Work Permit in Thailand: documents and work permit

A Work Permit in Thailand is obtained separately from the visa. For regular employment on a Non-B work visa, it must be obtained before work begins: a visa alone is not enough. Special routes have their own conditions, including the possibility of temporary work for a holder of long-term resident (LTR) status while the permit application is under review.

Below we explain how to divide preparation between you and the company, choose the procedure, understand the fees, and handle changes after dismissal or moving to another employer. The entry stage is explained separately in application for a Non-B work visa. The main practical question is which confirmation allows you to start your actual duties, not just to submit documents.

Current as of publication. Conditions may change; before applying, check the official requirements of the chosen procedure. Before agreeing on the first working day, determine who is responsible for the documents, expenses, and verification of employment and immigration status.

How a work permit differs from a visa and permitted stay

A visa, the right to work, and permitted stay serve different purposes. Obtaining a document under one procedure does not mean the other issues are settled.

The Ministry of Foreign Affairs of Thailand states directly: for regular employment on a Non-B work visa, the permit must be obtained before work begins. Filing an application and preliminary approval do not mean this requirement has been met.

In practice, it is useful to separate the questions: whether you can enter, whether you can remain in the country, and whether you can carry out the agreed work. An answer to one of them does not replace the answers to the others, even if the documents are being prepared with the involvement of one company.

At the same time, the Non-B work visa cannot be presented as the only possible status for every foreign worker. The long-term resident (LTR) program has special provisions, so first the applicable route is determined, and then the conditions for starting the activity.

Requirements for the employer: capital, staff and the chosen procedure

The application depends on both sides. You need information about your position and personal documents, and the company needs an understanding of the applicable procedure and its part of the preparation.

Do not confuse the labor requirements of the Department of Employment (DOE), the conditions for extending stay, and the special regime of the Board of Investment (BOI). The question of capital or staffing only makes sense together with an answer to this: for which procedure and employer category it is checked.

These are questions to agree on, not a mandatory set for all applicants. A universal capital amount or staffing ratio not tied to a procedure cannot be used as a benchmark.

Ask the company to explain which stage each requested confirmation relates to. This makes it easier to tell information for the work permit apart from documents for stay, and not to treat a special condition as a general rule.

If you are considering your own business, the corporate part is explained in company registration in Thailand. The question of your right to personally perform the work still needs to be examined separately.

Worker and company documents: medical certificate and preliminary approval

Documents for the work permit are more convenient to prepare separately from the visa package. Some information may overlap, but the purposes of the applications and approvals differ.

Before collecting papers, ask the company these preparatory questions:

• Which passport details are needed for the chosen route?
• Are photographs required, and what requirements apply to them?
• What confirms education and qualifications for your position?
• What corporate documents does the employer prepare?
• Are medical documents required, and which conditions apply specifically to this procedure?
• Is a preliminary application by the employer provided before your entry?

For an employer to file an application for a foreign specialist who is abroad, the Department of Employment (DOE) portal provides BT.32. This is a specific procedure: it cannot be automatically equated with every preliminary approval under visa instructions.

The same principle applies to the medical certificate. Do not schedule examinations based on someone else’s list, and do not assume that requirements for the original or the document’s validity period are the same for all routes; first determine the list for your procedure.

It is useful to supplement the preparation list with the person responsible for each item: the worker, the company, or both. Separately, note what each document is for — the visa, the work permit, or another stage. This helps you spot gaps before filing without turning someone else’s list into a mandatory one for you.

How to obtain a work permit: sequence of steps

Below is a joint preparation plan, not a set of mandatory stages for any status. If you are already in Thailand or use a special program, the sequence may depend on your route.

1. Agree on the employer and the activity. Record the position and actual tasks, then check whether such work is permissible for a foreigner.
2. Determine the route. Separate the labor procedure, the entry status and the stay conditions.
3. Prepare a list of documents. Divide the personal and corporate parts, and determine whether a preliminary application is needed.
4. Agree on the entry status. Prepare the visa part, if it is required in your situation.
5. Complete the relevant labor procedure. Use the application and procedure provided for your category.
6. Check the basis for starting work. Make sure the application allows you to perform the agreed duties.

Do not rush to set a start date. For the regular route under a Non-B work visa, the end result is the permit obtained, not the company’s promise to finish the process later.

Each preparation stage should have a clear result: agreed duties, the chosen procedure, prepared information, or a received document. This helps you avoid confusing readiness to submit an application with completing the process.

For special categories, the basis may differ. For example, the long-term resident (LTR) program provision on temporary work while an application is under review should be considered separately from regular employment.

Electronic filing and application forms (e-WorkPermit)

The electronic work permit portal contains several procedures. The choice depends on the applicant’s situation and the purpose of the application, not only on how quickly the company wants to start the project.

These procedures are presented on the official portal of the Department of Employment. A short project alone does not give grounds to use BT.34: the nature of the work also matters.

Pay attention to the difference between obtaining a permit, notifying about special work, and processing personnel changes. Having forms on one portal does not make them interchangeable: an application for a specialist abroad serves a different purpose than a notice of dismissal.

The existence of the portal does not prove that the electronic format is mandatory for every category. Nor can one infer from it a general date for ending paper filing or identical technical steps for all applicants.

Cost and processing times: reference fees and limits

The cost of a work permit in Thailand should be kept separate from visa payments and the full preparation budget. The table lists different fees, indicating the scope of each.

The fees listed in the Thailand government reference (Thailand.go.th) relate to the described mutual recognition of qualifications procedure (ASEAN/MRA). This is a historical reference, not a single current price list for every foreign worker.

Check the current cost and whether it applies to your procedure. A visa’s validity period is not the same as permitted stay, and a visa payment does not replace the fee for the work permit.

