Work Permit & Visa Lawyer in Chai Nat — 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 Chai Nat
Chai Nat is a rice and agriculture province in the Chao Phraya basin — home to the Chao Phraya Dam (the major barrage that distributes irrigation water across the Central plains), the Chai Nat Bird Park, and river logistics along the Chao Phraya, Noi, and Tha Chin rivers. Matters here often involve land, agriculture, irrigation water rights, rice and produce sale contracts, and civil, criminal, and family litigation. We handle land and inheritance disputes, business contracts, and general cases from our Bangkok branch.
Chai Nat is a Central-region province close to Bangkok, so our Bangkok branch (Lat Phrao) can attend court and coordinate with local agencies conveniently. As a firm with 40+ years' experience, we understand land and inheritance disputes across farming districts, irrigation water rights tied to the Chao Phraya Dam, and rice and produce sale contracts — with multilingual service for clients and investors, and we travel to provincial courts nationwide.
