Common Reasons an ESTA Gets Denied (and How to Avoid Them)

TL;DR

Most ESTA denials in 2026 trace back to one of two causes: a Yes answer on one of the nine eligibility questions (usually question 2 -- arrests and moral-turpitude crimes), or a data-entry mistake that does not match what CBP's systems already hold on you. The single biggest real-world trap is a DUI or drunk-in-public arrest from ten years ago that the traveller assumed was too old to matter -- it is not, and the US government knows about it. The second biggest trap is a passport-number typo that mismatches the biometric chip in your passport. The third is dual nationals forgetting to list their second passport, especially when the second country is on the restricted list (Iran, Iraq, Syria, Libya, Somalia, Sudan, Yemen, Cuba, or North Korea). An ESTA costs $21 in total ($4 processing plus $17 authorization if approved), is valid for two years or until your passport expires, and CBP says most decisions come back within 72 hours though the vast majority resolve in under a minute. If you are denied, you cannot simply reapply -- you need to apply for a B1/B2 visitor visa at a US embassy, which costs $185 and takes weeks. This guide walks through the nine questions, the real reasons people get flagged, and what to do when it goes wrong.

The 9 Official ESTA Questions, Explained

The ESTA form ends with nine eligibility questions, all answered Yes or No. CBP does not publish a ranked list of which ones cause the most denials, but immigration lawyers consistently report that questions 2, 7, and 8 produce the majority of refusals. Here is what each one actually asks in plain English.

Question 1: Physical or mental disorder, drug abuse, or addiction

The formal wording asks about a "physical or mental disorder, or drug abuser or addict." Plain English: do you currently have a condition that could pose a threat to yourself or others, or are you dependent on illegal drugs or alcohol? This is the least-denied question because honest applicants with managed conditions (diabetes, epilepsy, depression on medication) are not the target -- the target is active, untreated addiction.

Question 2: Arrest or conviction for certain crimes

This is the biggest trap. The question covers any arrest or conviction for a crime involving moral turpitude (fraud, theft, violence, domestic abuse) or a controlled-substance offence (possession, supply, trafficking). It is arrest-based, not conviction-based -- an arrest followed by acquittal still counts. Expunged and spent convictions under UK, EU, or Australian law still count because US immigration does not recognise foreign rehabilitation.

Question 3: Controlled substance violations

This overlaps heavily with question 2 but is broader -- it covers any violation of any controlled-substance law, in any country, including laws that are no longer on the books. Cannabis-possession charges from the UK or Germany still count even though cannabis has since been partly decriminalised.

Question 4: Espionage, sabotage, terrorism, or genocide

Most travellers answer No without hesitation. The question is written broadly enough to cover intent as well as action. Lying here is a federal offence under 18 U.S.C. § 1001.

Question 5: Immigration fraud or misrepresentation

Have you ever lied on a US visa, green card, or ESTA application, or helped someone else do so? A Yes here is almost always a permanent bar. Many denials here are self-inflicted because the applicant previously answered No to question 2 on an earlier ESTA, then answered Yes years later on a renewal.

Question 6: Seeking employment in the United States

ESTA is for tourism and business visitors, not workers. Remote work for a non-US employer is a grey area that CBP has quietly tolerated, but paid work for a US employer on an ESTA is grounds for denial and a lifetime ban if discovered at the port of entry.

Question 7: Prior visa refusal, deportation, or overstay

Have you ever been refused a US visa or ESTA, been deported, or overstayed a previous US visit? Any Yes here is usually fatal for ESTA and routes you to B1/B2.

Question 8: Travel to restricted countries since March 2011

Have you travelled to Iran, Iraq, Libya, North Korea, Somalia, Sudan, Syria, or Yemen on or after 1 March 2011? Cuba was added for travel on or after 12 January 2021. Even a single day's transit counts. There are limited exceptions for journalists, diplomats, and military personnel on official duty, but these require supporting evidence at the B1/B2 stage rather than an ESTA workaround.

Question 9: Citizenship of restricted countries

Are you a citizen or national of any of the above countries, including by descent or dual citizenship? This one is non-negotiable -- dual nationals of Iran or North Korea cannot use ESTA at all, regardless of how they entered that citizenship.

