Most agencies stop at the paperwork. We run your accounting and tax too, so every visa renewal, work permit and audit lines up perfectly, year after year.

Your permit depends on company financials. We handle both, so renewals stay smooth.

100% compliant
Documents checked in detail to minimise rejections and keep you fully within Thai law.
The process
How a Chiang Mai work permit actually works
Five steps, in order. We take over from step three.
Get a Non-B visa
Apply for a Non-Immigrant B business visa at a Thai embassy in your country, or convert from a tourist or visa-exempt entry inside Thailand.
Enter Thailand on the Non-B
The Non-B lets you stay for business. On its own it does not give you the right to work — that comes next.
File at the Chiang Mai labour office
We submit your application and company documents to the Chiang Mai Provincial Employment Office on your behalf.
Wait for the review
The labour office reviews your file.

FAQ
Common questions from expats
Can I convert my tourist visa to a work visa in Chiang Mai?
Yes — in most cases we convert a tourist or visa-exempt entry to a Non-B business visa inside Thailand, then process your work permit. We handle the paperwork and appointments.
How long does a work permit in Chiang Mai take?
The labour office review takes 5 to 10 working days once your company documents are ready. We prepare everything in advance so nothing sends you back to the queue.
Do I need a Thai company to get a work permit?
Usually yes — you need a sponsoring employer. We can register your Thai company and sponsor the work permit in one package.
Can foreigners own 100% of a Thai business?
In specific cases — via BOI promotion, a US Amity Treaty company, or a Foreign Business License. We advise the best route for you.
