Vietnam e-Visa for Thai Citizens 2026: 30-Day Visa Exemption vs e-Visa, Documents and Common Mistakes
Thai passport holders visiting Vietnam for tourism for up to 30 days are visa-exempt — no advance application is needed, only a passport valid for at least 6 months and an onward ticket. For a stay beyond exemption, check the appropriate e-Visa or other authorisation through the official Vietnam Immigration Department portal (evisa.gov.vn), which issues visas of up to 90 days in single or multiple entry form. Processing times vary, so apply in advance; an e-Visa does not guarantee entry.

Separate each arrival from the visa entry count
A single-entry e-Visa ends its entry entitlement when you leave. That does not prove you cannot qualify for visa exemption on a subsequent arrival. Before a side trip, check your passport, intended stay and immigration history with the Vietnamese authority instead of buying a multiple-entry document solely because an agent says all return visits require one.
The Immigration Department’s portal notice identifies two new official domains and a maximum 90-day e-Visa with single or multiple entries. Read the dates and entry permission on the issued document: the maximum is not a promise of 90 days for every application, nor permission to take employment.
Do Thai citizens need a visa for Vietnam?
Thailand and Vietnam have a mutual visa exemption agreement. Thai ordinary passport holders can enter Vietnam for tourism for up to 30 days per visit without a visa — simply present a passport valid for at least 6 months and a ticket out of Vietnam at immigration.
A longer stay may require an e-Visa. A side trip and re-entry do not by themselves establish that everyone needs a multiple-entry visa; check eligibility for each arrival. Work and study need the appropriate activity-specific permission, not merely a longer e-Visa. The Vietnam e-Visa is issued for up to 90 days, in single-entry or multiple-entry form.
- Tourism up to 30 days: visa-exempt, nothing to file in advance
- Beyond exemption: check an e-Visa; assess each re-entry separately
- e-Visa valid up to 90 days, single or multiple entry
- Passport must be valid at least 6 months from arrival
How to apply for the Vietnam e-Visa and what to prepare
Apply only through the official Vietnam Immigration Department portal (evisa.gov.vn). Fill in personal details exactly as in the passport, upload a front-facing photo and the passport bio page, choose entry and exit checkpoints that match your real itinerary, then pay the fee online as shown by the system on the day you apply.
Once approved, download the e-Visa as a PDF using your application code and print it to show with your passport at check-in and immigration. The details on the e-Visa must match your passport and the checkpoints you actually use.
- Apply only via evisa.gov.vn, the official domain
- Front-facing photo on a plain background + passport bio page scan
- Entry/exit checkpoints must match your actual tickets
- Print the e-Visa PDF and carry it with your passport
Common mistakes and how to avoid them
Frequent problems are choosing an entry checkpoint that does not match the real ticket, mistyping names or passport numbers, uploading photos that fail the size rules, and treating repeated travel as proof that an e-Visa is compulsory. Many lookalike agent sites mimic the official portal — check the domain carefully before paying.
If your plans change after the e-Visa is issued, such as a different entry point, you may need a new application. Apply once your itinerary is fixed and allow processing time before departure. If you are unsure whether your case is exempt or needs an e-Visa, our team can check for you first.
How we work, step by step
- Check if the 30-day exemption covers you. Tourism up to 30 days, check the passport, intended activity and each arrival against current exemption rules.
- Fix your itinerary and checkpoints. If you need an e-Visa, settle the plan first — the form requires entry and exit checkpoints.
- Prepare the photo and passport scan. A plain-background front photo and a legible scan of the passport bio page.
- Complete the form at evisa.gov.vn. Match the passport exactly; keep the application code to track status.
- Pay the fee online. Pay the amount shown on the day you apply and keep the receipt.
- Download and print the e-Visa. Check the result with your application code; print the PDF to show with your passport.
Questions we are asked most
Do Thai citizens need a visa for Vietnam?
Not for tourism up to 30 days — Vietnam exempts Thai passports. You only need a passport valid for 6 months and an onward ticket. Check an e-Visa for a longer stay; repeated travel alone does not establish a visa requirement.
How long does the Vietnam e-Visa take?
Processing times vary. Apply several days before travel and track the status with your application code on the Immigration Department system.
Which website is the official e-Visa portal?
The Immigration Department announced evisa.gov.vn and thithucdientu.gov.vn as its official portals. Beware of lookalike agent sites that add service fees.
What if I chose the wrong entry checkpoint?
The checkpoints on your e-Visa should match your actual travel. If plans change after approval, you may need to apply again — so apply once the itinerary is fixed.
Can I visit Cambodia and re-enter Vietnam on the exemption?
Assess eligibility for the new arrival separately with Vietnamese authorities. If you use an e-Visa, obey its actual single/multiple-entry permission; do not assume every return trip requires a multiple-entry e-Visa.
How long can I stay on an e-Visa?
The Vietnam e-Visa is issued for up to 90 days, single or multiple entry — choose the option that matches your itinerary when filling the form.
