Work Permit & Visa Lawyer in Saraburi — 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 Saraburi

Saraburi is Thailand's cement and construction-materials base, and the land gateway every truck from the Northeast passes on the way into Bangkok. The legal work holds to three things: labor at the plants and quarries; contractor and materials-supply agreements, where the disputes are usually about progress payments and deductions; and land cases spanning farmland, project sites, and boundaries running up against concession areas.

Saraburi is within reach of both our Bangkok and Khon Kaen offices. On construction disputes we start by reading the progress-payment records and the full correspondence trail, because these cases turn on the order of the documents, not on testimony given afterwards.

Frequently asked questions — work permit and visa lawyer in Saraburi

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.

The Long-Term Resident (LTR) visa is a 10-year visa introduced to attract four target groups: wealthy global citizens, wealthy pensioners, work-from-Thailand professionals, and highly skilled professionals in BOI-targeted industries. Each category has income, asset, or insurance thresholds. The LTR is significantly easier to maintain than the traditional Non-B/Non-O routes (annual rather than 90-day reporting; digital work permit; simplified renewals). We assess fit and handle the application.

Voluntary departure with payment of the overstay fine at the airport is generally the simplest path for short overstays. Longer overstays (90+ days) trigger automatic re-entry bans (one year for 90 days, escalating up to 10 years for 5+ year overstays). If you've been arrested for overstay, you need representation before the immigration tribunal — call before you make any statement. We've handled both short fix-ups and longer custodial matters.
