Vietnam has introduced a new mandatory health declaration requirement for all international travelers, effective July 1, 2026. Under the new regulation, anyone entering, leaving, or transiting through Vietnam must complete a health declaration within seven days before their travel date, regardless of nationality or the purpose of their trip.
The requirement applies broadly, covering not just travelers arriving in Vietnam for tourism or business, but also those departing the country and those simply transiting through Vietnamese airports on their way elsewhere. Vietnamese authorities have framed the measure as part of a wider government effort aimed at monitoring infectious disease risks connected to international travel.
Alongside the health declaration rule, Vietnam has also rolled out two new visa categories, designated UĐ1 and UĐ2, which took effect on the same date. These categories are intended for a specific group of foreign professionals and their accompanying family members, though the health declaration requirement itself applies far more broadly to the general traveling public.
Health declaration requirements of this kind have become an increasingly common tool used by governments across Southeast Asia to track and manage disease risks tied to cross-border movement. Vietnam's decision to apply the rule to all travelers, rather than limiting it to arrivals from specific regions, marks a notably comprehensive approach compared to more narrowly targeted health screening measures used elsewhere.
Because the declaration must be completed within a defined seven-day window before travel, timing matters. Travelers who complete the form too early, before the seven-day window opens, or who forget to complete it altogether, could face complications either at check-in or upon arrival, departure, or transit through Vietnamese airports.
What this means for you
If your travel plans involve entering, leaving, or simply connecting through Vietnam, you will need to complete the required health declaration within seven days of your travel date, regardless of how brief your stay or connection may be. This applies even if Vietnam is not your final destination, so travelers using Vietnamese airports purely for transit purposes should not assume they are exempt.
Check the official Vietnamese government or health ministry channels for the correct declaration form and process well before your trip, and keep a copy of your confirmation to present if requested by airline staff or immigration officials. Building in extra time before departure to complete this step is a sensible precaution given the new rule's broad scope.
Given how recently this requirement took effect, travelers booking last-minute trips to, from, or through Vietnam should treat the health declaration as a mandatory pre-flight checklist item, alongside passport and visa checks, rather than an optional formality.
