Vietnam Visa / E-visa for Thai Citizens 2025: Guide, Fees & Requirements

Lượt xem: 16

Thai citizens enjoy visa-free entry to Vietnam for up to 30 days for tourism or short business trips under a bilateral agreement. For stays longer than 30 days, multiple entries, or other purposes, a visa is required, such as a 90-day e-Visa, Visa on Arrival, or Embassy visa. Travelers must ensure their passport is valid for at least 6 months with two blank pages. Always choose the visa type that matches your length of stay and travel purpose.

Vietnam Visa Exemption for Thai Citizens

Thailand is one of the 25 countries eligible for Vietnam Visa Exemption for Thai travelers ^[1] Under this agreement, Thai citizens may enter Vietnam for up to 30 days without a visa for tourism or short business activities.

To benefit from the 30-day visa free Vietnam policy, travelers must present a valid Thai passport and meet standard entry conditions.

Conditions for Visa-Free Entry

Thai citizens may enter Vietnam visa-free if they meet:

• A Thai passport valid for at least 6 months beyond the arrival date
• At least 2 blank pages for entry/exit stamps
• No record of immigration violations in Vietnam
• A confirmed plan that does not exceed 30 days of stay
  

Most Thai travelers enter without needing to prepare anything ahead of time, but officers may occasionally ask for supporting documents depending on your travel purpose and profile.

When a visa is required

Although visa exemption is convenient, Thai travelers must apply for a visa if they plan to:

• Stay longer than 30 days
  
• Work or participate in employment-related activities
• Invest or join long-term projects
• Engage in journalism or media-work assignments

Vietnam offers multiple visa types – including tourist, business, and long-term e-visas – giving travelers flexible options depending on their plans.

Applying for a Longer Stay: Tourist Visa (DL) and Business Visa (DN) Options

When 30 days is not enough, Thai passport holders can apply for either:

• Tourist Visa (DL) – for travel, exploration, remote work, yoga retreats, wellness trips, or visiting friends
• Business Visa (DN) – for meetings, supplier visits, negotiations, market research, and business activities

In 2025, the 90-day Vietnam e-visa is the most preferred choice due to its simplicity and speed. Both single-entry and multiple-entry formats are available.

Vietnam E-Visa for Thai Citizens

The e-visa offers the greatest flexibility, allowing stays of up to 90 days.

► Requirements

• Valid Thai passport (6+ months remaining)
• A clear passport bio-page scan
• Vietnam visa photo (white background)
• Entry port selection (airports, land borders, or seaports)

► Government Fees & Validity ^[2]

► E-Visa Service Fees (Through Tân Văn Lang)

*Note: Fees may vary depending on timing and regulations. Please contact us for personalized consultation based on your specific case.

Visa on Arrival (VOA) for Thai Citizens

Although less popular than the e-visa, VOA is still available for air arrivals. Thai travelers must obtain a Vietnam visa approval letter before boarding the plane.

► VOA Fees (Service Fee Only – Stamp Fee Not Included)

Stamp fees at the airport must be paid separately (25 USD or 50 USD depending on entry type).

What happens if you overstay the 30-day Visa-Free limit?

Overstaying visa in Vietnam can lead to penalties, fines, delays, or complications for future entries. Thai citizens who exceed their permitted period may face:

• Fines ranging from 1,250,000 VND to 4,000,000 VND
• Possible future entry restrictions
• Difficulty boarding outbound flights without paying penalties
• A mandatory extension or exit visa before departure

Short overstays (1–3 days) can often be resolved quickly, but longer violations require more processing time with the Vietnam Immigration Department.

To avoid issues, apply for an extension at least 7–10 days before your exemption expires.
