The employer is required to have a minimum registered capital of 2 THB million for hiring one foreigner.  So, if it wishes to hire 2 foreigners, it is required to have 4 THB million registered capital.

Ratio of Thai to Foreign Employees is 4:1 which means if the company wishes to hire 1 foreigner, it is required to hire 4 Thai employees.


If an American sets up a company (but he already has a work permit to work in Thailand or he doesn’t have to work in Thailand), the company will not be required to hire any Thai employees.
