Scenario 2 — Applied With Wrong Port (SIN/ICN Entered Instead of SGN/HAN)
The eVisa portal accepts any IATA code without geographic validation. Many travelers at SIN, ICN, or BKK entered the transit hub as entry port instead of the Vietnamese airport. This triggers Amendment Required with no email. The fix is free and takes approximately 30 minutes.
| Situation | Action | Cost |
|---|---|---|
| Applied SIN/ICN — status Amendment Required | WhatsApp Reference Code + email + flight. Port corrected, resubmitted priority. Boarding Letter bridge. | Free |
| Applied SIN/ICN — status In Process | WhatsApp Reference Code + email + flight. Port corrected before approval. Speed Up to priority. | From USD 65 |
| No eVisa applied at all | WhatsApp passport photo + flight number. New application on priority. Boarding Letter bridge. | From USD 185 |
| Two applications submitted | WhatsApp both Reference Codes. Deduplication hold 24–48h. Boarding Letter bridge immediately. | Free assessment |
Scenario 3 — At SGN or HAN Airport in Transit, Want to Exit
Travelers transiting through Tan Son Nhat (SGN) or Noi Bai (HAN) who want to exit the airport and enter Vietnam need a valid eVisa or must be visa-exempt. The transit zone allows airside transit without a visa for most nationalities for up to 24 hours.
| Situation | Visa needed to exit airport? | Action |
|---|---|---|
| UK / FR / DE / KR / JP passport | No — 45-day exempt | Go through immigration directly. No eVisa needed. |
| ASEAN passport | No — 30-day exempt | Go through immigration directly. No eVisa needed. |
| US / CA / AU / IN passport | Yes — eVisa required | WhatsApp for priority eVisa. Entry port = SGN or HAN (wherever you are now). |
| Airside transit only (not exiting) | No — up to 24h airside | Stay in international transit zone. No visa required for onward connection. |
Transit eVisa Processing — What to Expect
| Time before Vietnam check-in closes | Option | Price | Available |
|---|---|---|---|
| 3+ hours, before 13:00 GMT+7 | 5-Hour eVisa — full approval before boarding | USD 125 | Weekday |
| 1–3 hours, before 15:00 GMT+7 | 2.5-Hour eVisa — approved at gate | USD 155 | Weekday |
| Under 1 hour, before 18:00 GMT+7 | 1-Hour eVisa or 30-60 min | USD 185–215 | Weekday |
| Any time, any day | Boarding Letter ~30 min — accepted at check-in supervisor | 24/7 |
At the transit airport — present Boarding Letter to the check-in supervisor, not the counter agent.
Counter agents often cannot override without supervisor approval. Ask specifically for the supervisor. Show the Boarding Letter on your phone screen. The full eVisa PDF will be delivered before the plane lands in Vietnam.