By the way, the same amount does not yet mean the same procedure. The payment for the permit under the historical reference and the annual fee for the relevant categories of long-term residents (LTR) have different bases.

It is better to read the table from scope to amount. First determine the suitable route and permit period, then separate the application fee from the permit itself and from the visa part. Do not add all the lines into one overall budget: they describe different situations.

For your personal budget, discuss whether medical documents and support are needed and who will pay for them. The permit duration in the fee table does not show how long the application takes to review; plan the start date of work separately from calculating fees.

Companies with investment privileges (BOI): staff and salaries

Companies with investment privileges from the Board of Investment (BOI) have separate staffing conditions. These do not mean exemption from all requirements for personnel and do not become rules for an ordinary employer.

Requirement on the share of Thai workers at least 70% applies to manufacturing companies with an estimated headcount more than 100 workers. In the calculation, staff categories defined by the Board of Investment (BOI) are taken into account: this is not a universal quota for every company.

The official answers of the Board of Investment (BOI) to frequently asked questions give the following thresholds:

The reduced amount is a conditional threshold, not a free choice of the employer. The category must be matched to the position, education, and the conditions of the Board of Investment (BOI); these amounts cannot be used as a general minimum salary for a foreigner.

The wording of the education requirement is also important here. For management staff, a bachelor’s degree is specified, and for separately designated specialists, a relevant degree. Therefore, the discussion of the salary threshold should include classifying the position and matching education, not just the desired amount in the agreement.

Prohibited professions and the actual duties of a foreigner

Check the content of the work, not just the job title. A neutral job title does not answer whether all assigned tasks are permitted.

Before processing, discuss with the company:

• What exactly will you be doing?
• What restrictions and exceptions apply to this activity?
• Do the actual tasks correspond to the chosen procedure?
• Will a separate check be required if the duties change?

A Work Permit in Thailand should not be understood as a right to carry out any activity. When assessing an offer, rely on the restrictions that apply to specific tasks, not on a promise that “the documents cover everything.”

For a conversation with the employer, it is more useful to prepare a description of your duties in your own words than to rely on the job title alone. If the company proposes combining different tasks, each of them should be included in such a check. This is especially useful if the role changes after the application process.

Social security and salary conditions

The work permit, social security and taxes are separate matters. Getting a permit does not replace agreeing on the financial obligations of the employee and the company.

Before signing agreements, clarify with the employer:

• What salary conditions apply to your labor or immigration route?
• Do the special conditions of the Board of Investment (BOI) apply?
• How does the company handle social security?
• What contributions and tax issues should be taken into account when discussing income?

Do not apply the salary threshold of one special category to every foreign employee. It is more useful to discuss income together with the applicable contributions and taxes, while keeping the distinction between them.

Ask for the salary condition of the chosen procedure and the procedure for handling contributions to be explained separately. An answer that income is sufficient for one purpose does not yet resolve questions of social security or taxation.

A separate guide explains taxes for expats in Thailand. Here the goal is to understand which questions the company covers along with the employment paperwork and which need separate review.

Remote work: differences between the program (LTR) and the visa (DTV)

Remote employment does not make all visa routes the same. You need to distinguish the program category, the purpose of the visa and the nature of your activity.

The differences are described on the official LTR program page. The possibility of temporary work while a long-term resident (LTR) program application is under review cannot be transferred to the regular Non-B work visa route.

Distinguish separately between the provision for a category for which no permit is issued and the possibility of working temporarily while a permit application is under review. These are different grounds, so you cannot choose a suitable explanation based only on the word “remote”.

The annual fee for a work permit for the relevant categories of long-term residents (LTR) is 3,000 baht. It does not automatically apply to all program participants; more details are covered in conditions and obligations of LTR holders.

The consular fee for the DTV visa at the Thai Embassy in Washington is 400 US dollars. This is the mission’s visa fee, not the price of a work permit.

A visa’s purpose does not give the right to every kind of local activity or work with Thai clients. A separate article explains the purpose of the DTV visa for remote work.

Extension, dismissal and change of employer

After obtaining a work permit, track the employment paperwork and the basis of your stay separately. An extension of the work permit should not be considered an automatic extension of permitted stay in the country.

Changing employers in Thailand does not mean that a completely new permit is required in every case: the Department of Employment (DOE) portal provides a change procedure. But the existence of a form does not mean that the transfer has been completed.

Coordinate the actions of your current and new companies before starting the new job. BT.53 does not establish a grace period, a period for searching for a vacancy, or a universal deadline for departure after dismissal.

When changing jobs, it is useful to separate the end of the previous work, the processing of the new employer, and the check of your stay. Do not assume that the action of one company automatically closes all questions: determine in advance who is responsible for each part.

Separately check report on your place of residence. This obligation does not replace processing employment changes.

Responsibility of the worker and the employer

The worker and the company have different duties, so their responsibility should be assessed separately. It is important for the worker to have a basis for performing their tasks, and for the employer to correctly process the hiring and any subsequent changes.

For regular employment on a Non-B work visa, the Ministry of Foreign Affairs’ guidance is unambiguous: the permit must be obtained before work begins. A promise to complete the process after starting does not confirm that this requirement has been met.

Do not limit the check to whether the company has filed an application. Before starting work, you need to understand whether the necessary stage has been completed and whether the actual work matches the chosen basis. It is useful to discuss this together with the division of duties between the employee and the employer.

If work has already begun and the basis raises questions, review the specific situation with a lawyer specializing in this area: status, duties and the stage of processing matter. Possible legal consequences for the worker and the company require a separate assessment, without assumptions about identical sanctions in all cases.
