Direct Answer
Singaporean citizens are visa-exempt. All other passport holders need a Vietnam eVisa before check-in at Changi. 1-Hour USD 185 before 19:00 SGT (18:00 VNT). 1-Day USD 110 before 12:00 SGT. SGT = VNT+1h.
Critical: SIN is never the entry port. The entry port must be the Vietnamese airport where the plane lands — SGN, HAN, DAD, PQC, or CXR. Entering SIN triggers silent Amendment Required with no email.

Vietnamese government pauses processing 13:00–14:30 SGT (12:00–13:30 VNT). If your check-in falls in this window: Boarding Letter issued immediately, visa completed after 14:30 SGT.

The SIN Entry Port Error — Most Common Mistake from Singapore
This is the single most common cause of Vietnam eVisa problems for travelers departing Singapore. SIN is the IATA code for Singapore Changi Airport. It is the departure point, not the entry point into Vietnam. The Vietnam eVisa entry port field asks for the Vietnamese airport where your plane will land — not where you are flying from.
The evisa.gov.vn portal accepts SIN in the entry port field without any warning or error message. The application looks successful. Immigration review catches the mismatch days later, triggers Amendment Required, and stops all processing — no email sent. By the time the traveler discovers this, the flight window may already have closed.
| Route from SIN | Wrong entry port | Correct entry port | Airlines |
|---|---|---|---|
| SIN → SGN (Ho Chi Minh City) | SIN | SGN | SQ, TR, VJ, VN, QH |
| SIN → HAN (Hanoi) | SIN | HAN | SQ, TR, VN |
| SIN → DAD (Da Nang) | SIN | DAD | VJ, VN, TR |
| SIN → PQC (Phu Quoc) | SIN | PQC | VJ, QH |
How to find the correct port: open booking confirmation → Vietnam-landing segment → "Arrives" column → that 3-letter IATA code = entry port.
Already submitted with SIN as entry port? Check status at evisa.gov.vn/e-visa/search with Reference Code. If Amendment Required: free correction via WhatsApp — SIN replaced with correct Vietnamese airport code and resubmitted priority. Do not reapply.
At Changi Airport Without a Visa
Airlines at Changi verify Vietnam visa documents at check-in using TIMATIC. No approved eVisa PDF or Boarding Letter means denied boarding at T1, T2, or T3 before the gate. If you are at Changi now and do not have an approved eVisa:
Step 1 — Do not queue at the check-in counter
Step aside and contact WhatsApp +84 947 754 252 immediately with: flight number + SGT departure time + passport nationality + Reference Code if already applied.
Step 2 — Receive Boarding Letter in ~30 minutes
Boarding Letter confirms the eVisa is registered in the Vietnamese immigration system and in priority processing. Available 24/7 — no SGT cutoff. Full approved eVisa PDF delivered before landing.
Step 3 — Present to check-in supervisor
Present Boarding Letter to the check-in supervisor, not the counter agent. SQ, TR, VJ, VN, QH, and other Vietnam-bound carriers at Changi accept it. State: "I have a Boarding Letter from my visa processing agency confirming my eVisa is in priority processing. Can I speak with the check-in supervisor?"

At Changi or past 19:00 SGT? Boarding Letter ~30 min • 24/7 • Accepted at T1, T2, T3 • Present to supervisor WhatsApp Boarding Letter → |
Already Applied — Speed Up Without Reapplying
If already submitted on evisa.gov.vn and the USD 25 government fee has been paid, check status at evisa.gov.vn/e-visa/search with Reference Code (format E260705...) and registered email.
| Approved | Download PDF. Verify: name vs passport MRZ, entry port (SGN/HAN/DAD not SIN), entry date = Vietnam arrival date. Save offline before boarding. |
| In Process | Speed Up via WhatsApp with Reference Code + registered email + flight number. USD 85 (1-Day) to USD 160 (1-Hour before 19:00 SGT). No new govt fee. |
| Amendment Required | Error stopped processing — almost certainly SIN entered as port instead of SGN/HAN. Free correction via WhatsApp. Corrected and resubmitted priority. Boarding Letter as bridge. Do not reapply. |
Do not reapply. Two applications with the same passport = 24–48h deduplication hold on both. Speed Up escalates the existing application, deducts the USD 25 already paid, and issues a Boarding Letter as bridge.
