Vietnam to Require Health Declarations for Inbound, Outbound and Transit Travelers from July 1, 2026

As of 1 July 2026, every person crossing a Vietnamese border gate — arriving, departing, or transiting — must complete a health declaration before they pass through. The requirement is not a temporary pandemic measure. It is a permanent obligation under Government Decree No. 165/2026/NĐ-CP, signed 15 May 2026 and implementing Vietnam's new Law on Prevention and Control of Infectious Diseases. For travelers planning extended journeys through Vietnam and the wider region, this adds a recurring administrative step to every border crossing. Understanding the rules now, before the system goes live, is the practical thing to do.

What the Rule Requires

Decree 165 is direct in its scope. All individuals entering, exiting, or transiting through Vietnam's border gates must submit a health declaration within seven days before their crossing. The rule applies regardless of nationality, visa category, or purpose of travel.

That means foreign tourists, Vietnamese citizens returning home, expatriate residents re-entering after a trip, and transit passengers who never formally clear immigration are all covered. Children and minors are included; a parent or guardian completes the form on their behalf and keeps it with the child's travel documents.

The declaration covers personal identification, contact details, transport information (flight number, vessel, or vehicle), recent travel history across a specified look-back period, and a health and symptom disclosure. Depending on global disease conditions, the Ministry of Health may also request proof of vaccination — yellow fever certificates for travelers from endemic regions, for example — though this is not expected to apply to most visitors under normal circumstances.

The form follows a standardised template, Appendix V of Decree 165. The Ministry of Health may update its content during specific disease events, so travelers should always retrieve the current version from official channels before each trip.

How and When to Submit

Decree 165 permits two submission routes: electronic and paper.

The electronic route is preferred. Travelers submit via an online portal designated by the Ministry of Health and receive a digital confirmation — likely a QR code or reference number — to present at health-quarantine counters at the border gate. The paper route remains available for those unable to submit online, either by printing the form in advance or completing it at health-quarantine counters on arrival or departure.

The seven-day window is fixed. A declaration submitted more than seven days before your crossing will be treated as invalid, and you will need to file again. Most travel advisors recommend completing the form one to three days before departure — close enough to reflect your actual health status, well within the legal window.

One important caveat: as of late June 2026, the Ministry of Health had not yet publicly announced the official portal address or app. The platform is expected to go live close to 1 July. Until then, travelers should monitor the Ministry of Health and Government Portal channels directly and avoid unofficial third-party declaration sites, several of which have already appeared online.

The Legal Basis and Who Enforces It

The Government — at cabinet level — issued Decree 165 to implement the new Law on Prevention and Control of Infectious Diseases, which enters into force on the same date. The Ministry of Health designs the declaration form, operates the digital platform, and retains authority to adjust the scope, content, and duration of specific requirements based on disease-risk assessment.

Border-control agencies — immigration, public security, customs — are responsible for integrating the requirement into entry and exit flows. Vialto Partners, a global mobility firm that issued a regulatory alert on Decree 165, notes that travelers who arrive without a completed form may be directed to submit one on the spot before proceeding, causing delays. In more serious cases — false declarations, refusal to provide information, or non-cooperation with health measures — travelers may be denied entry or exit under Vietnam's infectious-disease and immigration laws. Administrative fines also apply under existing health-quarantine violation frameworks.

For most healthy travelers who simply comply, the practical consequence of non-compliance is time: additional queues, paperwork at the counter, and the risk of missed connections.

What This Means for Slow Travelers

For visitors spending weeks or months in Vietnam — with side trips to Laos, Cambodia, or elsewhere in the region — the seven-day validity window has a direct implication: every border crossing is a separate event requiring a fresh declaration.

A traveler on a two-month itinerary that moves Vietnam → Laos → Vietnam → Cambodia → Vietnam → home could easily need four to six separate declarations over the course of one journey. This is not a one-time registration. It is a recurring compliance step, closer in nature to Advance Passenger Information than to a visa application.

