A foreign professional who intends to work in Thailand will generally need the correct permission to work, supported by an appropriate employer and immigration status. A business visa and a work permit serve different purposes. Holding a Non-Immigrant B Visa does not, by itself, give a person general permission to begin working.

The practical starting point is to review the proposed work, the applicant and the employer together. The job must be open to foreign nationals, the applicant should be suitable for the position, and the employer must be able to support the relevant application route. Where a company is still being established, these matters should be considered before its capital, office and staffing arrangements are finalised.

Thailand’s e-WorkPermit System

The Department of Employment launched the nationwide e-WorkPermit service on 13 October 2025. The system is used for work permit applications and a range of related notifications and changes.

The move online changes the filing method, but not the need to prepare a coherent application. Employer information, the proposed position, immigration status and supporting records must still be reviewed. The system may also require electronic account setup, data entry, uploaded documents, fee payment and subsequent steps directed by the Department of Employment.

Online filing should therefore not be confused with automatic approval. An application may be returned for clarification or further evidence, and processing time will depend on the route, the completeness of the submission and officer review.

A Business Visa and a Work Permit Are Different

This distinction explains why the same company and employee may need to coordinate more than one application. The Department of Employment considers work authorisation, while immigration matters remain subject to the Immigration Bureau and, for visas issued overseas, the relevant Royal Thai Embassy or Consulate.

Who Generally Needs Permission to Work in Thailand?

Foreign nationals who perform work in Thailand generally require permission unless a specific exemption or alternative legal route applies. The legal concept of work should not be limited to receiving a Thai salary. Directing operations, providing services, meeting clients in a working capacity or performing duties for a business may still require review.

A person should not assume that permission is unnecessary merely because:

• the employer or client is located outside Thailand;
• payment is made into a foreign bank account;
• the work will be unpaid;
• the person is a shareholder or director;
• the activity will last only a short time; or
• the person already holds a Non-Immigrant B Visa.

The facts should be checked before the activity begins. Certain visa categories, promoted projects and statutory exemptions can produce a different result, but they should be confirmed rather than assumed.

Urgent or Necessary Work Is a Separate Route

Thai law provides a notification route for qualifying urgent, necessary or ad hoc work that can be completed within 15 days. This is a narrow procedure under Section 61 of the Emergency Decree on Managing the Work of Aliens, not a general 15-day permission attached to a business visa.

The nature of the work, the timeframe and the notification requirements must fit the route. A foreign visitor should not begin ordinary employment and later describe it as urgent work simply because the visit is short. Where the work will continue, recur or form part of an ongoing position, the appropriate standard or special work-authorisation route should be considered.

Main Work Authorisation Routes

Not every route is available to every applicant. BOI promotion, Smart Visa status and other special frameworks have their own eligibility requirements. A company should first identify the route it actually qualifies to use, rather than choosing the route that appears to have the shortest document list.

What Does a Standard Employer Need to Show?

A standard work permit application is supported by both the foreign applicant and the employer. The Department of Employment may consider whether the employer is an operating business and whether the proposed foreign position is credible and appropriate.

Depending on the application, relevant employer matters may include:

• corporate registration and current company particulars;
• the company’s registered and paid-up capital;
• the actual business activity and business licences, where required;
• the workplace and evidence that the company operates there;
• VAT, tax and accounting records appropriate to the company’s stage of operation;
• Thai employees and Social Security records;
• the employment position, duties, salary and need for the foreign employee; and
• existing foreign employees and the route used for each application.

A newly incorporated company will not have the same operating history as an established business. That does not necessarily prevent an application, but the available documents and the company’s readiness should be reviewed before a start date is promised to the employee.

Registered Capital and Thai Employee Benchmarks

For a standard non-BOI company, THB 2 million of registered capital for each foreign employee is commonly used as a planning benchmark. Four Thai employees for each foreign employee is another figure frequently encountered, particularly where the work permit is intended to support a one-year extension of stay.

These figures should not be presented as universal rules that decide every application. The relevant requirements can differ according to the employer, the applicant, the immigration objective and any special status or concession. For example, BOI-promoted companies and certain applicants with Thai family relationships may be considered under different criteria.

Capital alone does not create an entitlement to a work permit. The company’s paid-up position, staffing, Social Security, tax compliance, office and actual operations may also be relevant. Equally, a work permit decision and an immigration extension decision are separate. A company should plan for the outcome it needs, rather than checking only one figure.

If You Do Not Yet Have a Thai Employer or Company

An individual cannot create a standard employer-sponsored work permit merely by applying in a personal capacity. There must be an employer or another qualifying legal basis for the proposed work.

If the applicant intends to operate a new business, it may be necessary to establish and prepare a Thai company before the work permit application can proceed. The company should be designed around the intended business activity, ownership, funding, office, licensing and future employment plans, not formed solely around a work permit number.

Our page on company registration in Thailand explains how those structural and operational matters are reviewed before incorporation.

What Information Is Usually Required?

The exact document list depends on the application route and the facts. A reliable review therefore begins with categories of information rather than an old generic checklist.

Information about the foreign applicant

• passport and current immigration status;
• nationality and current location;
• education, professional qualifications and relevant experience;
• proposed position, duties and salary;
• employment history or existing Thai work authorisation, where relevant;
• medical or other supporting evidence required for the route; and
• family relationship documents if a specific concession is relied upon.

Information about the employer

• current corporate documents and shareholder information;
• capital and share-payment records;
• tax, VAT and Social Security records appropriate to the application;
• employee information;
• office and workplace evidence;
• employment documents and an explanation of the proposed role; and
• business licences or regulatory approvals where applicable.

