Vietnam, Then Cambodia, Then Back to Vietnam: What Visa Setup You Actually Need
Direct Answer
If your itinerary leaves Vietnam and comes back — for a side trip to Cambodia, Laos, or anywhere else — you need a multiple-entry Vietnam e-visa, selected when you apply, for an additional $25. A single-entry visa only covers your first entry and can't be upgraded afterward, so getting this right before you apply matters more than almost anything else on a multi-country trip.
Southeast Asia trip planning often means crossing in and out of Vietnam more than once — here's exactly what that requires.
The One Decision That Matters Most: Single vs. Multiple-Entry
| Your Itinerary | What You Need |
|---|---|
| Enter Vietnam once, stay the whole trip | Single-entry (standard price) |
| Vietnam → Cambodia/Laos → Vietnam | Multiple-entry (+$25) |
| Vietnam → Thailand → Vietnam | Multiple-entry (+$25) |
| Not sure yet if you'll leave and return | Choose multiple-entry to be safe — cheaper than reapplying later |
Why This Can't Be Fixed After the Fact
Single-entry can't be upgraded to multiple-entry after you've applied. If you selected single-entry and then realize mid-trip you need to leave and come back, the fix is a brand new application, not an amendment to the existing one — plan this before you apply, not after you've already left Vietnam for your side trip.
Your Vietnam Visa Doesn't Cover Cambodia or Laos
This sounds obvious written out, but it trips people up in practice: your Vietnam e-visa only handles Vietnam entry and re-entry. Cambodia and Laos each have their own separate visa requirements and application processes — check those independently for your specific nationality before you travel.
Does the Validity Period Cover Both Entries?
Yes, as long as both entries fall within your visa's validity window — 30 or 90 days from approval, your choice at the same price. Leaving and re-entering doesn't "use up" validity faster; it's purely calendar-based. If your side trip is short and well within your validity window, this generally isn't something to worry about.
If You Only Realize You Need This Mid-Trip
It happens — plans change once you're already traveling. The fix: apply for a fresh multiple-entry e-visa before you actually leave Vietnam for your side trip. This can be done entirely online, including from within Vietnam itself, so a change of plans mid-trip doesn't have to derail things — it just means an extra application.

Frequently Asked Questions
I'm going Vietnam, then Cambodia, then back to Vietnam. What visa do I need?
A multiple-entry Vietnam e-visa, selected at the time you apply — an additional $25 on top of the base fee. A single-entry visa only covers your first entry and can't be used to re-enter.
Can I upgrade a single-entry visa to multiple-entry after I've already applied?
No — this needs to be selected at the time of the original application. If you already applied for single-entry and realize you need multiple-entry, you'll need a new application.
Does my Vietnam visa's validity period cover the whole multi-country trip?
As long as both your entries into Vietnam fall within the visa's validity window (30 or 90 days), yes — the validity period isn't used up by leaving and re-entering, only by the calendar dates involved.
Do I need a different visa for Cambodia or Laos while I'm there?
Yes — your Vietnam visa only covers Vietnam. Cambodia and Laos have their own separate entry requirements, which you'll need to check independently.
What if I only realize I need multiple-entry after I've already left home?
Apply for a fresh multiple-entry e-visa before you leave Vietnam the first time — this can be done online from anywhere, including from within Vietnam itself before your side trip.
