Who can sponsor a work permit for foreign employees?

Companies must meet certain conditions before hiring foreign employees.

These conditions include:

  • Officially registered in Thailand
  • Have applied for a tax ID and VAT registration
  • In the case of a Thai limited company with Thai majority ownership, must have a minimum paid-up capital of THB 2 million per foreign employee
  • For foreign majority ownership, must have a minimum paid-up capital of THB 3 million per foreign employee

How to apply for a work permit in Thailand?

Step 1: Securing a non-immigrant B visa

Before applying for a work permit, the foreigner must obtain a non-immigrant B visa from a Thai embassy or consulate in your home country. However, it is important to check with the embassy or consulate whether a WP.3 letter is also required or not.

WP.3 is a pre-approval system that needs to be completed by the employer in Thailand while the employee is out of the country. In some case, the applicant can only apply at an embassy or consulate within the country of their passport. You can read more about the WP.3 letter giving pre-approval of a work permit in our guide here.

The documents needed to obtain a non-immigrant B visa include:

  • An invitation letter from the employing company in Thailand signed by the company directors
  • A request from the company that the applicant shall be given a non-immigrant B visa so that the company can apply for a work permit for the applicant
  • Company attestation stating that the applicant is upstanding, law-abiding and guarantees that the employee will respect Thai culture and laws

You should apply for the non-immigrant B visa at least 30 days before travelling to Thailand. The consular officer may ask for copies of the company’s registration certificate and financial statements, which the company must issue.

Once the non-immigrant visa is secured, a temporary stay in Thailand for 90 days is allowed.

Step 2: Obtaining the work permit

The applicant must provide the following documents to apply for a work permit:

  • Work permit application form
  • Six photographs
  • Valid passport, copies of every page which each copy is signed by the applicant and:
    • For non-permanent residents – a non-immigrant visa
    • For permanent residents – a certificate of permanent residence and certificate of alien
  • Copy of education certificates and CV to prove the applicant’s educational qualifications
  • Recently issued medical certificate from a recognised hospital in Thailand showing that the applicant does not suffer from prohibited diseases:
    • Mental illnesses
    • Leprosy
    • Tuberculosis
    • Drug addiction
    • Alcoholism
    • Elephantiasis
    • Syphilis
  • Power of attorney to an agent if the foreigner does not submit the applicant himself
  • Signed copy of certificates or licenses (if any)
  • Marriage certificate (if married to a Thai national) and:
    • Thai spouse’s identification card
    • Birth certificate of children
    • Household registration

The Thai government may require applicants to have the above documents certified by the embassy and translated into the Thai language.

The employer must provide the following documents:

  • Commercial Registration Department certificate stating the name of the Managing Director and/or director, its objectives and registered capital
  • The shareholders list certified by the Commercial Registration Department
  • Factory license issued by the Factory Department, Ministry of Industry (if required)
  • VAT certificate
  • VAT filing
  • Withholding tax
  • Social security payment filing

The employing company must have four Thai employees per work permit.

Once the documents are submitted, it may take seven business days to issue the work permit.

For BOI companies, the process takes less than six hours to complete.

Upon issuance, the applicant will need to pick up the work permit in person at the Office of Foreign Workers Administration, Department of Employment of the Ministry of Labour.

Step 3: Tax ID card

While the work permit is being processed, the employer is required to apply for a Thai taxpayer identification card for the applicant at the Revenue Department.

The tax ID card contains the tax identification number (TIN), which will be used for documents that need the TIN.

Renewing a work permit

The stay visa must be renewed before renewing the work permit, which can be done inside or outside of Thailand. The work permit needs to be renewed before it expires.

The following documents are required when renewing a work permit:

  • Non-immigrant visa
  • Current work permit
  • Copy of your passport
  • Map of the company location
  • Copy of a medical certificate
  • Tax certificate showing that you are registered and has paid personal income tax in Thailand

Documents required from the employer include:

  • Copy of the registration certificate
  • Copy of VAT registration
  • Copy of the business license (if any)
  • Social security payment filing

Work permit restrictions

Once a work permit is granted, the foreigner must only work with the company specified in the work permit.

If the employee is assigned to another location of the company, it is required to obtain a new work permit covering the new location. The same applies to when the employee is going to work with another company.

In the case that the employee resigns or has been laid off by the company, the employee must return the work permit to the Labour Department within 10 days.

  • Foreigners entering to work under a BOI-promoted project (Investment Promotion Law) can start working while their work permit application is still pending. The work permit application must be submitted within 30 days after the approval of the BOI.
