Job Hunting and Changing Jobs in Thailand: Work Permit Transfers and Restricted Occupations
The Fundamental Rule: The Permit Belongs to the Job
A Thai work permit names a specific employer, position and workplace. Change employers and the permit must be redone, with the Non-B visa moving in step. That dictates the core logic of switching jobs in Thailand: line up the new employer's paperwork before touching the old. The baseline process is covered in our work visa guide; this article focuses on job hunting and transitions. Details follow current Labour Ministry and Immigration rules.
Where Foreigners Find Jobs
- Online: JobsDB and LinkedIn dominate white-collar hiring, JobThai skews local; foreigner-friendly roles cluster in sales, e-commerce, education, tourism and manufacturing management
- Recruiters: active in mid-to-senior roles and around Japanese and Chinese corporate communities; trilingual candidates command a premium
- Community referrals: chambers of commerce and industry groups convert well — but vet the company regardless, because a shell company cannot sponsor a work permit
- Vet the employer's capacity: sponsoring one foreigner conventionally requires 2 million THB registered capital and a 4:1 Thai-to-foreign staff ratio; asking about the current foreign staff's permits in the interview is entirely fair
Salary Talks: Immigration Has Benchmarks
Immigration applies monthly salary guidelines by nationality when extending work visas (commonly cited figures range from 25,000 to 50,000 THB depending on nationality group — verify current practice), and offers below your benchmark can complicate extensions. On package structure, know the local norms: a 13th month is not standard, provident funds vary by company, social security (SSO) is mandatory, and statutory annual leave is a minimum of six days. Employment rights are covered in our labor law guide.
The Right Sequence for Changing Jobs
- Secure the offer and confirm the new employer qualifies to sponsor
- Negotiate dates with both employers: when the old permit is canceled, the visa permission built on it ends too, leaving very little time to depart or convert status
- The safe pattern: new employer's application ready to file the moment the old permit is canceled; if the handover can't be seamless, exit, obtain a fresh Non-B abroad and re-enter
- BOI-promoted companies process through the One Stop Service Center — materially faster than the standard track
- On departure, settle taxes and collect your withholding certificate (50 Tawi) — needed for next year's filing and future fund repatriation; see our tax filing guide
The classic mistake: resigning in frustration and then starting the search. A status gap means visa runs or border bounces — far costlier than enduring another month or two.
Which Occupations Are Off-Limits?
The Labour Ministry maintains a list of occupations reserved for Thai nationals (historically 39 items, periodically revised). The ones that catch foreigners most often:
- Tour guiding (leading groups without a Thai guide license is illegal and actively enforced)
- Hairdressing, beauty services and Thai massage
- Manual labor, street vending and market stalls
- Legal services and court representation (Thai lawyers appear in court)
- Signing audits as an accountant (management roles are fine; licensed sign-off is not)
Beyond the list, your actual duties must match the permit: registered as "marketing manager" while leading tours daily is still illegal work.
Freelancing and Remote Work: Where Is the Line?
- Providing paid services to local clients without a work permit is illegal work — side gigs, buying-agent operations and brokering included — punishable by fines, detention and deportation with a record
- Remote work for overseas employers on visas like the DTV is the sanctioned direction, but employment by a Thai entity or serving the Thai market is outside it; get advice on edge cases before acting
- The compliant solo routes: register a Thai company to sponsor your own permit (costs in our company registration guide) or use a reputable employer-of-record — vetting the EOR's own compliance carefully
FAQ
If I'm laid off, does my visa die immediately?
When the work permit is canceled, the visa permission tied to it ends without a generous grace period. Confirm the cancellation date with HR immediately and plan in parallel: convert to a tourist status, exit, or have the new employer expedite. Statutory severance scales with tenure — verify full payment before signing anything; see the labor law guide.
Can I start working while the permit is still in process?
No. Working before issuance is illegal work, with penalties for you and the employer. Legitimate companies schedule start dates after approval; an employer saying "start now, we'll sort the permit later" is itself a red flag.
Does helping a friend's shop or livestream selling on weekends count as illegal work?
Very likely yes. Thai law doesn't make payment the sole test of "work" — sustained labor can qualify, and publicly visible activities like livestream selling are especially exposed to reports. Don't gamble residence status on pocket money.
