Frequently asked questions

What is the Thai-to-foreign staff ratio for a work permit?
The general rule is four Thai employees per foreign work permit, together with THB 2 million of paid-up registered capital per foreigner, reduced to THB 1 million and two Thai employees where the foreigner is married to a Thai national. BOI-promoted companies, representative offices and regional offices operate under different, generally lighter, requirements.
Can I start working while the work permit is being processed?
No — working before the permit is issued is an offence under the Foreigners' Working Management Emergency Decree, with fines of THB 5,000 to 50,000 for the worker and up to THB 400,000 per worker for the employer, plus possible deportation and a two-year ban on re-employment. Preparatory activities such as signing your own employment contract are not treated as work, but performing duties is.
How long does a work permit take to issue?
At the Department of Employment a complete application is typically issued within about seven to ten working days, and applications processed through the BOI One Stop Service Center can be completed far faster, sometimes within a day or two. The visa side runs in parallel: a Non-B visa or change of status must be in place before the permit is collected.
What happens to my work permit if I change employer?
The permit is tied to the employer, position and workplace, so a change requires a new application by the new employer and cancellation by the old one; you cannot simply transfer the booklet. After cancellation your permission to stay is normally shortened, so the new filing must be coordinated to avoid falling out of status.
