In-Depth Guide: Change of Employer (WP-Change-Emp)

Change of Employer is delivered under ILC's Thailand Work Permit and Foreign Business Licence — Full Guide practice, combining MoJ-certified translation, MFA legalization, embassy liaison, and Thai government filing under one project manager. Every case is handled by a NAATI-accredited translator, a Thai Notarial Services Attorney, and a dedicated case coordinator.

A Thai work permit (Tor Tor 3) is a statutory prerequisite for any foreign national engaging in remunerated activity inside Thailand, whether as an employee, executive, consultant, or shareholder-director. Beyond the standard Ministry of Labor route, ILC supports the specialised regimes that dominate modern practice: Board of Investment (BOI) fast-track single-window approvals at the OSOS building, IEAT permits inside industrial estates, Smart Visa for executives, technology experts and startups, Long-Term Resident (LTR) visa, DTV Destination-Thailand digital-nomad visa, and Foreign Business Licence (FBL) or Foreign Business Certificate (FBC) filings under the Foreign Business Act B.E. 2542. Each path has distinct minimum-capital rules (2M/3M/5M THB), Thai-to-foreign employee ratios (4:1 general, waived for BOI and Smart Visa), work-scope definitions, and renewal windows. Missing a single detail — for example a job description that overlaps with a Restricted Occupation List item — is grounds for rejection or a THB 100,000 fine.

Why choose ILC for Change of Employer

With more than 15 years of practice, ILC covers every embassy in Bangkok and both MFA offices (Chaengwattana and Chiang Mai). We operate a two-tier QA review and refund the service fee if a document is rejected due to a defect in our translation or certification — government fees and officer discretion excluded.

How Change of Employer is Processed

The workflow below reflects current 2025–2026 practice with the relevant Thai authority and factors in queue seasonality, translation dependencies, and cross-agency handoffs.

1) Route selection
We map the applicant's role, salary and shareholding to the most efficient route (Ministry of Labor, BOI, Smart Visa, LTR, DTV).
2) Corporate and financial preparation
Company registration, capital paid-up evidence, tax filings and social security registration are readied to meet the underlying test.
3) Visa alignment
Non-B, LTR, or Smart-Visa entry is coordinated with immigration so work-permit filing occurs within statutory windows.
4) Ministry filing
Application, contract, and supporting documents are lodged at the appropriate desk (One Stop, OSOS, or DoE).
5) Approval and card issuance
Blue book (traditional) or digital work permit card is issued, typically within 7 working days for BOI and 15 days for standard filings.
6) Annual renewals and reporting
90-day reports, tax filings, and annual permit renewal are handled proactively to avoid overstay or lapse penalties.

Documents & Requirements for Change of Employer

The checklist below covers standard files. Complex or corporate matters can add supplementary certificates, board resolutions, or notarised affidavits; ILC brief these during the intake call.

Passport with valid non-immigrant B or eligible category
Employment contract with detailed job scope
Company registration, tax and social security certificates
Degree and CV of applicant
Health certificate (Form Tor 5) issued within 30 days
Photograph 3×4 cm, business attire

Smart Visa / LTR	Multi-year, family included, no Tor Tor 3 needed for some categories	Requires minimum salary or investment thresholds

FAQs about Change of Employer

คำถามที่พบบ่อย

Can I start work before the permit is issued?

No. Any remunerated activity before the card is printed is a criminal offence carrying a THB 5,000–50,000 fine.

Is a remote worker for a foreign company required to hold a permit?

Yes if work is performed physically in Thailand; the DTV visa now provides a compliant pathway for many freelancers.

How fast can BOI approval be secured?

Typical BOI application: 40–60 working days; work-permit issuance after promotion: 5 working days at OSOS.

Can dependents work?

Only if they hold their own work permit; the family visa alone does not grant work rights.

A working guide to Work Permit Thailand in Thailand

Work Permit Thailand is one of the standing service lines that corporate legal departments, embassies, foreign universities, HR compliance teams, and immigration bureaux route their highest-stakes files to. The institutional posture — as opposed to a freelance translator or a generalist firm — is the deliberate reason receiving offices treat the deliverable as finished, not draft. Every Work Permit Thailand matter is scoped by a senior specialist on LINE Official @NAATI or by email at ilc@thainotary.co.th before any file moves.

How the workflow runs end-to-end

For matters that touch multiple counters — Amphur District Office, DBD, DIP, BOI One Stop, or the Criminal Records Division of the Royal Thai Police — a dedicated runner sequences the visits in the correct legal order, so the client is not sent from one office to another chasing missing signatures.

Who this service is for

Foreign missions in Bangkok and international bodies on framework contracts receive a dedicated key-account manager, standardised invoicing on 30-day net terms, and monthly consolidated statements that meet their internal audit format — no bespoke translation project management on their side.

Coverage, fees, and turnaround

Same-day express is offered for filings tied to a flight, hearing, or academic deadline, subject to counter availability at MFA Chaeng Watthana and the destination embassy. The surcharge is quoted before work begins and is not applied retroactively.

Quality assurance and confidentiality

Every certified translation ships with a translator's declaration on our headed paper carrying the linguist's full name, credential number, and dated signature — the format immigration officers, university registrars, and consular staff are trained to accept without follow-up questions.

One step out of order usually means restarting the whole bundle. More than 15 years of cross-border document work means we recognise how each authority rejects files and prevent it up front.

The certification route is matched to the receiving authority before work begins.
Rejection risks are checked, from name spelling to document validity windows.
The filing sequence is planned around the deadline you actually have.
