B
Non-Immigrant B
Commonly used for business activities and employment-related travel. The documents depend on whether you are visiting for business or taking a job with a Thai organization.
Business & investment
Thailand Business & Investor Visa
Thailand does not use one universal “business investor visa.” The appropriate route depends on whether you are attending meetings, taking employment, working with a BOI-promoted company, building a qualifying startup, investing, or seeking a long-term residence programme.
Choose the activity first. The visa category follows the activity.
Which Thailand business route fits your activity?
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.
BOI
BOI-supported employment
Employees of qualifying Thailand Board of Investment-promoted companies follow a BOI-related process. The employer and project documentation are central to the case.
S
SMART Visa
A BOI-administered programme for qualifying talent, investors, executives, startup entrepreneurs, and dependents in targeted industries. Its criteria are category-specific.
LTR
Long-Term Resident
The LTR programme is designed for qualifying wealthy individuals, pensioners, work-from-Thailand professionals, highly skilled professionals, and eligible dependents.
IV
Investment activity
Investing in Thailand can involve company, BOI, property, or programme-specific rules. Investment alone does not identify the correct visa without reviewing the activity and qualification.
ME
Business meetings
Short business visits and employment in Thailand are different scenarios. Describe the real activity and confirm the mission’s required documents before applying.
Non-Immigrant B: what the case usually needs to show
- A genuine business or employment purpose connected to Thailand.
- Supporting documents from the Thai company, employer, or business counterpart.
- Business registration, licence, shareholder, or company information where requested.
- Employment evidence, position, qualifications, and work details where the application is employment-related.
- A clear distinction between the visa application and any separate work-permit or labour approval process.
Important work-permission distinction
A Non-Immigrant B visa is not, by itself, a work permit. A foreign national must follow the applicable Thai employment and work-permission process before carrying out work in Thailand.
SMART Visa and LTR are separate programmes
Use the official programme criteria rather than treating every investor or remote-work case as a standard business visa.
SMART
Targeted-industry talent and startups
SMART Visa categories are administered through Thailand’s Board of Investment and are designed for qualifying professionals, executives, investors, startup entrepreneurs, and dependents. Criteria, endorsements, and privileges vary by category.
LTR
Long-term residence programme
LTR has its own qualification groups and continuing conditions. It is not simply a longer version of a tourist or ordinary business visa, and applications are assessed through the BOI process.
Prepare the right evidence
The responsible Thai embassy or consulate may request documents beyond a general checklist. Prepare evidence that explains the activity, the applicant’s role, and the Thai organization or programme involved.
01
Applicant identity
Passport biodata page, photograph, current-location evidence, and any residence documents requested by the mission.
02
Thai organization
Invitation, employment, company, BOI, or programme documents appropriate to the activity and visa category.
03
Purpose and qualifications
Business itinerary, role description, qualifications, financial evidence, investment records, or endorsement documents where relevant.
A clearer application sequence
Do not begin with a generic “investor visa” label. Start with the actual activity and confirm the competent authority.
Define the activity
Business meeting, employment, BOI project, startup, investment, specialist role, or long-term residence.
Identify the route
Compare Non-B, BOI, SMART, LTR, or another category that matches the activity.
Collect evidence
Coordinate with the Thai employer, company, programme, or investment authority where needed.
Check mission rules
Submit through the official process and follow the embassy or consulate’s current instructions.