Documents may need to be current, signed, certified, translated or supplemented following officer review. The e-WorkPermit system may also prescribe particular formats and data fields. The application list should therefore be confirmed for the relevant route at the time of filing.

A Practical Work Permit Application Sequence

1. Define the work. Confirm the actual position, duties, workplace and intended start date.
2. Identify the correct route. Determine whether the application is standard, BOI-supported, exempt or genuinely urgent and short-term.
3. Review employer readiness. Check the company’s capital, staffing, Social Security, tax position, office and licences.
4. Coordinate immigration status. Confirm the visa or permission to stay required for the selected route and future extension plans.
5. Prepare consistent evidence. Align the job description, employment documents, qualifications and company records.
6. File through the applicable system. Complete the e-WorkPermit or special-route process and respond to requests for further evidence.
7. Confirm approval before work begins. Do not treat submission of an application as permission to work.
8. Manage later changes. Review renewals and changes to the employer, position, duties or status before they take effect.

This order avoids a common problem: beginning with a document list and discovering later that the employer, role or immigration plan does not support the intended outcome.

Work That Is Restricted to Thai Nationals

Permission to work cannot ordinarily be obtained for an occupation reserved for Thai nationals. The restricted occupations include work prohibited outright and work permitted only under specified conditions.

The job title is not the only consideration. The authorities may examine what the foreign applicant will actually do. A management or specialist title should therefore be supported by duties that are consistent with the position, the applicant’s background and the employer’s business.

If a role combines permitted professional duties with activities that may be restricted, the duties should be reviewed before the employment documents and application are prepared.

After Permission to Work Is Granted

Approval is tied to the applicable legal route and the information recorded for the employment. The foreign employee and employer should keep the authorisation accessible and ensure that the actual work remains consistent with the approved position and conditions.

Later events may require action through e-WorkPermit or the relevant authority, including:

• renewal before the permission expires;
• a change of employer;
• a material change in position or duties;
• termination of employment;
• changes to personal or company information; or
• coordination with an extension or change of immigration status.

The timing and form of the required step depend on the event and the route. It is generally safer to review a proposed change before it occurs rather than assume the existing permission will continue unchanged.

Common Work Permit Misunderstandings

“I can work as soon as my Non-B Visa is issued.”

No. The visa and permission to work are separate. The applicant should confirm that the relevant work authorisation has been granted or that a specific exemption or notification route applies before beginning work.

“Submitting the work permit application lets me start working.”

Submission is not approval. Work should begin only when the required permission or legally effective notification is in place.

“Every company only needs THB 2 million and four Thai employees.”

Those are useful planning benchmarks for many standard cases, but they do not decide every work permit or immigration application. The complete employer, applicant and route must be reviewed.

“A company director does not need a work permit.”

Being named as a director does not automatically exempt a foreign person from work-authorisation requirements. The person’s actual activities in Thailand and any applicable legal route should be considered.

“Remote work for an overseas company is automatically outside Thai work permit law.”

The location of the employer or bank account does not by itself settle the position. The activity performed in Thailand, the person’s status and any applicable exemption should be reviewed.

Frequently Asked Questions

Can I obtain a Thailand work permit without a Thai company?

A standard employment application generally requires a qualifying employer or legal entity in Thailand. Other routes may apply to BOI-promoted employment, Smart Visa holders or persons covered by a specific statutory framework. An individual cannot obtain an ordinary work permit without an employment or other qualifying basis.

Do I need a Non-Immigrant B Visa before applying?

A suitable non-immigrant status is commonly required for standard employment, usually in the Non-Immigrant B category. The timing and sequence can differ where the employer applies while the person is outside Thailand or where a special route applies. The visa plan should be coordinated with the work permit application.

How long does a Thailand work permit application take?

There is no single reliable timeframe for every application. Timing depends on the route, account and document readiness, fee payment, requests for additional evidence and Department of Employment review. Immigration or overseas visa steps may add separate time.

How much registered capital is required?

THB 2 million per foreign employee is a commonly applied planning benchmark for a standard non-BOI company. It is not a universal rule or guarantee. The employer’s paid-up capital, operations, staffing and other circumstances may also be relevant, and special routes may use different criteria.

How many Thai employees are required?

Four Thai employees per foreign employee is commonly used when planning a standard work permit together with a one-year extension of stay. The applicable position can differ by route and circumstances. Work permit and immigration requirements should be checked separately.

Can I work while the application is pending?

Generally, the fact that an application has been submitted does not itself authorise work. The person should wait until the applicable permission has been granted unless a legally effective exemption or notification route applies.

Can a work permit be transferred to a new employer?

A change of employer normally requires specific action and cannot be treated as an automatic transfer of the existing permission. The termination, new application and immigration consequences should be coordinated before the change takes effect.

Does a work permit automatically give me a one-year stay?

No. Permission to work and permission to stay are separate. A one-year extension remains subject to Immigration Bureau requirements and supporting documents.

Preparing for a Work Permit Review

The most useful initial information is usually:

• your nationality and current location;
• your present visa or immigration status;
• the proposed Thai employer and whether it is already operating;
• the proposed position and principal duties;
• your qualifications or relevant professional experience;
• the employer’s approximate capital and Thai staffing position; and
• the intended employment start date.

A brief outline is sufficient for an initial enquiry. Further documents can be identified after the relevant route and principal issues have been reviewed.

Initial enquiries are handled by email so that our legal team can review the relevant information before recommending the appropriate course of action. You may provide a brief outline at the first stage and add further information where required.