Overland routes and remote land or river crossings deserve particular attention. Digital infrastructure at smaller border gates — especially those connecting with Laos and Cambodia — is likely to lag behind major airports in Hanoi and Ho Chi Minh City during the early months of implementation. Carrying a printed paper copy of your declaration is sensible practice at any crossing, essential at remote ones.

Build extra time into border-crossing plans. Travel advisors suggest at least thirty to sixty additional minutes, particularly in the first months of the system's operation. For same-day transit connections, that buffer matters.

Vaccination records — COVID-19, yellow fever, influenza — are worth keeping accessible in both digital and paper form, even if they are not routinely checked. If a declaration or on-site screening flags a concern, having documentation to hand moves things along. Travel health insurance that explicitly covers quarantine, medical evaluation, and trip disruption caused by health-quarantine orders becomes more relevant under this framework.

Is This a Return to COVID-Era Controls?

The comparison is understandable but imprecise. During the pandemic, Vietnam operated a temporary electronic declaration system — the Vietnam Health Declaration app and later PC-COVID — under emergency decisions tied to a single pathogen. Those measures were wound down as Vietnam reopened in 2022.

Decree 165 is structurally different. It is a permanent implementing decree under a general infectious-disease law, designed to apply across multiple possible outbreaks — influenza, COVID variants, Ebola, yellow fever — rather than one. The Ministry of Health retains discretion to tighten or relax specific requirements as the disease landscape changes. Some form of health declaration at Vietnam's borders may now be a long-term feature of entry and exit, not a temporary response to a single crisis.

The practice is familiar. The legal foundation is new.

Frequently Asked Questions

Does this apply to Vietnamese citizens, or only foreign visitors?

It applies to everyone. Decree 165 covers all individuals crossing Vietnamese border gates, with no exemption by nationality. Vietnamese citizens departing or returning home must complete the declaration, as must foreign tourists, expatriate residents, work-permit holders, and students. The seven-day window and submission requirements are identical for all travelers regardless of passport.

Do transit passengers need to file a declaration?

Yes. The regulation explicitly includes transit through Vietnamese border gates. Even passengers who remain airside and never clear immigration are covered. If your itinerary routes you through a Vietnamese airport or seaport in transit, you must complete a health declaration within seven days before that crossing, the same as any arriving or departing traveler.

Where do I find the official form or portal?

As of late June 2026, the Ministry of Health had not yet published the official portal address. The platform is expected to launch close to 1 July 2026. Monitor the Ministry of Health website and Vietnam's Government Portal directly. Do not use unofficial third-party declaration sites — several have appeared online and are not authorised. Paper forms will also be available at health-quarantine counters at border gates.

Will I need to show proof of vaccination?

For most travelers under normal conditions, no. Vaccination proof is a conditional requirement under Decree 165, triggered by specific disease-risk assessments — for example, yellow fever certificates for travelers arriving from endemic countries. Routine absence of vaccination records is unlikely to block entry. However, the Ministry of Health can expand documentation requirements during outbreaks, so travelers from higher-risk regions should check current MOH guidance before each trip.

What happens if I don't complete the declaration before I arrive?

You will be directed to complete a paper form at the health-quarantine counter before you can proceed. This adds time and, at busy airports, can mean a significant queue. If you refuse to provide required information or submit a false declaration, you risk denial of entry or exit and potential administrative fines under Vietnam's health-quarantine violation framework. For most travelers, the real cost of non-compliance is delay.

How long will this requirement stay in place?

No end date is specified. Decree 165 is a permanent implementing decree under Vietnam's general infectious-disease law. The Ministry of Health determines the scope and duration of specific requirements based on ongoing disease-risk assessment. Some form of health declaration at Vietnam's borders is likely to remain in place indefinitely, though the questions asked and documentation required may tighten or relax depending on the public health situation at any given time.

I'm planning a multi-month trip with several border crossings. Do I file once or each time?

Each time. The declaration is specific to each border crossing and valid only within the seven-day window before that crossing. A two-month itinerary involving multiple entries and exits through Vietnam will require a separate declaration for each one. Travelers making frequent border movements should build this into their planning — a reminder set two to three days before each crossing is a practical habit to develop.
