Work Permit & Visa Lawyer in Khon Kaen — 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 Khon Kaen

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.
