Starting April 15, 2026, you must submit a new document before landing. The vietnam pre arrival form thailand requirement applies to all foreign visitors. This specifically includes Thai passport holders arriving at Tan Son Nhat International Airport (SGN).

This guide explains exactly how to complete this mandatory process online. You will learn about visa exemption rules, the exact application steps, and common errors. Follow these instructions carefully to ensure a smooth entry into Vietnam.

Do Thai Citizens Need It?

Yes, Thai citizens must complete this digital document before traveling. The Vietnam Immigration Department requires it for all foreign passport holders entering the country. The rule became officially mandatory on April 15, 2026.

You only need to fill this out if you fly into Tan Son Nhat Airport (SGN). SGN is the main international airport located in Ho Chi Minh City. If you land in Hanoi (HAN) or Da Nang (DAD), you do not need it yet.

You must submit your personal details up to three days before your arrival date. This 72-hour window is strictly enforced by the portal system. The official government portal is completely free to use for all travelers.

Do not pay any third-party service fees to complete this simple requirement. It takes only a few minutes to finish the process yourself.

Thailand–Vietnam Bilateral Exemption

Thai passport holders enjoy special travel privileges when visiting neighboring Vietnam. Thailand and Vietnam share a generous bilateral visa exemption agreement. This specific treaty allows Thai citizens to stay in Vietnam for up to 30 days visa-free.

When you fill out the digital document, you must indicate your exact visa status. In the visa section, carefully choose "Bilateral exemption" from the dropdown menu. This correctly matches your Thai passport benefits with the immigration database.

You will also need to select passport type "P" for a standard Thai passport. Make sure your physical passport is valid for at least six months. The six-month validity must be counted from your exact arrival date at SGN.

Meeting these passport requirements ensures your bilateral exemption remains valid upon entry. Immigration officers will check this data against your submitted online form.

Step-by-Step from Bangkok (BKK or DMK)

Flying from Bangkok to Ho Chi Minh City is a very simple process. Major carriers like Thai Airways (TG) and AirAsia Thailand (FD) operate multiple daily flights. Bangkok Airways (PG) and VietJet (VZ) also frequently fly this busy Southeast Asian route.

You must submit your information online before boarding your flight at Suvarnabhumi (BKK) or Don Mueang (DMK). First, visit the official government website at prearrival.immigration.gov.vn. Start your application by selecting "Thailand" as your nationality.

Next, enter your detailed passenger information into the system. You must include your +66 country code and your exact passport details. Double-check your passport numbers to avoid any typing errors.

Then, you must provide your specific trip information to the authorities. Enter your exact airline flight code and your full hotel address in Ho Chi Minh City. Finally, review all your details carefully and submit the application.

If you travel with family members, the process is slightly faster. Use the handy "Add Passenger +" button located in Step 2. This links your family together on a single submission record.

Common Mistakes

Many travelers make small formatting errors that cause big delays at the airport. A very frequent mistake is selecting the wrong destination airport. This requirement is exclusively for Tan Son Nhat (SGN) in Ho Chi Minh City.

Another common error involves complicated transit flights. Many Thai citizens transit through Bangkok from other international countries. Pay close attention to the departure country field so it reflects your actual origin.

Additionally, you must ensure your accommodation address is highly specific. You must list the province, city, ward, commune, and exact street address. Simple answers like "a hotel in Ho Chi Minh City" are strictly rejected.
