Working in Türkiye without a permit produces two consequences. The first is a fine, which is paid and forgotten. The second is a restriction code, which is not — it follows the person for years and defeats applications made long after the job ended. This article explains the Ç-117 code, what unauthorised work costs both worker and employer, and how the code is addressed.
What the code signifies
In administrative practice, the Ç-117 code is applied to foreign nationals found working in Türkiye without authorisation. It is associated with removal and with an entry restriction of a defined period — commonly described as one year, subject to the assessment in the individual case.
As always, classification and consequences are administrative rather than statutory, and the position in a particular case must be established by enquiry.
The framework
Work in Türkiye requires a permit under Law No. 6735 on International Labour Force, applied for by the employer, or an exemption that must be established rather than assumed.
The beliefs that most often lead people into difficulty are worth naming plainly, because each is wrong:
- "Part-time work does not need a permit." It does.
- "Unpaid or informal work does not count." It does.
- "A student residence permit allows part-time work." It allows an application for a work permit, subject to conditions.
- "A tourist visa allows a few days of work." It does not.
- "Owning the company means I can work in it." Ownership and work are separate; a limited company manager needs a permit.
- "Working online for a foreign employer while living here is unregulated." The position is unsettled rather than clearly permitted, and it should be assessed rather than assumed.
What it costs
For the worker: an administrative fine; a restriction code; cancellation of any residence permit; a possible removal decision and entry ban; and a record that affects every subsequent application — residence, work, family and, for an investor, the security screening in a citizenship file.
For the employer: substantially larger fines per unauthorised worker, increasing on repetition; liability for social security contributions that should have been paid; and liability for the worker's return costs. Employers who repeat the conduct face escalating consequences.
The asymmetry is worth noting: the employer pays more money, and the worker carries the durable consequence.
Where enforcement happens
Inspections by labour and social security authorities, checks in sectors where unauthorised work is common — construction, agriculture, hospitality, textiles, domestic work — cross-referencing of records, and reports. A worker's presence at a workplace during an inspection is frequently how the matter arises.
Payroll data is also visible: a person registered nowhere, working somewhere, is detectable from the absence rather than the presence of records.
Resolving the code
Establish what is recorded. A records enquiry through the migration authorities, made by a lawyer under a power of attorney if the person is abroad. Nothing sensible can be decided without it.
Pay outstanding fines. Unpaid amounts compound the position, and where the code is linked to a fine, settling it may assist.
Wait out a time-limited restriction, verifying expiry with the authorities rather than assuming a date.
Challenge it where the factual basis is disputed — for instance where the person was not in fact working, was carrying out an activity covered by an exemption, was a genuine volunteer, or was misidentified. An annulment action before the administrative court is the route, within the applicable time limit.
Apply for a visa with an annotation where entry is needed for a genuine, documented purpose during the restriction — including, notably, entry to take up employment for which a work permit has since been granted.
That last route deserves emphasis: where an employer has obtained a proper work permit, the annotated visa is the mechanism by which a person with a prior restriction can lawfully return to work.
If a removal decision has been issued
The deadlines govern everything:
- Seven days to apply to the administrative court against the removal decision; the person may not be removed during that period or while proceedings continue, unless they consent. The court decides within fifteen days and the decision is final.
- Where the person is in administrative detention, a separate application to the magistrate's court in criminal matters, decided within five days.
Nobody should sign a consent to voluntary departure without understanding that it removes the protection against removal during proceedings.
For employers
The compliance position is straightforward and is regularly ignored:
- Verify work authorisation before the person starts, not after an inspection.
- Where a permit is needed, the employer applies — the worker cannot.
- Register every employee with the social security institution.
- Where an exemption is relied on, identify the provision and obtain the confirmation where one is required.
- Track permit expiry dates; an expired permit is unauthorised work from the following day.
- Remember that the five-employee criterion compounds with each additional foreign hire.
Employers who take the risk knowingly should understand that they are also creating a durable record for the person they employed.
The investor dimension
A specific warning for anyone contemplating a citizenship investment. The security screening examines the applicant's immigration history, and a period of unauthorised work — however brief, however long ago — will surface there.
Discovered before the investment, it can be addressed while the investor still has options. Discovered afterwards, it leaves USD 400,000 committed and a file that cannot proceed until administrative or judicial proceedings conclude.
The records enquiry that establishes the position takes days. It belongs at the start of an investment file, not in the middle of one.
Frequently asked questions
How long does the restriction last? A defined period is associated with this code; establish the position for your case.
Does paying the fine remove the code? It settles the fine. It does not necessarily clear the record.
Can I return to work in Türkiye later? With a proper work permit and, where a restriction stands, an appropriately annotated visa.
Was my employer punished too? Employers face substantially larger fines and liability for contributions and return costs.
What if I was only helping out for a few days? Duration does not remove the requirement, though it may bear on the assessment.
What about remote work for a foreign employer? Unsettled. Take advice on your specific arrangement rather than assuming.
Will this stop my citizenship application? It will surface in the screening. Check and address it before investing.
Check first, work lawfully
Unauthorised work is the most common way a foreign national acquires a lasting problem in Türkiye, and it is nearly always the result of a misunderstanding rather than a decision. The fine ends the incident; the record does not.
