How many Thai employees must a company have per foreign work permit?
Short answer
For an ordinary Thai limited company, the Department of Employment's practice is four Thai employees per foreign work permit, alongside a registered capital requirement of THB 2 million per foreigner. BOI-promoted companies and Treaty of Amity cases are assessed on different criteria.
Both tests are checked against evidence, not against the payroll spreadsheet. Officers look for the Thai employees to be registered with the Social Security Office and appearing in the monthly contribution filing, and for the registered capital to be fully paid up and reflected in the audited financial statements. A company that lists four staff but files social security for one should expect the application to be questioned.
The ratio is applied per foreigner, so a second work permit means a second set of Thai employees and a further tranche of paid-up capital. Where the ratio genuinely cannot be met, the realistic alternatives are BOI promotion, a Treaty of Amity structure for eligible US nationals, or restructuring the role so that the foreign national is engaged by an entity that already meets the test.
