Vietnam E-Visa Mistakes: 10 Errors That Get You Denied

Every year, thousands of Vietnam E-Visa applications are rejected — not because applicants are ineligible, but because of small, avoidable mistakes made during the online application process. A blurry passport scan, a reversed name field, or a wrong arrival date can cost you your non-refundable application fee and, worse, put your travel plans at risk.

The good news: nearly all of these errors are fixable. This guide covers the 10 most common E-Visa application mistakes in 2026, explains why each one triggers a rejection, and tells you exactly how to avoid it.

How Vietnam E-Visa Rejections Work

Before diving into the mistakes, it helps to understand how the system handles problems. When you submit an E-Visa application, it passes through the Vietnam Immigration Department's automated checks and then a manual review. Your application will land in one of these statuses:

• Processing — your application is in the queue and under review. Standard processing takes 3 working days (excluding weekends and Vietnamese public holidays), but can stretch to 5-7 during peak periods.
• Amendment Required — something needs to be corrected. This is not a rejection. You can fix the flagged issue and resubmit, but the processing timer resets from the beginning.
• Rejected — your application has been denied. You will need to submit an entirely new application after correcting the issue.
• Approved — your E-Visa has been issued. Download the PDF immediately.

Two critical things to know:

1. The application fee is non-refundable, even if your application is rejected. Every rejection costs you money.
2. There is no mandatory waiting period to reapply after a rejection. You can submit a new application immediately — as long as you fix the problem first.

Mistake 1: Non-Compliant Portrait Photo

This is the single most common cause of E-Visa rejection. The Immigration Department's system uses AI to scan uploaded photos automatically, and it is strict.

Your portrait photo must meet all of the following requirements:

• Size: 4 x 6 cm (standard passport photo proportions)
• Format: JPG or JPEG only (not PNG, HEIC, or PDF)
• File size: Under 2 MB
• Background: Plain white, no patterns or objects
• Pose: Front-facing, eyes open, neutral expression, mouth closed
• Accessories: No glasses, no hats, no headwear (unless religious)
• Recency: Taken within the last 6 months

Common failures that trigger rejection:

• Selfies taken at an angle or with a phone's front camera (distorts perspective)
• Colored, outdoor, or patterned backgrounds
• Sunglasses or regular glasses left on
• Face too small in the frame, or top of head cropped off
• Heavy filters or photo editing
• Photos of printed photos (scanning a printed passport photo reduces quality)
• Shadows on the face or behind the head

How to fix it: Stand against a plain white wall in even, natural lighting. Have someone else take the photo from about one meter away. Face the camera directly with a neutral expression. Remove all glasses and hats. Crop to 4 x 6 cm proportions, ensuring your full face and upper shoulders are visible. Save as a JPG file under 2 MB.

Do not use a phone selfie. The perspective distortion from a close-range front camera is one of the most common reasons photos fail the automated check.

Mistake 2: Blurry or Cropped Passport Scan

The application requires a scan or photograph of your passport's bio page — the page with your photo, name, nationality, passport number, and the two machine-readable lines (ICAO lines) at the bottom. The system uses optical character recognition (OCR) to read this page and auto-fill your application. If the scan is poor, the OCR either misreads your data or the upload is rejected outright.

Common failures:

• Phone flash creating glare on the laminated surface (the single most reported scan issue)
• Bottom edge cropped, cutting off the ICAO machine-readable lines
• Image too dark, too light, or out of focus
• Wrong file format (PNG, HEIC, or PDF instead of JPG)
• File size exceeding 2 MB

How to fix it: Lay your passport flat on a dark surface in a well-lit room. Use natural or overhead light — do not use your phone's flash, as it bounces off the laminated page and creates white glare across the text. Capture all four corners of the bio page. Pay special attention to the two lines of characters at the very bottom of the page (the ICAO lines) — these are what the OCR reads first, and cutting them off even slightly will cause a rejection.

Save the image as a JPG file under 2 MB. Before uploading, zoom in on your phone screen and verify that every line of text is sharp and legible.

Mistake 3: Passport Number Typos

Even a single wrong character in your passport number will result in either a rejection or, worse, an approved E-Visa that does not match your passport — which means you will be denied boarding or turned away at Vietnamese immigration.

