Vietnam E-Visa: Why 90 Days Is a Window, Not a Count of Your Days
Quinn Moran · Published
A Vietnam e-visa covers up to 90 days, but those 90 days are a fixed validity window set when the visa is granted. They are not a count that starts when you land. Entering late shortens the stay, and on a multiple-entry e-visa the window keeps running while you are outside Vietnam. Arrival and departure days both count as days inside Vietnam.

Most visa rules give you a number of days and count down as you use them. Vietnam's e-visa works the other way round. The 90 days are not an allowance you spend. They are the upper limit on a dated window that is fixed when the visa is granted. Every detail of how days count against it follows from that, and most Vietnam stays that get miscounted were treated as a balance when they were really a window.
This post covers the counting: what the window is, what late entry does to it, what a departure does on single and multiple entry, and where arrival and departure days fall. The full rule is in the Vietnam e-visa guide, including who can apply, the designated ports and the overstay regime.
The 90 days are a ceiling on the window
Since August 2023, Vietnam has issued e-visas to citizens of all countries and territories. The maximum stay went from 30 to 90 days at the same time. The legal basis is the Law on Foreigners' Entry Into, Exit From, Transit Through and Residence in Vietnam (Law No. 47/2014/QH13), as amended in 2023.
The applicant picks dates and an entry type in the online application. What comes back is a validity window of up to 90 days, single or multiple entry. The window has a start date and an end date, and those two dates are the visa. Nothing after the grant moves them.
That makes it a different kind of rule from a per-entry clock, where the count starts at the border. On a Vietnam e-visa, crossing the border starts nothing. The calendar began on the validity start date, whether or not you were in the country yet.
Two numbers that look the same and are not
A Vietnam e-visa produces two figures, and they match in only one case.
| What it measures | Set by | Runs while you are abroad? | |
|---|---|---|---|
| Validity window | Calendar span from start date to end date, up to 90 days | The grant | Yes |
| Days in Vietnam | Calendar days physically in the country inside that window | Where you actually were | No |
The two are equal only when someone enters on the start date, never leaves and exits on the end date. A late entry, or any trip out on a multiple-entry visa, opens a gap between them.
The visa's limit comes from the first figure. The second is the one people remember and quote. Counting days in Vietnam and comparing the total with 90 answers a question the visa never asks.
Late entry: the unused days are gone
The guide's own example shows it best. Take a requested window of 1 March to 29 May, which is 90 days counting both ends. Enter on 1 April and the deadline is still 29 May.
| Window | Entry date | Last permitted day | Days available |
|---|---|---|---|
| 1 March to 29 May | 1 March | 29 May | 90 |
| 1 March to 29 May | 1 April | 29 May | 59 |
The March days were not saved for later. They expired. Nothing in the scheme moves the window to match the entry date, and there is no routine way to recover the lost month once you are in the country.
The usual phrase, '90 days from when I landed', describes a rule Vietnam does not have. The real deadline is the end date on the visa, and a stay that starts mid-window is shorter than 90 days by definition.
Single entry: the first departure ends it
A single-entry e-visa allows one entry. Departure ends the visa even if days remain in the window. The guide gives a side trip to Angkor or Luang Prabang as the typical case. A few days away does not pause a single-entry e-visa. It ends it, and coming back needs a new visa.
So a single-entry e-visa covers at most one unbroken block of Vietnam days. A day record showing Vietnam, then another country, then Vietnam again cannot all sit under one single-entry visa. The second block belongs to a different document.
Multiple entry: the window does not pause
Multiple entry lets you come and go as often as you like until the validity end date. Days outside Vietnam are not Vietnam days. The window keeps running anyway.
