As Vietnam’s economy continues to grow rapidly, an increasing number of Thai companies are expanding their operations, establishing bases, and exploring new markets in the country. Whether you are flying from Bangkok to Ho Chi Minh City for a business meeting, inspecting supply chains in Bac Ninh or Binh Duong, or traveling to Hanoi to sign a cooperation contract, securing a legal and compliant business visa is a crucial step that should not be overlooked.
As of 2026, Thai passport holders traveling to Vietnam for tourism or short-term business enjoy a 30-day visa-free entry. However, a Business E-Visa offers a maximum stay of up to 90 days with options for single or multiple entries, making it far more flexible than the 30-day visa exemption. Below is a comprehensive guide to the visa types, required documents, application procedures, and latest policy updates for Thai citizens applying for a Vietnam business visa in 2026-2027.
I. Core Knowledge Before Thai Citizens Apply for a Vietnam Business Visa
📌 What is the difference between the 30-day visa exemption and a business visa for Thai passports? Thailand is one of the ASEAN member countries on Vietnam’s unilateral visa exemption list. However, the visa exemption applies only under the following conditions:
- Stays not exceeding 30 days
- Single entry
- Not applicable for official employment or long-term business activities
If your business itinerary meets any of the following conditions, you must apply for a visa in advance:
- Stays exceeding 30 days
- Multiple entries and exits required
- Engaging in official work, investments, or long-term projects
⚠️ Important Reminder: Entering Vietnam under the 30-day visa exemption for official business negotiations or contract signings may sometimes go unquestioned for brief trips, but engaging in formal work or long-term activities can still be deemed a violation. To ensure a seamless trip, it is strongly recommended to apply directly for a Business E-Visa.

V. Important Notices (Must Read Carefully)
⚠️ Do Not Confuse Business Visas with Visa Exemptions While Thai passports enjoy a 30-day visa exemption, this exemption does not cover formal employment or long-term business activities. If your business trip exceeds 30 days or requires multiple entries, you must apply for a business visa in advance.
⚠️ Passport Information Must Be 100% Accurate Vietnamese customs enforce a strict 100% accuracy rule for E-Visa data. Even if a first and last name order is accidentally reversed, airlines will often refuse to issue a boarding pass. If errors are found after issuance, you must reapply and pay the fee again.
⚠️ Electronic Visas Cannot Be Extended Inside the Country Business E-Visas cannot be extended while inside Vietnam. If you need to prolong your stay, you must leave the country and reapply.
⚠️ Apply in Advance It is recommended to apply at least one to two weeks in advance to avoid travel disruptions caused by review delays.
⚠️ Port of Entry Cannot Be Changed Once an E-Visa is issued, the port of entry cannot be altered. Please double-check your initial entry airport or border gate when applying.
⚠️ Special Regulations for Phu Quoc Thai passport holders traveling to Phu Quoc Island also enjoy a 30-day visa exemption under the same conditions as mainland Vietnam—passport validity of at least 6 months and a return flight ticket. If you plan to visit other Vietnamese cities, a visa must still be obtained.