The most common typos involve characters that look similar:

• O (letter) vs 0 (zero)
• I (letter) vs 1 (number)
• Missing or extra characters
• Incorrect issue or expiry dates

There is an additional risk here: the OCR system that reads your passport scan auto-fills the passport number field on the application form. If your scan has glare or is slightly blurry, the OCR may misread characters. Many applicants trust the auto-filled data without checking it, and submit an application with an incorrect passport number they never actually typed.

How to fix it: After the system auto-fills your details from the passport scan, compare every character of the passport number field against your physical passport. Read each character out loud if it helps. Pay special attention to any character that could be either a letter or a number. Do not assume the auto-fill is correct.

Mistake 4: Name Does Not Match Passport

Your full name on the E-Visa application must match your passport character for character. This includes middle names, hyphens, capitalization, and name order. Even a single-letter difference can trigger a rejection or create a mismatch that causes problems at immigration.

Common failures:

• Reversing surname and given name (putting your first name in the Surname field)
• Omitting middle names entirely
• Dropping hyphens in hyphenated names
• Spelling variations ("Mc" vs "Mac", "Mohammed" vs "Muhammad")
• Shortened or informal names instead of the full legal name on the passport

The Vietnamese E-Visa form uses "Surname" and "Given Name" fields. Your surname is your family name (last name). Your given name includes your first name and all middle names. Enter them exactly as they appear on your passport's bio page, in the same order.

How to fix it: Open your passport to the bio page. Copy the surname exactly as printed in the "Surname" field, and copy the given names exactly as printed in the "Given Name" field. Include every middle name. Do not abbreviate, reorder, or drop any part of your name.

Mistake 5: Wrong Entry Port

Your Vietnam E-Visa is only valid at the specific port of entry you declare on the application. Vietnam currently has 83 ports that accept E-Visas, including 17 international airports, 27 land border crossings, and 39 seaports. If you register for Noi Bai Airport (HAN) in Hanoi but fly into Tan Son Nhat (SGN) in Ho Chi Minh City, your E-Visa is invalid at SGN.

This mistake is particularly costly because airlines verify your E-Visa at the boarding gate. If your declared entry port does not match your flight destination, you can be denied boarding before you even reach Vietnam.

Common scenarios:

• Booking a different flight after submitting the application
• Confusing airport codes (HAN vs SGN vs DAD)
• Selecting the wrong port from a long dropdown list
• Changing travel plans without updating the visa

How to fix it: Finalize your flight itinerary before submitting the E-Visa application. Confirm which airport or border crossing you will actually enter Vietnam through. Double-check the entry port field before submitting. If your plans change after approval, you cannot amend the existing visa — you must apply for a new E-Visa with the correct entry port.

Mistake 6: Wrong Entry Date

You can only enter Vietnam on or after the entry date stated on your E-Visa. You cannot enter even one day early. An incorrect entry date will either cause a rejection during processing or leave you with a valid visa that does not cover your actual arrival.

Common failures:

• Entering your departure date from your home country instead of your arrival date in Vietnam
• Late-night flights that arrive after midnight — your entry date is the next calendar day, not the day you boarded
• Entering a date that has already passed (immediate rejection)
• Selecting the wrong month by accident

How to fix it: Check your flight's scheduled arrival time in Vietnam, not the departure time from your origin. If your flight departs at 11 PM and lands at 1 AM the next day, your entry date is the next day. Use the date picker on the form carefully and verify the date before submitting.

Mistake 7: Passport Expires Within 6 Months

Vietnam requires your passport to be valid for at least 6 months from the date you enter the country. If your passport expires sooner than that, your application will be flagged for additional review or rejected outright.

This catches more travelers than you might expect. Many people check their passport, see several months of validity remaining, and assume they are fine — without counting whether those months add up to six from their arrival date.

How to fix it: Before starting your E-Visa application, check your passport's expiry date. Count forward 6 months from your planned arrival date in Vietnam. If your passport expires before that 6-month mark, renew it before applying.

For example: if you plan to enter Vietnam on October 15, 2026, your passport must be valid until at least April 15, 2027.

Mistake 8: Missing or Vague Accommodation Address

The E-Visa application requires a specific accommodation address in Vietnam — a hotel name, serviced apartment, or residential address where you will stay. Vague entries like "hotel in Hanoi" or "TBD" or leaving the field blank will result in a rejection or an amendment request.