Top 7 Data-Entry Mistakes That Cause Denial

A surprising share of denials are not eligibility failures at all -- they are typos. CBP's system cross-checks your entries against the biometric chip in your passport, the API data from your airline, and its own historical records. A mismatch reads as an attempt to deceive.

Mistake	What Goes Wrong	How to Avoid
Passport-number typo	Letter O read as zero, B read as 8, I read as 1	Copy the number from the machine-readable zone (bottom two lines) of your passport
Name mismatch	Middle name on passport but not on ESTA, or vice versa	Type your name EXACTLY as it appears in the MRZ, including all given names
Date format confusion	Europeans writing 04/10/2026 meaning 10 April, not 4 October	The US form uses MM/DD/YYYY -- double-check birth dates
Yes/No flip	Ticking Yes when you meant No on question 2	Re-read every eligibility answer before paying
Wrong country of citizenship	Applicant picks country of residence, not citizenship	Select the country that issued your passport
Missed dual-national passport	Applying on UK passport but also holding Iranian citizenship	Declare every citizenship you hold -- even dormant ones
Wrong parents' birth country	Guessing at parents' birthplace when unsure	Ask your parents before applying; a guess that flags a restricted country is fatal

Any of these will return a Travel Not Authorized response, and you cannot edit a submitted ESTA -- you must wait 10 days and apply again.

DUI, Arrests, and Criminal Records

This is the single most asked question from UK, Irish, and Australian travellers, so here is the honest answer.

A standalone DUI (driving under the influence) is not formally a crime of moral turpitude under US case law -- the Board of Immigration Appeals has consistently held that simple DUI, without aggravating factors, does not require a visa in place of an ESTA. In practice the ESTA online system often still approves DUI applicants whose arrests are more than ten years old and who have a single, clean record since.

But the critical point: you must answer Yes to question 2 anyway, because the question is arrest-based. Answering No and being caught later -- for example on a later visa application or at a port of entry -- is immigration fraud and triggers a permanent lifetime inadmissibility bar that is far harder to fix than a DUI itself.

Since about 2020, CBP has tightened enforcement. Applicants with any of the following are now routinely denied ESTA and pushed to B1/B2:

• Multiple DUIs (even with no injury)
• DUI with a minor in the vehicle
• DUI causing injury or death
• DUI combined with any other arrest
• Any drug-related arrest at any time in life, however minor

At the B1/B2 stage a consular officer can consider rehabilitation evidence, length of time since offence, and the specifics of the charge. The ESTA system cannot -- it is a binary Yes/No gate.

Arrests without conviction

US immigration does not distinguish between arrest, charge, and conviction for the purpose of question 2. If you were arrested for shoplifting when you were 17, cautioned and released, and the record was later sealed -- you still say Yes. The same applies to dropped charges, acquittals, and foreign expungements. The US government frequently has access to arrest records even when your home country considers the matter closed.

Post-2011 Travel to Flagged Countries

The Terrorist Travel Prevention Act of 2015 (and its 2021 Cuba amendment) block ESTA eligibility for anyone who has visited a list of countries. The current list is Iran, Iraq, Libya, North Korea, Somalia, Sudan, Syria, Yemen, and Cuba.

Dates matter. The cut-off is travel on or after 1 March 2011 for the first eight countries and travel on or after 12 January 2021 for Cuba. Travel before those dates does not block ESTA.

One-day transits count. Passing through Tehran airport for a connection, a port call at a Cuban harbour on a cruise, a day trip across the Sudan border for a journalist -- all of these are disqualifying.

There are narrow exceptions for military service on US-allied duty, for official diplomatic travel, and in some cases for journalists and NGO humanitarian workers, but these exceptions are processed through B1/B2 visa applications with supporting documentation. The ESTA system cannot evaluate them and will simply deny.

Dual nationals of any of these countries -- including people who acquired the citizenship at birth through a parent and have never visited -- are blocked from ESTA entirely, regardless of which passport they travel on.

Pending vs Denied -- What Each Means

When you submit your ESTA you will see one of three statuses.