Here is the guide's example worked through. A 90-day multiple-entry e-visa starts on 1 March, so the window ends on 29 May. The holder spends March in Hanoi and exits on 31 March, spends April in Bangkok, and comes back on 1 May.
| Period | Where | Vietnam days | Window days elapsed |
|---|---|---|---|
| 1 to 31 March | Vietnam | 31 | 31 |
| 1 to 30 April | Thailand | 0 | 30 |
| 1 to 29 May | Vietnam | 29 | 29 |
| Total | 60 | 90 |
That is 60 days in Vietnam, and the visa has run out. The Bangkok month did not pause anything. It used up a third of the window without adding a single Vietnam day.
The neighbouring countries keep their own counts as well. The Thailand visa exemption is per entry, and the Indonesia visa on arrival runs its own clock. In the example above, April sits on two records at once. It counts as Thailand days under Thai rules and as elapsed days on the Vietnamese window. One calendar month, two rules, each using it differently.
Arrival and departure days both count
In a day-by-day record, the day you clear entry and the day you exit are both Vietnam days, even though you were only there for part of each. On a multiple-entry visa, each trip out creates an exit day and a re-entry day, and both are Vietnam days.
The end date is a hard deadline for the exit day. The guide spells out the edge: both the overstay fine and the departure-clearance process start the morning after the window ends. A late entry gives no extra time past the end date.
When the window runs out
In-country extension is the exception. An e-visa holder in Vietnam may be considered for a new visa if invited or guaranteed by an authority, organisation or individual in Vietnam. That is a sponsored application, not a routine extension. Without a sponsor, the usual pattern is to exit, apply for a fresh e-visa and re-enter.
A new e-visa resets everything: a new window with its own start and end dates. Back-to-back e-visas are common practice. But each application is a separate decision, refusals happen, and the fee is lost if the application is refused. Entries are also limited to the ports on the official designated-port list, which covers major airports, land crossings and seaports. Remote land crossings may not be on it.
Past the end date, the stay becomes an overstay. That is an administrative violation under Decree 144/2021/ND-CP, with fines that rise with the length of the overstay. The violation has to be settled with immigration before you can leave. For anything beyond a trivial overstay, that means an office visit, payment and paperwork, not a quick payment at the gate. Serious cases can lead to deportation and entry bans.
Detection is built into the system. Entry and exit records are electronic, hotels and landlords must register foreign guests' temporary residence, and the exit check compares the stay with the visa window. Whether the window held is decided at the border, against dates already on file.
Which document is the current stay under
Some passports are on Vietnam's unilateral visa-free list, which typically grants 45 days. Those travellers only need the e-visa for longer stays. The guide names the counting problem this creates: losing track of which regime the current stay falls under, and then counting against the wrong deadline.
A visa-free stay and an e-visa stay are different rules with different limits. The day count is the same either way, because days in Vietnam are days in Vietnam. The deadline it is compared with depends on which document the entry was made on. A record of days answers the first question. The visa answers the second.
The e-visa covers tourism, visits and business activities that do not amount to working in Vietnam. Employment needs a work permit and the matching visa or residence card. Whether a particular activity is allowed is not a day-count question, and no tally of days settles it.
What a day record can and cannot show
A day-by-day record handles the Vietnam days column well. iReside records which country you were in on each calendar day, from your iPhone's location, in the background. Day counts for each rule you track are worked out from that record continuously, so the number builds up as you live rather than being pieced together after the fact. iReside's Vietnam e-visa tracker counts the days of each visit against 90; it does not read the window's end date from your visa, so check the end date printed on the e-visa yourself.
The record can be exported as CSV or PDF. Each day is labelled with where it came from: GPS, manual entry, or a planned future day. In the multiple-entry example above, the export would show 31 March as a Vietnam day, every April day as Thailand, and 1 May as Vietnam again. That is the second column of the table, with no gaps to fill in from memory.
The window comes from the visa, not from your location. Its start and end dates are printed on the e-visa, and whether you are inside them is a comparison between those dates and the record. More on how day records work across visa rules is on the visa tracking page. The rule those days are counted against, including ports, the visa-free overlap and overstays, is set out in full in the Vietnam e-visa guide.
