Vietnam E-Visa Explained: 90-Day Stays, Entries & Overstay Risk

Who needs to read this

Vietnam's e-visa became one of Asia's most flexible tourist entries in 2023, but its mechanics, validity windows, designated ports, and the near-absence of in-country extensions, still catch travelers out. Read this if:

• You're a tourist from anywhere: the scheme is open to citizens of all countries and territories
• You're a digital nomad planning a long Vietnam base on 90-day windows
• You're combining Vietnam with neighbors and need entries and exits to line up with the designated-port list
• You're choosing between single and multiple entry and unsure how the windows work
• You're near the end of a stay and wondering whether an extension exists (mostly, it does not)

How the rule works

Vietnam grants electronic visas for stays of up to 90 days, single or multiple entry, to applicants from all countries, under the Law on Foreigners' Entry Into, Exit From, Transit Through and Residence in Vietnam (Law No. 47/2014/QH13, as amended in 2023, when the National Assembly lengthened the e-visa maximum from 30 to 90 days and opened it worldwide). The essentials, per the official immigration portal:

• You choose your dates and entry type when applying; what is granted is a validity window of up to 90 days, single or multiple entry.
• Applications are online only at evisa.gov.vn, with a processing standard of about three working days and fees paid electronically (the published rates are USD 25 single entry, USD 50 multiple entry).
• Your passport needs at least six months validity, and you must not fall into the entry-suspension cases in Article 21 of the immigration law.
• Designated ports only: the e-visa works at the airports, land crossings, and seaports on the official published list.
• The fee is not refunded if the application is refused, and each traveler (children included) needs their own e-visa.

Counting the days

The e-visa gives you a dated window, and every day inside Vietnam within that window counts, arrival and departure days included. The mechanics:

• The window is fixed at grant. Request 1 March to 29 May and those dates are the visa. Enter on 1 April and you still must leave by 29 May; the unused month is simply lost.
• Single entry: one entry, and departure ends the visa even if days remain.
• Multiple entry: come and go freely inside the window; days outside Vietnam are not Vietnam days, but the window keeps running regardless.
• Worked example: on a 90-day multiple-entry e-visa from 1 March, you spend March in Hanoi, April in Bangkok, and return 1 May. Your remaining time runs only to the window's end in late May; the Bangkok month did not pause anything.
• The stamp still matters. Officers record your entry against the visa; keep the printed e-visa with you at entry and exit.

Resets, extensions, and edge cases

A new e-visa resets everything, and that is the standard playbook, because in-country extensions are the exception. The edge cases:

• No routine extension. The official position: an e-visa holder in Vietnam may be considered for a new visa if invited or guaranteed by an authority, organization, or individual in Vietnam. Without a sponsor, the route is exit, reapply, re-enter.
• Back-to-back e-visas are common practice: leave (Bangkok, Phnom Penh, or a land crossing on the list), hold approval for the next window, return. Each application is a fresh decision; refusals happen and the fee is sunk.
• Match ports to the list in both directions. The designated-port list covers the major international gateways, but remote land crossings may not qualify.
• Different rules for some nationalities: Vietnam separately grants unilateral visa-free entry (typically 45 days) to a set of countries, and those travelers only need the e-visa for longer stays. Check whether your passport has a visa-free allowance before paying for a window you do not need.
• Work is out of scope. The e-visa is for tourism, visits, and business activities that do not amount to working in Vietnam; employment needs a work permit and the corresponding visa or residence card.

Overstays: consequences and enforcement

Overstaying a Vietnamese visa is an administrative violation with escalating fines, and it blocks your departure until resolved. What to expect:

• Fines scale with the overstay length under Vietnam's administrative-penalty rules for immigration violations (Decree 144/2021/ND-CP); short overstays are fined modestly, long ones severely.
• Departure requires clearance. You settle the violation with immigration before exit, which for anything beyond a trivial overstay means an office visit, payment, and documentation, not just a counter payment at the gate.
• Serious cases escalate to deportation and entry bans, and an overstay record complicates future Vietnamese visa applications.
• Detection is structural: entry and exit records are electronic, hotels and landlords must register foreign guests' temporary residence, and the exit check reconciles your stay against the visa window.

Staying compliant

The e-visa's flexibility is real, but it rewards people who manage the window, not the vibe:

• Anchor on the validity end date, not "90 days from when I landed." Enter mid-window and your stay is shorter than 90 days by definition.
• Track your days and window together. iReside's Vietnam e-Visa preset counts your days in-country from your location and shows time remaining on the window, so the reapply-or-leave decision surfaces early.
• Plan the next visa before day 80. Approval takes days, refusal is possible, and border-run logistics need a valid approval letter in hand.
• Check the designated-port list every trip; itineraries through minor crossings are where e-visas fail.
• Keep printed copies of the e-visa and entry stamp pages; temporary-residence registration by your hotel or landlord is their duty, but carrying your own paperwork keeps checks short.

Common mistakes

• Treating the 90 days as starting at entry. The window starts on the validity start date you requested; late entry shortens the trip.
• Buying single entry for a multi-country itinerary. One side trip to Angkor or Luang Prabang ends a single-entry visa; the multiple-entry version exists for exactly this.
• Assuming an extension office will fix it. Routine in-country extension of e-visas is not part of the current scheme; the sponsored new-visa route is narrow and not a tourist tool.
• Entering at a port that is not on the list. The visa is only usable at designated checkpoints, and airlines and border officers apply the list literally.
• Ignoring the visa-free overlap. Nationals of countries with 45-day visa-free entry sometimes buy an e-visa they did not need, or worse, mix up which regime their current stay is under and miscount the deadline.
• Letting the exit day slip past the window. Both the overstay fine and the departure-clearance process start the next morning; the window's end date is the real end of the trip.
