Thousands of Vietnam eVisa applications succeed each week, but a predictable set of mistakes causes rejections or airport stress. Review this list before you pay on /apply—fixing errors after submission costs time and sometimes requires a new filing.
We are a private visa assistance service—not the Government of Vietnam. We help you catch typos and document issues early; we do not replace official immigration decisions.
1. Passport number typos
Transposing digits or dropping leading zeros is the top delay. Read the machine-readable zone at the bottom of your bio page character by character.
2. Wrong date of birth format
Use the passport’s DD/MM/YYYY order as shown—not the US-style month/day habit.
3. Selecting the wrong entry port
Your approval is valid for the airport or border you chose. Flying into Da Nang while the letter says Hanoi creates entry risk. See /blog/vietnam-evisa-approved-entry-ports-2026.
4. Single-entry visa used twice
Leaving Vietnam for a side trip to Thailand then returning requires multiple entry if your first visit consumed the single entry. Verify your visa type on the PDF.
5. Photo that is not passport-style
Selfies, sunglasses, and patterned walls fail automated checks. Follow /blog/vietnam-evisa-photo-requirements-2026.
6. Expired or short-validity passport
You need typically six months validity beyond arrival and at least one blank page.
7. Tourism visa for paid work
Remote work for Vietnamese clients, teaching, or local employment need proper permits—tourist eVisas do not authorize employment in Vietnam.
8. Ignoring email after submission
Approval or fix requests go to the inbox you typed. Check spam folders for 72 hours.
9. No printed copy at check-in
Airlines and immigration may require paper. Save the PDF offline on your phone and print one copy.
10. Applying too late
Same-day travel is risky. Read /blog/vietnam-evisa-processing-time-2026 and apply early.
Bonus: duplicate applications
Paying twice because the first seemed slow can create conflicting records. Track one reference number; contact support before submitting again.
What happens at the airport if you made a mistake?
Airlines scan passports at check-in. Common outcomes:
- MRZ mismatch → boarding denied until you reapply
- Wrong entry port → immigration supervisor delay or refusal
- Expired passport → no boarding, no airline refund for visa issues
Immigration police have the final say even if the airline let you fly. Treat the eVisa PDF as a contract: every field must match your passport.
Fixing errors before submission
| Stage | Action |
|---|---|
| Before payment | Edit fields in the application draft |
| After payment, before processing | Contact support immediately with reference ID |
| After approval | Corrections usually require a new application |
| After rejection | Fix root cause; wait cooling-off if instructed |
Never pay twice without support guidance—duplicate records trigger fraud filters (rejection guide).
Business travelers: extra pitfalls
- Listing conference sponsor as employer without a business visa
- Local client invoices in luggage—customs and immigration may question intent
- Equipment imports requiring separate permits
Tourism eVisas are for leisure. Repeated business trips may need embassy stickers—see /embassy.
Families: mistakes multiplied
- Applying only for parents while children have passports
- Different entry dates per child vs adult
- Child photo with parent’s shadow in frame
Use /blog/vietnam-evisa-for-minors-families-2026 for group filing.
