Thailand Business Visa
Foreign nationals who need to conduct business in Thailand - meetings, site visits, contract negotiations, or setting up a company - usually require a Non-Immigrant Category B visa before arrival. This is commonly called the Thailand business visa.
Thai Visa Centre in Bangkok helps employers, entrepreneurs, and corporate travellers navigate the difference between a business visa, a work permit, and a tourist stamp. This guide focuses on the entry visa stage - what you apply for at a Thai embassy or through the e-Visa portal.
Meetings, business setup, pre-work permit
Limited business activity; employment needs work permit
90 days per entry
Company invitation, business profile, sometimes MOU

What is a Thailand business visa?
The business visa is a Non-Immigrant B (NI-B) visa issued by a Royal Thai Embassy or Consulate abroad. It authorises entry for business-related activities, not tourism.
A standard single-entry NI-B usually grants an initial stay of 90 days. Multiple-entry versions exist for frequent travellers. Exact validity is printed on your visa sticker or e-Visa approval.
- Attending board meetings or negotiations
- Exploring investment or partnership opportunities
- Setting up a Thai company (often alongside BOI promotion)
- Entering Thailand to apply for a work permit after a job offer
Who needs a business visa?
You generally need NI-B if:
Some exempt nationalities may enter for very short business trips under exemption rules, but repeated or long business stays usually require NI-B.
- Your nationality is not visa-exempt for business purposes
- You will stay beyond exemption limits or need multiple entries for business
- An employer or Thai company is sponsoring your visit
- You plan to convert to a long-term work visa inside Thailand
How to apply
Applications are submitted through the Thailand E-Visa portal or at your local Thai embassy.

Once in Thailand on NI-B:
Long-term business residents often progress: NI-B → work permit → annual extension, or BOI-promoted company routes with extended privileges.

| Milestone | Action |
|---|---|
| Two weeks before travel | Download the live checklist from thaievisa.go.th and confirm embassy jurisdiction for your passport. |

Document checklist
Embassy-grade document quality prevents most avoidable rejections. Keep originals and colour scans organised before submission.
| Document | Detail |

How this topic fits other visa pathways
Many immigration problems start with choosing the wrong entry category. Use this comparison to sanity-check whether your current plan matches your real activity in Thailand.
| Route | Best fit | Limit |
|---|---|---|
| Visa exemption / tourist | Short holidays and first visits under current nationality rules. | Not for employment, long-stay settlement, or repeated border-run strategies. |
| Non-Immigrant long-stay | Retirement, marriage, business, education, and other category-specific routes. | Financial proof, reporting, and extension rules vary by sub-category. |
| DTV / LTR / Privilege | Remote workers, professionals, investors, and premium long-stay profiles. | Higher documentation bar; activity must match visa category. |
| Visa on Arrival | Eligible nationalities on very short tourism trips at approved checkpoints. | Fixed short stay; not for work, study, or long-term residence. |
See our Thailand lifestyle guide and visa FAQ hub for broader long-stay planning.
Compliance reminders
Long-stay holders in Thailand must keep address registration, reporting, and visa activity aligned. These habits reduce extension friction and overstay risk.
- Complete TDAC before every entry: long-stay visa holders included.
- Confirm TM30 is filed when you change address or check into long-stay accommodation.
- Track 90-day reporting or annual reporting dates for your visa tier.
- Obtain re-entry permits before leaving on single-entry extensions.
- Match daily activity to visa category, tourism stamps do not authorise employment.
When to ask TVC
Speak with us before you overstay, change visa category, or submit a complex embassy pack. Early review is cheaper than emergency correction at the airport or immigration detention.

- Single-entry visa holders travelling regionally without a re-entry permit

Frequently asked questions
These answers provide orientation only and do not replace case-specific legal advice.
Q:Can I convert a tourist visa to a business visa in Thailand?
A:Sometimes, at immigration discretion, but it is not guaranteed. Applying for the correct visa before travel is safer.
Q:How long does business visa processing take?
A:Plan one to three weeks via e-Visa; complex cases longer. Employer-sponsored work visas may need additional Ministry of Labour coordination.
Q:Do I need BOI approval for a business visa?
A:Not for every short business visit. Board of Investment promotion applies to qualifying investment projects - see BOI for LTR and investment visas separately.
Q:Is NI-B the same as SMART visa?

A:Dependents typically apply for Non-Immigrant O tied to your status, with separate documentation.
