. An ESTA is tied to the passport used in the application, so after renewing your passport you should apply again with the new one.
I’ve been to Cuba. Can I still apply for ESTA?
If you visited Cuba on or after January 12, 2021, you’ll likely be ineligible for the Visa Waiver Program and, apart from statutory exceptions, will need to go through the visa process. Confirm based on official US rules and your own circumstances.
Do I need mobile data to show my ESTA when entering the US?
You don’t need to buy an eSIM just for ESTA. Airlines and CBP verify your authorization through their own systems. Still, keeping offline copies of your approval, flight tickets, and lodging address makes things easier if an officer asks for information.
Check the official site first, then back up your key documents
Applying for ESTA isn’t hard. The most common pitfalls are landing on the wrong website, going by an outdated fee, or entering your passport details incorrectly.
Before you go, remember: the only official ESTA address is esta.cbp.dhs.gov, the fee for an approved ESTA is US$40.62 from October 16, 2026, and authorization doesn’t guarantee entry.
Get your flight tickets, booking details, and simple English answers ready, then turn on your travel eSIM once you’ve cleared customs — finding your way, calling a ride, and reaching friends will all go much more smoothly.