Authorization Approved. Your ESTA is granted. Valid for two years or until passport expiry.

Travel Not Authorized. This is a denial. Your $4 processing fee is kept; the $17 authorization fee is not charged. You cannot use ESTA for this trip. Apply for B1/B2 instead.

Authorization Pending. CBP is manually reviewing your file. This usually clears within 72 hours. Most pending cases resolve with Authorization Approved, but a meaningful minority flip to Travel Not Authorized after review. You cannot speed up a pending review, and CBP will not discuss it with you by phone.

A pending status is not itself a denial. If you have flights booked within the 72-hour window and your status is still pending, you should assume the worst and prepare a back-up -- either reschedule or begin a B1/B2 visa application.

ESTA Application Walkthrough, Step by Step

This is how to fill out an ESTA application correctly from scratch. Use the official site only: esta.cbp.dhs.gov. There are many copycat sites charging $70 to $100 for a service that costs $21 direct -- they are all legal but all overpriced.

1. Open the official ESTA portal. Go to esta.cbp.dhs.gov and select Apply. Choose single application (or group if you are applying for family members).
2. Enter passport details. Type the passport number exactly as printed on the biometric page -- the easiest way is to use the bottom two machine-readable lines. Upload or take a selfie photo that matches the passport photo style (plain background, face centred, no glasses).
3. Answer personal detail questions. Full name as printed, date and place of birth, current address, emergency contact. List every other citizenship you hold, including dormant ones.
4. Answer travel details. Your intended US address (hotel is fine for the first night), flight details if known (can be left blank if you have not booked yet), and whether you are in transit to another country.
5. Answer the nine eligibility questions. Read every one twice before answering. If you are unsure about any Yes, stop and consult an immigration lawyer before submitting -- a Yes is not automatically a denial, but a wrongly-flipped answer is almost impossible to correct.
6. Review and certify. CBP shows you a summary of every answer. Check every field -- this is your last chance to catch typos. Sign the attestation.
7. Pay the $21 fee. $4 processing (non-refundable) plus $17 authorization (only charged if approved). Credit/debit card or PayPal. You will get an application number -- save it.

Most applications return Authorization Approved in under a minute. You will not get an email until the decision is made -- check your status at esta.cbp.dhs.gov using your application number, passport number, and date of birth.

ESTA Processing Time in 2026

CBP's official answer is "up to 72 hours." The real-world numbers:

• About 90% of applications approve in under 60 seconds
• About 8% return Authorization Pending and resolve within 24 hours
• About 2% stay pending for the full 72 hours
• A very small number go beyond 72 hours, usually because of a name-match issue with a watch list

Weekends and US public holidays do not slow processing -- the ESTA system is automated and runs 24/7, and the human reviewers work rolling shifts. There is a mild holiday backlog around Thanksgiving and the December holidays when application volume spikes.

Apply as early as you can. CBP recommends applying "as soon as you begin preparing for your trip." There is no penalty for applying early -- the two-year validity clock starts from the date of approval, not the date of travel.

What Happens If You're Denied

Travel Not Authorized on an ESTA is not the end of your trip, but it does mean you cannot fly without further action. You have three practical options.

Option 1: Apply for a B1/B2 visitor visa. This is the correct path for anyone denied ESTA on eligibility grounds. The visa costs $185, requires an in-person interview at a US embassy or consulate, and currently takes 4 to 8 weeks depending on location (London is faster, Berlin is slower, Sydney is variable). The B1/B2 is valid for up to 10 years and allows stays of up to 6 months at a time.

Option 2: Reapply for ESTA after 10 days. Only use this if you genuinely made a data-entry mistake the first time. Do not use it to try a different set of Yes/No answers -- CBP keeps every submission and flags material inconsistencies as attempted fraud.

Option 3: Cancel the trip. If your trip is time-sensitive and B1/B2 will not arrive in time, you will need to rebook. Most travel insurance policies consider visa denial a covered reason for cancellation if you purchased cover at the time of booking -- check your policy.

