FAQ about Thai visa for business and work
You can apply for a 1-year or 3-year multiple-entry business visa which would allow you to travel to Thailand as frequently as you want while the visa remains valid, and you would be permitted to stay for a period of not exceeding 90 days on each visit.
You can find more information on the basic requirements for visa application at www.consular.go.th. To ensure that your application will be conveniently processed kindly check with the Royal Thai Embassy at www.thaiembassy.org/london.
In order to work in Thailand, there are 2 important elements:
(1) Non-Immigrant “B” Visa and
(2) Work Permit
First of all, you need to have a prospective employer in Thailand. Then you may apply for a Non-Immigrant Visa category “B” (business) at the Royal Thai Embassy in London or the Royal Thai Consulates in the United Kingdom using the basic required documents and recommendation letter from your employer along with your company’s business certifications as suggested in the website (www.consular.go.th).
Once you have obtained such visa, you can enter Thailand and therefore apply for a Work Permit from the Department of Employment, Ministry of Labour. In order to expedite visa issuance, your employer may, on your behalf, apply for the Work Permit in advance (with the form called Tor Thor 3). The Department of Employment will then issue a pre-approved certificate to be used in your visa application. In such case, please make sure to obtain the Work Permit (Tor Thor 2) once you arrive in Thailand.
