Work Permit & Visa Lawyer in Chanthaburi — 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.

About our team in Chanthaburi
Chanthaburi runs two economies that generate their own disputes: a gem and jewellery market where high-value trades still rest on trust more than paperwork, and export orchards — durian above all — where Chinese packing houses and exporters buy at the grove. What follows is payment default, deposits, quality and grading disputes, and Cambodian border trade.
A trade done on trust is not an unenforceable trade — it means the case has to be built from the money trail, delivery records, and surrounding witnesses in place of the contract that does not exist. We have run this class of case for traders continuously. The team works in Thai, English, and Chinese, runs the file from our Khon Kaen head office and Bangkok branch, and travels to appear at the Chanthaburi Provincial Court.
