I Made a Mistake on My Form After Submitting It: What to Do

It Happens More Often Than You'd Think

Realizing you made a mistake right after submitting an arrival declaration is one of the most common moments of travel panic and in most cases, it's fixable. What matters is understanding what kind of mistake you made, because the fix is different depending on whether it's a minor typo or something that affects your identity or entry status.

Step 1: Figure Out What Kind of Mistake It Is

Not all errors carry the same weight. Broadly, they fall into three categories:

Minor and low-risk: a typo in your accommodation address, a slightly wrong phone number, a small formatting issue in a date field that's still readable as correct.

Moderate: a wrong flight number, an incomplete customs answer, an email typo that would prevent you from receiving your confirmation.

Serious: a passport number error, a name that doesn't match your passport, or an incorrect visa/entry status. These are the ones most likely to cause a problem at immigration if left uncorrected. See 7 common mistakes for the full list of mistakes that most commonly trigger this.

Step 2: Check Whether You Can Edit or Need to Resubmit

Most official arrival declaration systems don't allow direct editing once submitted, you'll typically need to submit a new, corrected form rather than amend the existing one. A few systems allow limited corrections within a short window after submission. Either way, don't assume the first submission will simply be ignored in favor of a corrected one unless the system confirms that.

If You Applied Through Us: You Don't Have to Start Over

If you applied with us, you don't have to figure out the official resubmission process on your own. From your dashboard, flag the error and our team reviews and prepares the corrected details for you, then guides you through resubmitting them yourself via the official channel. This is one of the main advantages of applying through an assistance service rather than the official portal directly: fixing a mistake doesn't mean starting from scratch or guessing whether your correction went through properly.

Step 3: Resubmit as Soon as You Notice the Error

If a new submission is required whether through the official channel or flagged through your dashboard, do it as soon as you catch the mistake, not the night before your flight. Submission windows are often limited to a few days before arrival, so catching an error early gives you room to fix it properly rather than rushing a second attempt under time pressure.

What If You Only Notice the Mistake at the Airport?

This is the scenario travelers worry about most, and it's manageable in almost every case. If you realize an error shortly before or during your flight:

• If you still have working internet access, resubmit immediately rather than waiting until landing or flag it through your dashboard if you applied with us, so it can be handled while you're still reachable

• If you land before catching it, be upfront with immigration staff most destinations have a process for correcting or completing declarations on the spot, it just takes longer than doing it in advance

• Keep your original passport and booking details on hand so any correction can be made quickly and accurately

When a Mistake Is Serious Enough to Need Extra Help

If the error involves your passport number, your name, or your visa/entry status, it's worth having someone double-check the corrected version before it's resubmitted, these are exactly the fields that cause the bigger issues covered in turned away at the border. A second check catches compounding errors, like fixing one typo while accidentally introducing another.

Not sure how serious your error is?

The Best Way to Avoid Being in This Situation Again

The root cause is almost always the same: submitting quickly, from memory, without the actual documents open in front of you. Keeping your passport, flight confirmation, and accommodation booking visible while filling out any arrival form is what prevents this from happening a second time.

Frequently Asked Questions

Can I edit my arrival declaration after submitting it?
Usually not directly through the official channel, most systems require a new, corrected submission rather than an edit to the original. If you applied through us, you can flag the error from your dashboard and request a corrected resubmission instead of navigating this yourself.

Will my mistake automatically get flagged if I don't fix it?
Not always immediately, but it can cause delays or extra questioning at immigration, especially for identity or visa-related errors, see turned away at the border for what that looks like in practice.

What if I only notice the error after I've already landed?
Inform immigration staff directly, most destinations have a process to correct or complete the declaration on the spot, though it takes longer than fixing it in advance.

Is it risky to resubmit close to my flight?
Not inherently, but it leaves less room to catch a second mistake. Resubmitting as soon as you notice the error is always safer than waiting.