Reapplying Correctly

If you are reapplying after a data-entry denial, follow these rules:

• Wait at least 10 calendar days
• Correct only what was genuinely wrong
• Do not change any substantive answer (Yes/No on eligibility questions)
• Keep the original application number for your records
• Expect a longer pending review on the second attempt

CBP also runs an internal process called Admin Fix or AP (Administrative Processing) where an application is held open for additional checks. You do not apply for AP -- it happens automatically, and you will see a Pending status for longer than usual. AP typically resolves within 10 business days.

ESTA Validity, Renewal, and Multi-Entry

An approved ESTA is valid for two years from the date of approval, OR until your passport expires -- whichever comes first. If your passport expires in 6 months, your ESTA is valid for 6 months.

ESTA is a multiple-entry authorization. You can enter the US as many times as you like during its validity, but each stay must be 90 days or less, and CBP will review the overall pattern -- back-to-back 90-day stays look like residence and will be questioned at the port of entry.

When you renew your passport, you must apply for a new ESTA. There is no way to transfer an existing ESTA to a new passport. The same is true if you change your name, change your gender marker, change your country of citizenship, or answer any of the nine questions differently than before.

Check ESTA Status, Urgent Applications, and Helpline

To check the status of an application you have already submitted, go to esta.cbp.dhs.gov and select Check ESTA Status. You will need your application number, passport number, country of citizenship, and date of birth. If you have lost your application number you can retrieve it using the Payment Record lookup with your payment-card details.

Urgent ESTA applications. There is no official expedited track. The system is already close to real-time, so "urgent" in the ESTA world simply means applying at least 72 hours before scheduled departure. Airlines will refuse boarding without an approved ESTA, and you cannot apply at the gate.

The ESTA helpline. CBP operates a general contact form at help.cbp.gov, but it is not a real helpline -- there is no phone number you can call to speed up a pending application or dispute a denial. Response times by email run to 7 to 14 days. Third-party helpdesks that advertise ESTA phone support are all unofficial and have no influence over CBP decisions.

Red Flags That Trigger Travel Not Authorized

A quick checklist of issues that, honestly, will get you denied:

• Any arrest record anywhere in the world that you answer No to
• Previous visa overstay in the US (even a few days)
• Previous visa refusal for any US visa category
• Dual citizenship with Iran, Iraq, Syria, Libya, Somalia, Sudan, Yemen, Cuba, or North Korea
• Travel to any of those countries since 1 March 2011 (Cuba since 12 January 2021)
• Employment history that looks like you will work in the US
• Passport issued by a non-VWP country
• Name or date-of-birth mismatch with an Interpol or US watch list
• Prior ESTA denial that you are simply retrying without change

If more than one of these applies to you, do not waste time on ESTA -- apply for B1/B2.

ESTA vs B1/B2 Visa -- Which Do You Actually Need?

Situation	Best Option
UK/EU/AU/NZ citizen, clean record, tourism, <90 days	ESTA
UK/EU/AU/NZ citizen, any arrest history	B1/B2
UK/EU/AU/NZ citizen, travel to Iran/Iraq/etc since 2011	B1/B2
Dual national of restricted country	B1/B2 only
Stay longer than 90 days	B1/B2
Paid work in the US	H-1B, L-1, or other work visa
Study at US college	F-1
Journalist on assignment	I visa
Cruise ship transit only	ESTA often works but confirm with cruise line

For the full ESTA process and a comparison with other visa categories, see our US ESTA and visa guide for 2026. For everything else you need to plan a US trip, the USA travel guide 2026 covers budgets, itineraries, and regional breakdowns. You can also start a visa application directly through our visa help page, and check cover options on our travel insurance page -- travel insurance is not a US entry requirement but is strongly recommended given US healthcare costs.

The ESTA system is fast, cheap, and reliable for the majority of Visa Waiver Program travellers -- but it is also unforgiving of mistakes and honest about its hard eligibility lines. If you answer the nine questions truthfully, type carefully, and apply at least 72 hours before your flight, you will almost certainly be approved. If any of the red flags apply to you, do not gamble with a $21 ESTA -- pay the $185 and get a B1/B2 visa, where a consular officer can actually look at your file.
