Who must have a Work Permit?
The law requires all foreigners obtain a work permit before starting work in Thailand.
The foreigners having the following status do not need a work permit to perform their duty in Thailand:
1. Members of the diplomatic corps;
2. Members of consular missions;
3. Representatives of member countries and officials of the United Nations Organizations and specialized institutions;
4. Personal servants coming from abroad to work exclusively for persons listed in item (1), (2) or (3) above;
5. Persons who perform duties on missions in Thailand under an agreement between the Thai Government and a foreign Government or international organization;
6. Persons who enter Thailand for the purpose of performing any duty or mission for the benefit of education, culture, arts, or sports in Thailand;
7. Persons who are specially permitted by the Thai Government to enter and perform any duty or mission in Thailand.
1. Urgent and Essential Work:
Exemption from Work Permit requirements is granted to foreigners who enter the Kingdom temporarily but in accordance with the immigration law to perform any work of an “urgent and essential nature” for a period not exceeding fifteen days. However, such foreigners may engage in work only after a written notification on a prescribed form, signed by the foreigner and endorsed by his employer, has been submitted to and accepted by the Director-General or his assignee. The foreigners entitled to this treatment may enter Thailand with any kind of visa, including a transit Visa. The term “urgent and essential work” is not explicitly defined, and consequently, the issuance of this sort of exemption is a matter of administrative discretion.
2. Investment Promotion:
A foreigner seeking permission to work in the Kingdom under the Investment Promotion Law must submit his application for a Work Permit within thirty days from his entry into Thailand; if the foreigner is present in the Kingdom, the thirty-day period begins on the date he is granted permission to work under such law. A foreigner in this category may engage in the permitted work while his application is being processed by the authorities.

If the duration of employment of a foreigner is less than one year, a Work Permit will be granted for not longer than the period requested.
An authorized official may grant a Work Permit to a foreigner for a period that is necessary for the completion of work, but not longer than one year.
Other interesting points
The law prohibits employers from allowing foreign employees to perform any function other than that described in the foreigner’s Work Permit. The employers must report changes in employment, transfers and termination of all foreigners in their organization within 15 days. Failure to do so may result in a fine.
Work Permit holders must obtain a prior permission to change their occupation, and/or place of work.
Change of employer location or the residential address of the permit holder must be properly endorsed in the Work Permit by the labor authorities.
The Law does not prevent a foreigner from working in more than one field or for more than one employer. He has to have his Work Permit covering all the jobs or employers.
