If you're in Thailand on a tourist visa and have been offered a job, you may be wondering how to convert your tourist visa into a work visa. While it’s possible, the process involves several steps and documentation.

Key Steps to Convert a Tourist Visa to a Work Visa:

1. Find a Job and Secure Sponsorship

  • You must have a job offer from a Thai company that is willing to sponsor your visa and apply for a work permit on your behalf.

2. Apply for a Non-Immigrant B Visa

  • A Non-Immigrant B Visa is required to legally work in Thailand. You can apply for this visa from within Thailand at an immigration office or by leaving Thailand and applying at a Thai embassy or consulate abroad.
  • Your employer will need to provide you with the necessary documents, including a job offer letter, company registration, and financial statements.

3. Work Permit Application

  • Once you have the Non-Immigrant B Visa, your employer can apply for a work permit from the Ministry of Labor. This process can take several weeks.
  • You will need your passport, medical certificate, employer’s documents, and a passport-sized photo.

4. Extension of Stay

  • After obtaining the work permit, you can apply for a visa extension, allowing you to stay in Thailand for up to 1 year, renewable annually.

Important Notes:

  • You cannot legally work on a tourist visa.
  • In most cases, it's easier to apply for the Non-Immigrant B Visa from outside Thailand.

By following these steps, you can smoothly transition from a tourist visa to a work visa and begin your employment in Thailand.

Can You Get a Work Permit on a Non-O Visa?

Only on two bases. A Non-Immigrant O held on the basis of marriage to a Thai spouse, or as the parent of a Thai child, allows the holder to apply for a Thai work permit. Every other Non-O category is not allowed to get one — that includes Non-O retirement, guardian of a foreign child, dependant of a Non-B work permit holder, and dependant of a retirement visa holder. The Non-OA and Non-OX retirement visas do not allow a work permit either.

On the two categories that do qualify, the visa and the work permit are independent of each other. The marriage or parent-of-Thai-child visa only allows the holder to apply for a work permit; it does not depend on one. If the holder stops working, they can cancel the work permit and keep the visa, provided they still meet that visa's financial requirement — typically 400,000 THB in savings at extension.

The employer requirements are lighter than on a Non-Immigrant B. A company sponsoring a work permit for a marriage or parent-of-Thai-child visa holder needs a ratio of 2 Thai employees per foreigner rather than 4:1, and 1,000,000 THB in registered share capital rather than 2,000,000 THB.

There is also an alternative to the savings test at extension: a valid Thai work permit plus 40,000 THB per month in income, evidenced with the PND 91 annual personal income tax return and PND 1 monthly withholding returns. The work permit alone is not sufficient — immigration needs the tax filings to verify the income.

As with any Thai work permit, it is tied to a single employer: the holder may only work for that one Thai company while the permit is active.
