The Thailand Non-Immigrant B (Non-B) visa is the mandatory entry permit for any foreigner who intends to work, take employment, or conduct business activities inside Thailand. Without it, a work permit cannot legally be issued, meaning no employer can onboard a foreign national for paid work. In 2026, the process involves an online e-Visa application portal, updated document requirements, and embassy-specific rules that catch many applicants off guard. This guide breaks down exactly who qualifies, what documents are needed, what it costs, and what to watch out for before you apply.

TL;DR
  • The Non-Immigrant B visa is a prerequisite for any foreign worker seeking employment in Thailand - a work permit cannot be obtained without it.
  • Applicants must secure a job offer and obtain documentation from their Thai employer before applying.
  • Non-immigrant B visa requirements include a valid passport, employer-backed documents, educational certificates, and a completed visa application form.
  • The standard Thailand work visa fees are approximately 2,000 THB for a single-entry and 5,000 THB for a multiple-entry visa, though these may vary by embassy.
  • After entry, a separate work permit application must be submitted to the Department of Employment.

What Exactly Is the Non-Immigrant B Visa and Who Needs It?

The Non-Immigrant B visa is a category of Thai visa specifically designed for foreigners entering Thailand for business, employment, or work-related purposes. According to the Thai Ministry of Foreign Affairs, this visa category covers two distinct scenarios: those who already have a confirmed job offer with a Thai employer, and those attending business meetings or conducting short-term business activities without performing local employment.

If you are being hired by a Thai company, a BOI-promoted firm, or even a foreign-owned business legally registered in Thailand, you need this visa. Attempting to work on a tourist visa or visa exemption is illegal under Thai labour law and can result in fines, detention, or a ban from re-entry.

  • Employment: Foreign nationals hired by companies registered in Thailand.
  • Business activities: Attending meetings, negotiating contracts, or conducting business without receiving Thai-sourced income.
  • BOI/IB track: The Non-Immigrant IB Visa is a related sub-category for foreign professionals and technical experts employed by BOI-promoted companies, offering a streamlined pathway.

What Are the Non-Immigrant B Visa Requirements in 2026?

Meeting the non-immigrant B visa requirements means satisfying two sets of criteria: your personal eligibility documents, and the supporting documentation from your Thai employer. Missing either side is the most common reason applications are delayed or refused.

Applicant Documents

  • Passport or travel document with at least 6 months validity remaining, as confirmed by the Thai MFA.
  • Completed Non-Immigrant Visa application form (submitted via the e-Visa portal or in person).
  • Recent passport-sized photographs meeting Thai embassy specifications.
  • Educational certificates, professional qualifications, and, where required, apostilled copies.
  • Evidence of sufficient funds (bank statements are commonly requested).

Employer-Provided Documents

  • Employment contract or offer letter signed by an authorized company representative.
  • Company affidavit (DBD-certified) and business registration certificate.
  • Company list of shareholders and the latest financial statements or VAT returns.
  • A letter confirming the position, salary, and need for a foreign specialist.

Applicants should also anticipate embassy-specific unlisted requirements - additional documents that are not published on official portals but are routinely requested at certain consulates. This is one of the least-discussed but most impactful variables in the application process.

How Much Does the Thailand Work Visa Cost in 2026?

Understanding work visa Thailand cost and thailand work visa fees upfront prevents budget surprises. Costs vary slightly depending on the issuing embassy or consulate, but the standard fee structure is consistent across most Thai missions abroad.

Visa Type Validity Permitted Stays Approximate Fee
Non-B Single-Entry 3 months 1 entry, up to 90 days per stay ~2,000 THB / ~USD 60
Non-B Multiple-Entry 1 year Multiple entries, up to 90 days each ~5,000 THB / ~USD 150

As noted by the Royal Thai Consulate-General in Ho Chi Minh City, holders of this visa are entitled to stay in Thailand for a maximum of 90 days per entry. Extension of stay must be applied for at a Thai Immigration office inside the country. Beyond the visa fee, budget for the separate work permit fee (typically 750 to 3,000 THB depending on permit duration), translation costs for foreign-language documents, and potential apostille fees.

What Is the Step-by-Step Process to Obtain a Thailand Work Permit Visa?

The thailand work permit visa process is a two-stage procedure. The visa gets you into the country legally; the work permit authorizes you to perform work once inside.

  1. Secure a job offer from a legally registered Thai company willing to sponsor your application.
  2. Collect employer documents (see the list above) - the employer must initiate much of this paperwork.
  3. Submit your Non-B visa application at the nearest Royal Thai Embassy or via the e-Visa portal, where available.
  4. Enter Thailand on your Non-B visa within the validity window.
  5. Apply for a work permit at the Department of Employment upon entry. This requires a valid Non-Immigrant B visa, three passport-sized photographs, and your educational certificates.
  6. Receive your work permit and begin employment legally.

One underappreciated step: the employer's documentation must be entirely consistent with their registered business scope. A discrepancy between a company's registered activities and the role being offered is a frequent grounds-for-refusal issue that rarely gets flagged until it is too late.

What Are the Most Common Eligibility Mistakes That Lead to Rejection?

  • Applying from within Thailand on a tourist visa: Most embassies require the Non-B application to be made from outside Thailand or from your country of residence.
  • Employer documents that don't meet capital requirements: Thai companies sponsoring foreign workers must typically demonstrate sufficient registered capital (often 2 million THB per foreign worker).
  • Missing apostille on educational certificates: This is particularly common for teachers and professionals whose qualifications were issued in non-Hague Convention countries.
  • Applying for the wrong sub-category: The standard Non-B and the BOI Non-IB track have different document sets and processing timelines.
  • Overlooking embassy-specific rules: Individual Thai embassies may have localized requirements beyond the official MFA checklist.

Frequently Asked Questions

Can I convert a tourist visa to a Non-Immigrant B visa inside Thailand?
Generally, no. Most Thai embassies require the Non-B application to be submitted from outside Thailand. Attempting to change status from within Thailand is rarely approved and is not a recommended strategy.
How long does it take to process a Non-Immigrant B visa?
Processing typically takes 3 to 7 business days at most Thai embassies, though timelines vary by location. Some consulates in high-demand cities may take longer during peak periods.
Does my employer need to be a BOI-promoted company?
No. Any legally registered Thai company can sponsor a Non-B visa. BOI-promoted companies use the Non-IB track, which offers faster processing and a longer initial stay for qualified experts.
What are the financial evidence requirements for a Non-B visa application?
The Thai MFA requires evidence of adequate finance of 20,000 THB per person or 40,000 THB per family. Work permit eligibility is also subject to employer-side requirements such as minimum registered company capital, typically 2 million THB per foreign worker.
Can my family join me on a Non-Immigrant B visa?
Dependants (spouse and children) can apply for a Non-Immigrant O (Other) visa to join a Non-B holder. They cannot work on this dependent visa without obtaining their own Non-B and work permit.
How many foreign employees can a Thai company hire?
The standard ratio is four Thai employees for every one foreign worker, though BOI-promoted companies and those in specific sectors may be exempt from this ratio requirement.
Do I need a work permit for every type of work activity in Thailand?
If you are attending meetings, conferences, or short-term business discussions without receiving Thai-sourced income, a Non-B visa for business purposes may be sufficient without a work permit. Performing any form of employment or paid work requires both the visa and the permit.
