If you are a Thai passport holder planning a trip to Vietnam, understanding vietnam visa for thailand passport requirements is the first step to avoid confusion and delays. Vietnam offers visa exemptions and visa options depending on the purpose and length of your stay. In this guide, we will explain the Vietnam visa rules for Thai citizens. We will do this clearly and simply, so you can prepare for your trip with confidence.

Do Thai citizens need a Vietnam visa?
The first thing to address is whether a Vietnam visa for Thailand passport is mandatory for all trips. The answer depends entirely on the duration and purpose of your stay.

Vietnam visa exemption for Thai nationals 30 days
Thailand is on the list of countries with a bilateral visa exemption agreement with Vietnam.
No visa required for Thai citizens 30 days: Thai citizens carrying a valid ordinary passport are exempt from Vietnam visa requirements for a stay of up to 30 days.
To qualify for this exemption, you must ensure:
- Your Thai passport has at least 6 months of validity remaining from the date of entry.
- You have a return ticket or a ticket to a third country.
- You are not on the list of individuals prohibited from entering Vietnam by the Vietnam Immigration Department.
This is perfect for short vacations or brief business trips. However, if your itinerary exceeds 30 days, or if you plan to work in Vietnam, you must apply for a visa.
Is a Thai passport exempt from the Vietnam visa for 30 days for re-entry?
Previously, there was a regulation requiring a gap of 30 days between two visa-free entries. However, under the new Law on Entry, Exit, Transit, and Residence of Foreigners in Vietnam (updated in recent years and valid in 2025), this restriction has been removed. Thai citizens can exit and re-enter Vietnam using the exemption status immediately, provided they still meet the requirements.
However, if you wish to stay longer than the exempted period without leaving the country, obtaining a visa for Vietnam from Thailand in advance is highly recommended.
Common types of Vietnam visas for Thai citizens
If the 30-day exemption does not cover your needs, you will need to apply for a visa. Here are the most common types of Vietnam visa for Thailand passport holders:

- Tourist Visa (DL): This is the most popular type for travelers who want to explore Vietnam for more than 30 days. Currently, the Vietnam e-Visa allows for stays of up to 90 days (single or multiple entries), which is a significant improvement for tourists wanting a long holiday.
- Business Visa (DN1, DN2): This applies to Thai citizens entering Vietnam to work with Vietnamese enterprises, attend conferences, or sign contracts. While an e-visa can be used for business purposes, longer-term business visas may require sponsorship from a company in Vietnam.
- Investment Visa (DT): Designed for foreign investors who contribute capital to businesses in Vietnam. The duration and validity depend on the value of the investment.
- Family Visit Visa (TT): Issued to foreigners who are spouses or children of Vietnamese citizens, or spouses/children of foreigners holding valid temporary residence cards in Vietnam.

- Correct Port of Entry: For E-visas, you must enter via the checkpoint listed on your visa. If you change your flight from landing in Hanoi to Ho Chi Minh City, your E-visa might not be accepted if it specifically states Hanoi.
- Land Border Crossings: If you plan to travel from Thailand to Vietnam via Laos or Cambodia by bus (Land border), the E-visa is valid. However, Visa on Arrival is not valid at land borders. You must have your visa (E-visa or Embassy visa) ready before you reach the border.
