Complete Guide: Non-Immigrant B (Business) for Vietnam Citizens (2026)
As one of the most-requested Thailand visa pathways for Vietnam nationals, the Non-Immigrant B (Business) requires careful navigation of both Vietnam and Thai bureaucracy. Our team has handled 123+ cases specifically for 🇻🇳 Vietnam passport holders in the past 12 months, with a 92% first-time approval rate that significantly exceeds the industry average of 78%.
Why Vietnam Citizens Choose the Non-B Pathway
The Non-B visa is particularly well-suited for Vietnam nationals because of Thailand's growing economy, BOI investment incentives, and the strong Vietnam business community already established here. With a duration of 1 year(s), this visa provides stability for medium-to-long term stays.
Vietnam-Specific Application Process
The Royal Thai Embassy in Vietnam processes visa applications according to specific local procedures that differ from other jurisdictions. Key differences for Vietnam applicants include:
- Document language: All Vietnam-issued documents must be apostilled (Hague Convention) or legalized through the Vietnam Ministry of Foreign Affairs before submission.
- Translation requirements: Thai translation must be performed by an MFA-recognized translator — we handle this in-house with certified linguists familiar with Vietnam legal terminology.
- Banking proof: Vietnam bank statements are accepted but require additional notarization and translation. Major Vietnam banks have established protocols with the Thai embassy.
- Police clearance: Must be issued by Vietnam federal/national authorities, not local police. Validity is 90 days from issuance.
- Medical certificate: Can be issued by Thai or Vietnam hospitals; we recommend Thai hospitals for cost and turnaround speed.

Common Pitfalls Specific to Vietnam Applications
Beyond the universal rejection reasons listed above, Vietnam applicants face specific challenges that our team screens against:
- Apostille vs. Legalization confusion: Vietnam is not a Hague Convention member, so documents need full embassy legalization rather than apostille.
- Name transliteration: Vietnam names often get romanized inconsistently across documents. We standardize to passport spelling to avoid Immigration confusion.
- Address format: Thai immigration prefers full Thai-style addresses. We translate Vietnam addresses to Thai conventions.
- Date format: Most date formats are compatible, but Buddhist Era (BE) conversion is required.

We serve Vietnam clients across all 77 provinces of Thailand. Most Vietnam expatriates concentrate in Bangkok (Sukhumvit, Sathorn, Silom), Chiang Mai (Nimmanhaemin), Pattaya (Jomtien, Pratumnak), Phuket (Patong, Kata, Rawai), and Hua Hin.
