Work Permit & Visa Lawyer in Chiang Rai — 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 Chiang Rai

Chiang Rai is Thailand's northernmost province, bordering both Myanmar and Laos. Trade through the Mae Sai, Chiang Saen, and Chiang Khong crossings — the latter on the 4th Thai-Lao Friendship Bridge — shapes the disputes that actually arise here: customs, cross-border sale contracts, debt recovery where the debtor sits in another jurisdiction, and land disputes across highland farming and tourism areas.

Suwanvara Law Firm has run border-trade and customs matters continuously from its Mekong-side base in the Northeast, so the procedures, paperwork, and workable lines of defence in this class of case are familiar ground. We work in Thai, English, and Chinese, run the file from our Khon Kaen head office and Bangkok branch, and travel to appear at the Chiang Rai Provincial Court as scheduled.

Frequently asked questions — work permit and visa lawyer in Chiang Rai

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.
