On the 10th of May 2018, the Department of Employment (DoE) has
published a letter to address the scope of the Work Permit under
the Emergency Decree on Foreign Employee Management B.E. 2561 (the
"Decree 2018"). It especially elucidated the question
whether a foreigner who has been granted a Work Permit once is able
to work in another type of work, for another employer, at another
workplace or work condition in Thailand.
Section 70 of the Emergency Decree on Foreign Employee
Management B.E. 2560 (the "Decree 2017) has been repealed
through the Decree 2018 and, therefore, the application form TM.6
has been revoked, neither the employer nor the employee has to
register any changes related to the type of work, the employer,
workplace or work condition any longer.
