What the Thailand business and investor eVisa covers
Thailand publishes no single universal business investor visa, and the online eVisa system lists the business and investor category, written as non-immigrant B/IB, among its nine types. A Thailand business visa case normally rests on business activities such as meetings and conferences or employment-related travel organised by a Thai organisation, while the investor side covers investment activity where company, promotion, property or programme rules can apply. Because validity, number of entries and required documents differ between the eVisa categories, treat every figure here as a published reference point and confirm the current position with your responsible mission.
Work permission is a separate step. A Non-Immigrant B visa is not, by itself, a work permit, and a business visit never substitutes for Thai employment approval. Anyone who will carry out work in Thailand must follow the applicable work-permission process first, and our Thailand work visa and work permit page explains that route.
A Non-Immigrant B file usually shows a genuine business or employment purpose connected to Thailand, supported by documents from the Thai company, employer or business counterpart. Business registration, licence, shareholder or company information is requested where relevant, employment evidence such as position, qualifications and work details is central to employment-related cases, and investment records matter when the activity itself is investment rather than a meeting.
Who the business and investor route suits
Start from the activity rather than the label. Short business visits, employment in Thailand and investment cases are different scenarios, and each one points to a different set of documents, so describe what you will really do before you pick a category. The list below shows the purposes commonly connected to this route, including one important overlap with the tourist category.
- Business meetings, negotiations and counterparty discussions with a Thai company.
- Conferences, conventions and exhibitions that are part of a business trip.
- MICE participation, meaning meetings, incentives, conventions and exhibitions supported by the Thailand Convention and Exhibition Bureau, which published guidance lists among tourist eVisa purposes, so check which category fits before you apply. Our Thailand visa types page compares the categories side by side.
- Investment activity, where company, promotion, property or programme-specific rules decide the correct route.
- Employment-related travel where a Thai employer or organisation sponsors the case and handles its own paperwork.
If your trip is only a short visit to a conference or a series of meetings, compare it against the tourist purposes first, because published guidance places MICE participation inside the tourist category. Naming the real activity early keeps the application, the invitation and the documents telling the same story.
Documents and evidence that may be requested
The responsible Thai embassy or consulate may request documents beyond any general checklist, so prepare evidence that explains the activity, your role and the Thai organisation involved. Nothing below is a promise of approval or a fixed list; it is a starting set of evidence that missions commonly ask for in business and investor cases.
| Evidence area | What it shows | What may be included |
|---|---|---|
| Applicant identity | Who is applying, and where they are legally resident | Passport biodata page, recent face photograph, current-location evidence and residence documents requested by the mission |
| Thai organisation | Who invites or employs you, and on what basis | Invitation or employment letter, business registration, licence, shareholder or company information, BOI or programme documents where relevant |
| Purpose and qualifications | Why you are travelling, and what your role is | Business itinerary, role description, qualifications, financial evidence, investment records or endorsement documents where relevant |
Coordinate anything sensitive with the Thai company or programme contact first, keep your file consistent with the Thailand documents checklist, and review the passport and arrival conditions on our Thailand entry requirements page before you upload anything.
Process and timing for the business eVisa
The online process asks you to choose the specific eVisa type that matches your purpose, complete the application form, cover any service fee and wait for the confirmation email. Published service guidance for the online system says to submit at least 15 business days before your planned departure, with standard processing of about 15 business days from submission. Treat both as published reference figures from the application service linked from this site rather than a date promised by any Thai authority, and build in more room if your trip date is fixed.
Define the activity
Business meeting, employment, promotion project, startup, investment or long-term residence.
Identify the route
Compare non-immigrant B, the investor category, BOI-related options or another category that matches the activity.
Collect the evidence
Coordinate with the Thai employer, company, programme or investment authority where needed.
Check the mission rules
Submit through the official process and follow the embassy or consulate's current instructions.
If you have not submitted online before, our how to apply for the Thailand tourist eVisa walkthrough shows the structure of the same online form step by step, and the Thailand eVisa status check page covers how to follow a decision once your file is submitted.
Business, work and tourist routes compared
These categories are related but not interchangeable. A visa is permission to seek entry for a stated purpose; it does not automatically grant a work permit or guarantee approval for a particular role, so match the route to the activity before you pay anything.
| Route | Typical fit | Keep in mind |
|---|---|---|
| Business and investor (non-immigrant B/IB) | Meetings, conferences and employment-related business travel | Documents follow the activity, and the visa alone is never a work permit |
| BOI-promoted employment and investment | Working with a qualifying Board of Investment-promoted company, or investing through that channel | Employer and project documentation are central; see the Thailand investment and BOI visa page |
| SMART Visa | Talent, investors, executives, startup entrepreneurs and dependents in targeted industries | A separate programme administered through the Board of Investment, with category-specific criteria |
| Long-Term Resident (LTR) | Qualifying wealthy individuals, pensioners, work-from-Thailand professionals, highly skilled professionals and eligible dependents | Its own qualification groups and continuing conditions, assessed through the BOI process |
| Tourist eVisa | Leisure, family visits, medical treatment, training and MICE participation | Published tourist purposes, not a substitute for an employment or investment case |
| Work visa and work permit | Taking up work for a Thai employer | A separate permission from the visa, handled under the applicable Thai employment process |
Investment alone does not identify the correct visa without reviewing the activity and the qualification rules, so do not treat every investor or remote-work case as a standard business visa. VistoRoute can help organise the information you submit and highlight the documents that need attention, while the final visa category, endorsement, work permission and admission decision belong to the relevant Thai authorities.
Thailand business eVisa FAQs
What does the Thailand business and investor eVisa cover?
It is the online business and investor category listed under Thailand's eVisa system, written as non-immigrant B/IB. Published guidance associates it with business activities such as meetings and conferences and with investment-related travel, and your responsible mission sets the conditions for approval.
Does a Thailand business visa allow me to work in Thailand?
No. A visa is permission to seek entry for a stated purpose, and a Non-Immigrant B visa is not by itself a work permit. Anyone who will carry out work must follow the applicable Thai employment and work-permission process first.
Can I attend MICE events on a tourist eVisa?
Published lists of tourist eVisa purposes include participation in meetings, conventions, exhibitions and incentives supported by the Thailand Convention and Exhibition Bureau. If your real purpose is business negotiation or employment, review the business and investor category instead and confirm the fit with your responsible mission.
Which documents may be requested for a business eVisa?
A mission may ask for an invitation from the Thai company, business registration or company information such as licences and shareholder details, employment evidence, a business itinerary, qualifications, financial evidence and investment records. The responsible embassy or consulate can request documents beyond any general checklist.
How far ahead should I apply for a Thailand business eVisa?
Published service guidance for the online process suggests submitting at least 15 business days before your planned departure, with standard processing of about 15 business days from submission. Treat both figures as published reference guidance from the application service linked from this site rather than a date promised by any Thai authority.
How long can I stay on a Thailand business or investor visa?
Validity period, number of entries and maximum stay differ between eVisa categories, so this page states no fixed figure for the business and investor route. Confirm the current position for your category with your responsible Thai mission before you travel.
