Changing Jobs Requires a New Work Permit?
Yes, every time you change employer in Thailand, you need a new work permit. A Thai work permit is issued for one employer, one job title, and one work location. It is not transferable. When you leave a job, the old permit must be cancelled with the Department of Employment, and your new employer must sponsor a fresh application before you perform any duties for them.
At Thai Visa Centre in Bangkok, we coordinate work permit changes with HR teams every week. Skipping this step, even for a few days of overlap, exposes you and your new employer to fines and visa problems.

What happens when you leave your job
When employment ends, resignation, termination, or contract expiry, the standard sequence is:
|------|-----|--------|
You cannot legally work for the new company until the new permit is approved, even if you still hold a valid Non-Immigrant B stamp.
| Step | Who | Action |
|---|---|---|
| 1 | Former employer | Cancels work permit at Department of Employment |
| 2 | Former employer | Returns permit card; updates TM30 if applicable |
| 3 | You | Confirm visa status. B visa may remain valid briefly without active permit |
| 4 | New employer | Prepares company documents and sponsors new permit |
| 5 | You | Wait for approval before starting the new role |
| 6 | Immigration | Extends or updates visa to match new permit validity |
Why a new permit is mandatory
Thai labour law treats the work permit as a contract between you, your employer, and the government. The document lists:
Working for a different company on an old permit is illegal, even if your visa category (Non-Immigrant B) is still valid.
- Employer name and registration
- Position and job description
- Approved workplace address
Visa status after a job change
Your visa and work permit are linked but not identical:
Some holders switch to Non-Immigrant O (marriage or other basis) if they no longer qualify for B, plan before your permit gap grows too long.
- Work permit cancelled, you lose legal right to work immediately
- Non-Immigrant B visa, may remain valid for a short period, but working without a permit still violates labour law
- One-year extension tied to old employer, immigration may require re-extension with new employer documents

Common mistakes
Work through these named steps in order where they apply to your situation. Skipping document legalisation, TM30 registration, or re-entry permits is a common reason applications fail at immigration.
Step 1
Assuming a valid B visa lets you start a new job without a new permit
Letting the old employer delay cancellation
Letting the old employer delay cancellation, blocks the new application
Teaching or consulting informally during the gap
Teaching or consulting informally during the gap, still counts as work
Forgetting 90
Forgetting 90-day reporting and TM30 updates during employer change
Step 5
Changing job title or location within the same company without amending the permit
For 90-day reporting help, see 90day.in.th. For entry requirements, see Thailand entry requirements.
Before you travel or file
Use this checklist alongside the steps above. Most rejections we see at Bangkok immigration come from missing one item on this list rather than from the main visa rule itself.
- Download the current checklist from thaievisa.go.th for your nationality and visa category. Lists change without wide announcement.
- Complete TDAC within 72 hours before every flight, train, or land crossing into Thailand.
- Carry printed copies of embassy letters, insurance certificates, and financial proof, not phone screenshots alone.
- Confirm your passport has enough blank pages and validity for the full intended stay plus buffer days.
- Book embassy or district office appointments before you fly if your nationality requires in-country processing in Bangkok.
- Set calendar reminders for 90-day reporting, extension expiry, and re-entry permit dates before you leave on holiday.
Who this guide is for
This FAQ is written for foreign nationals planning travel, registration, or long-stay compliance in Thailand. The answer may differ if you hold a Thai passport, diplomatic status, or a work permit tied to a BOI-promoted company.
Short-stay tourists
Verify visa exemption or VOA eligibility, complete TDAC, and carry travel insurance even when not mandatory. Hospitals expect payment or cover before major treatment.
Long-stay visa holders
Track TM30, 90-day reporting, annual extensions, and re-entry permits. Privilege and LTR tiers may simplify some reporting but never remove TDAC or overstay rules.
Couples and families
Marriage registration at a district office is separate from ceremonies and from marriage visa applications afterward. Plan embassy documents and MFA legalisation before you book wedding venues.
Workers and employers
A B visa alone does not authorise work. Every employer change requires a new work permit. Remote work for foreign employers on tourist stamps remains high risk at immigration.
Compliance reminders
Thailand is welcoming when your paperwork matches your behaviour. These habits apply across most visa categories, whether you are visiting for two weeks or renewing a one-year marriage extension.
- Complete TDAC within 72 hours of every landing, including returns after holidays abroad.
- Confirm your landlord or hotel files TM30 address notification within 24 hours of check-in.
- File 90-day TM47 reports when you remain in Thailand 90 consecutive days without departing.
- Obtain a re-entry permit before leaving if you hold a single-entry visa with a valid extension.
- Match your visa category to your activity. Tourism stamps do not authorise employment in Thailand.

Frequently asked questions
General answers for planning purposes. Confirm specifics with official sources or our team before you travel.
Q:Can I keep my old work permit until the new one is ready?
A:No. Only one active permit at a time. The old employer must cancel before or as the new application proceeds.
Q:Does a Smart Visa or BOI permit work differently?
A:Approved Smart Visa and BOI routes bundle work rights, employer changes still require notification and updates to immigration. See /guides/thailand-smart-visa.
Q:What if I am fired and have no new job?
A:Your permit is cancelled. You must find a new sponsor quickly or change visa category before your lawful stay expires.
Q:Can my spouse's marriage visa cover me while between jobs?
A:A marriage visa does not grant work rights. You still need your own permit for employment.
Q:When was this guide last reviewed?
A:June 2026. Immigration and embassy rules change without notice. Verify on official sources before you travel, extend, or register.
Q:Can Thai Visa Centre handle this for me?
A:Our Bangkok team prepares embassy documents, files TM47 90-day reports, coordinates district office marriage registration, and manages extension season paperwork. Book an appointment or start live chat for a document review.
Q:Does this FAQ replace legal or immigration advice?
A:No. This page is general orientation for planning. Your nationality, visa history, finances, and employer structure may change the correct answer. Confirm specifics before you book non-refundable flights or sign a lease.
