Work Permit & Visa Lawyer in Bangkok — Non-B, Non-O, LTR, BOI Smart Visa, 90-Day Reports

Thailand's immigration regime ties three things tightly together: the visa (Non-B for work, Non-O for marriage/retirement, LTR for long-term residents, Smart Visa for BOI-promoted talent), the work permit (issued separately by the Ministry of Labour and only valid for the specific employer and role on the permit), and the 90-day report (required of all foreigners staying continuously for 90 days or more). Getting any one wrong invalidates the others. We handle the full application chain, the renewals, and — when things go wrong — overstay resolution and appeals against denied applications.

Frequently asked questions — work permit and visa lawyer in Bangkok

3 questions answered

No. It is an offence to work in Thailand without a valid work permit, even if your visa allows residence. "Work" is interpreted broadly under the Working of Aliens Act — it includes unpaid work, signing contracts on behalf of an employer, and attending business meetings in some circumstances. We help time the application so there is no working gap.