The address does not need to be a confirmed booking. You do not need to have paid for the hotel. But it must be a real, specific place with a full address.

How to fix it: Before starting the application, look up a hotel or accommodation in the city where you will first stay. Enter the full name and address, including the street, district, and city. If you have not booked accommodation yet, search for any hotel in your destination area and enter its address. You can change hotels after your visa is approved — the immigration officer will not cross-check your hotel booking at the border.

Mistake 9: Applying Too Late

The official processing time for a Vietnam E-Visa is 3 working days. The key word is "working." Weekends and Vietnamese public holidays are excluded. A Friday evening application does not start processing until Monday morning.

In practice, processing can take 5-7 calendar days — and longer if your application is flagged for amendment (which resets the processing timer) or if you apply during a peak period.

Periods that cause significant delays:

• Tet (Lunar New Year): Government offices shut down for 7+ days. Backlogs after the holiday add another 3-5 days.
• April 30 / May 1 (Reunification Day and Labor Day): Often extended to a 4-9 day break.
• September 2 (Independence Day): 2-3 day stoppage if it falls near a weekend.
• General peak months (January-April, November-December): Higher application volumes push processing toward the 5-day end.

How to fix it: Apply at least 10 working days before your travel date. If your trip falls near a Vietnamese public holiday, apply 15-20 working days in advance. The E-Visa is valid for up to 90 days from the granted entry date, so applying early costs you nothing. Do not calculate based on "3 days" — build in a buffer for weekends, holidays, and possible amendment requests.

Mistake 10: Payment Fails Without You Knowing

The government E-Visa portal's international payment gateway frequently declines foreign credit and debit cards. The most common cause is your bank's fraud detection system flagging the .gov.vn merchant as suspicious and blocking the transaction. Prepaid debit cards are also often rejected.

The dangerous scenario: your bank shows a "pending" charge, so you assume payment went through. But the portal registered the payment as failed, meaning your application was never actually submitted. You only discover this days later when you check the status and find it listed as "Unpaid" — with your travel date approaching.

How to fix it:

1. Before applying: Call your bank or use your banking app to temporarily enable international transactions or whitelist the merchant. Mention you are making a payment to the Vietnamese government immigration portal.
2. After paying: Check the portal immediately to confirm the application status shows "Processing" (not "Unpaid"). Do not rely on email confirmation alone.
3. If payment is declined: Try a different card. Visa and Mastercard are accepted. If your card is repeatedly declined, a different bank or card issuer may work.

What to Do If Your E-Visa Is Rejected

If your application is rejected, follow these steps in order:

Step 1: Identify the reason

Log in to the portal with your registration code and check the rejection notice. The system sometimes provides a specific reason, but often gives a generic message like "application error." If the reason is unclear, check your photo and passport scan first — these are by far the most common causes.

Step 2: Fix the specific issue

Do not reapply with the same information. If the photo was the problem, take a new one. If the passport number was wrong, verify every character. If the entry date was incorrect, recalculate based on your flight arrival time.

Step 3: Submit a brand new application

You cannot edit or resubmit a rejected application. Start a completely new one from scratch. Fill in every field carefully, double-checking each piece of information against your physical passport. There is no waiting period — you can reapply immediately.

Important: Do not submit a duplicate application while an existing one is still in "Processing" status. Submitting two applications with the same passport data can create conflicts in the system and cause both to be rejected.

If your status shows "Amendment Required"

This is not a rejection. The system is asking you to correct something — usually a non-compliant photo, incorrect passport number, or missing accommodation address. Log in, fix the flagged issue, and resubmit. However, be aware that the processing timer resets from the beginning once you resubmit the correction.

Quick Reference: 10 Mistakes at a Glance

The Bottom Line

The vast majority of Vietnam E-Visa rejections come from preventable mistakes — a bad photo, a typo, or a miscalculated date. The application itself is straightforward, but the system has zero tolerance for errors and the fee is non-refundable.

Before you submit, take five minutes to run through the checklist above. Verify your photo meets the requirements. Compare every auto-filled field against your physical passport. Confirm your entry port and date match your actual itinerary. Check that your payment went through.

Those five minutes can save you the cost of a second application, days of processing delays, and the stress of watching your travel date approach without an approved visa in hand.
