The Permit Is Not the Person: What a Fang District Case Tells Employers About Who Carries the Risk

A post shared by Duncan Riley in the Chiang Mai News in English group on 18 August set out the details of a joint operation by Chiang Mai Provincial Immigration and the Provincial Employment Office in Wiang subdistrict, Fang district. Acting on a tip-off, officers inspected a business premises and arrested two Myanmar nationals. Both held valid permission to remain in Thailand. Both held valid work permits, listing their job type as labourer. Neither had told the registrar that they had changed employer. According to the report, they had been working at the premises for around five months, clearing tables, washing dishes and serving food, for 300 baht a day.

On the surface, this looks like an immigration story. But read it properly, and it is in fact a compliance story. Where the compliance failure belongs mostly to the business that employed them.

Why “they already had a permit” is not the same as “they were legal to work there”

A Thai work permit is not a general licence to work. It is issued against a specific employer and a specific job, and it records the province where that employer operates. Section 20 of the Alien Working Act sets out these particulars: the employer, the nature of the work, and the area in which it is carried out. Move to a different employer, take on a different role, or work in a different province, and the permit as issued no longer covers you, even if it has not expired and even if your visa status is otherwise in order.

This does not mean the permit pins you to one street address. A landscaping crew, a cleaning contractor’s team, or a construction gang, moving between client sites every day under the same employer and the same job description, is working exactly as the permit describes. What the law tracks is who you work for and what you do, not which garden you happen to be standing in on a given afternoon.

This is the point that gets missed by both sides. The worker assumes that holding a permit at all means they are covered. The employer assumes that hiring someone who already has a permit removes the need to check anything further. Both assumptions are wrong, and the law places a duty on both parties to correct the record.

The two routes into legal employment, and why they are often confused

Foreign workers in Thailand generally arrive at a legal work status through one of two structures.

The standard work permit route, usually paired with a Non-Immigrant B visa, applies to professional and skilled hires and is the structure most familiar to foreign-owned SMEs. The permit is issued against a specific company, role and salary threshold.

The MOU route applies to Myanmar, Lao and Cambodian nationals brought in under the bilateral labour agreements between Thailand and those countries. This is a separate administrative pathway with its own quota and registration process, and it is the route that covers the great majority of migrant labour in food service, agriculture, construction and light manufacturing in Chiang Mai. An MOU worker is registered to a specific employer in the same way as a Non-B holder. The mechanism is different. The obligation is the same.

The obligations, set out by party

The worker’s duty. Under the Alien Working Act and the 2017 Royal Ordinance on Management of Employment of Foreign Workers, a permit holder who changes employer, changes job, or changes work location must notify the registrar within 15 days. Failing to do so is itself an offence, separate from the question of whether the new job would otherwise have been permitted.

The employer’s duty. The obligation is not one-sided. An employer taking on a foreign worker, including one who already holds a permit issued for another employer, must notify the Department of Employment within 15 days of the hire, and must notify again if the person’s employment ends, for any reason. The employer also carries a duty under Section 14 to ensure the work the person actually performs matches what is stated on the permit. A mismatch between the job on paper and the job on the floor is a compliance failure attributable to the business, not the worker.

What it costs when it goes wrong, by tier

The consequences scale with the nature of the breach, and employers should understand the tiers rather than treat this as a single flat risk.

Notification failure alone (permit valid, correct role, but the registrar was never told of the change) draws an administrative fine, generally up to 20,000 baht, applied to the worker, the employer, or both.

Employing outside the scope of the permit (wrong role, wrong site, or an MOU worker used outside their registered employer) escalates the exposure. Reported penalty ranges for employers here run from 10,000 to 100,000 baht per worker on a first offence, rising to imprisonment of up to one year and fines between 50,000 and 200,000 baht per worker on repeat offences, together with a three-year prohibition on the business employing any foreign national. Some recent commentary on 2025 to 2026 enforcement puts the ceiling for aggravated cases considerably higher. The exact figure that applies depends on which section is engaged and whether the Department of Employment treats it as a first or repeat matter, which is a question for the facts of each case rather than a fixed number.

For the worker, the consequences sit outside the fine schedule entirely. Detention, prosecution, and deportation are the practical outcome, and a criminal record from this kind of case can close the door to future legal work in Thailand. The business absorbs a fine and a compliance headache. The worker absorbs the loss of their livelihood and, often, their ability to return.

The point most employers miss: your own status can be tied to theirs

If the employer, or a director or shareholder of the employing company, is themselves a foreign national holding a Non-B visa through that same business, the exposure does not stop at the fines above. A company’s right to sponsor and employ foreign workers is what a foreign director’s own Non-B extension typically rests on, alongside the usual capital, staffing ratio and active operation requirements. Where the Department of Employment suspends a company’s right to employ foreign nationals, or imposes the three-year prohibition that follows a repeat scope violation, the foundation supporting that director’s own visa extension is directly undermined. 

A business that gets careless about a dishwasher’s paperwork can end up putting its own foreign owner’s legal basis to remain in the country at risk. This is rarely how the exposure is explained to SME owners, and it should be.

What “properly linked” means in practice

The standard is not complicated, and it does not require legal training to apply consistently.

Every foreign worker on the payroll, MOU or Non-B, should be checked against three questions: is the employer named on their permit this business, is the role stated on their permit the role they are actually doing, and is the province stated on their permit the province they are actually working in. Any change to any of those three answers triggers a 15-day notification window, and it is the employer’s job to start that process, not to wait for the worker to raise it. An existing permit from a previous job is not a shortcut. It is the starting point for a fresh registration, not a substitute for one.

There is aother check that sits before all three of these, and it is the one businesses often miss. The company’s registered business objectives, filed when it was set up, must support the job being sponsored. A mismatch here is where many applications stall, since Labour and Immigration do not always accept the same fix as sufficient, and a business can satisfy one only to be told by the other that the file is still incomplete.

None of this is difficult to build into a standard onboarding checklist. What it requires is treating a foreign worker’s paperwork as a live compliance record that changes when their circumstances change, rather than a document that is checked once at the point of hire and then filed away.

The standard this should be judged against

The Fang case will likely be filed away as a minor immigration story about two dishwashers. It should not be. It is a clean illustration of a system where the paperwork failure sits with the employer as much as the worker, but the consequences fall almost entirely on the worker. An employer who hires someone already holding a permit, puts them to work without updating the registration, and leaves them exposed for five months has not saved themselves an administrative step. They have transferred the entire risk of that shortcut onto the person with the least power to absorb it.

Getting this right is not a matter of avoiding an inspection. It is a matter of not building a business on the assumption that someone else’s paperwork problem is not yours to fix.
