Foreign nationals who have worked in Türkiye for years on employer-sponsored permits reach a point where the arrangement starts to constrain them. The permit is tied to one company; changing jobs means a new application; a redundancy is an immigration event as well as an employment one. The indefinite work permit removes that dependency. This article explains what Law No. 6735 requires and how the route compares with the alternatives.
The requirement
Law No. 6735 on International Labour Force provides for an indefinite work permit (süresiz çalışma izni) for foreign nationals who hold a long-term residence permit, or who have had a lawful work permit for at least eight years, subject to the conditions determined in the legislation.
The application is assessed against those conditions and against the applicant's record, and the resulting permit is not tied to an employer or a period.
Where "eight years" gets complicated
As with long-term residence, the arithmetic is stricter than it looks.
The permits must be lawful and continuous. Gaps between permits — a period between leaving one employer and starting with another during which no permit was held — undermine continuity. Whether a particular gap is fatal depends on its length and circumstances, but the safe assumption is that gaps are damaging.
Periods without a permit do not count, including periods when the person was in Türkiye on a residence permit but not working, or working without authorisation.
Time on other bases does not automatically count. The requirement is a work permit, and time spent on a student permit or a family residence permit without a work permit is not the same thing.
Anyone contemplating this route should have their permit history reviewed before applying rather than discovering a gap in the assessment.
The other conditions
- Clean criminal record, evidenced by a certificate.
- No outstanding tax or social security debts — a condition worth checking early, because historic liabilities from a previous employment or a company can surface unexpectedly.
- Sufficient and regular income, evidenced over a period rather than at a moment.
- Health insurance or social security cover.
- No threat to public order or public security.
The tax and social security condition is the one most frequently underestimated. A person who was a shareholder or manager of a company that ceased trading with unpaid liabilities may carry personal exposure for those debts — particularly in a limited company — and an unresolved amount can defeat the application.
What the permit gives
- The right to work without an employer sponsor, and to change employers freely, subject to the rules applying to regulated professions.
- Indefinite duration, with no renewal cycle.
- Residence rights for its duration.
- Rights broadly comparable to those of Turkish citizens in defined areas — with the same familiar exclusions: no political rights, no eligibility for public posts reserved to citizens, no exemption from military service obligations where they apply, and no duty-free vehicle import.
The practical value is the removal of dependency. An employee whose immigration status rests on a single employer is in a materially weaker position than one whose does not, and that difference shows up in employment negotiations as well as in emergencies.
Comparing the three long-term routes
| Indefinite work permit | Long-term residence | Naturalisation | |
|---|---|---|---|
| Qualifying period | 8 years of work permits | 8 years of residence permits | 5 years of residence |
| Language requirement | None | None | Adequate Turkish |
| Employer needed | No | Not applicable | Not applicable |
| Passport | No | No | Yes |
| Political rights | No | No | Yes |
| Can be lost | Yes, in defined circumstances | Yes, including a year's absence | Only in narrow cases |
A person who has held work permits for eight years has usually also held residence permits for the same period, and may therefore qualify for both the indefinite work permit and long-term residence. Where naturalisation is realistic — five years of residence and adequate Turkish — it is generally the stronger outcome, because it ends the question permanently.
The routes are not mutually exclusive, and the right choice depends on the applicant's language ability, their attitude to citizenship, and any restriction in their own country's law on holding a second nationality.
Losing it
An indefinite permit can be cancelled — where it was obtained on false information, where public order or security grounds arise, or where the holder remains outside Türkiye for an extended period without a recognised reason.
That last ground mirrors the long-term residence position and catches people in the same way: a long assignment abroad, an extended family obligation, a return home that becomes permanent by accident. Where an absence of a year or more is contemplated, take advice before leaving.
If the application is refused
A refusal is an administrative act, challengeable by annulment action before the administrative court within sixty days of notification.
Refusals on continuity grounds turn on the permit record and are met with evidence: permit cards, employer records, social security records establishing the employment history. Refusals on tax or social security grounds are usually better addressed by resolving the underlying debt than by litigating about it.
Preparing for the application
- Assemble every work permit and residence permit card held over the eight years.
- Obtain social security records showing the employment history without gaps.
- Check for outstanding tax or social security liabilities, including any arising from a company you held an interest in.
- Obtain a criminal record certificate.
- Assemble income evidence over a period — payslips, tax records, bank statements.
- Confirm health insurance or social security cover is current.
- Have the permit history reviewed for gaps before applying.
Frequently asked questions
Does time on a student permit count? The requirement is work permits. Take advice on your specific history.
Do short gaps between employers break continuity? Potentially. Have the history reviewed.
Can I change jobs freely afterwards? Yes, subject to the rules applying to regulated professions.
Is there a language requirement? No.
Does it lead to citizenship? It is a separate status. Naturalisation has its own conditions.
Can I start a business on it? Working independently is within its scope, subject to the applicable professional rules.
What if I leave Türkiye for a year? An extended absence can lead to cancellation. Take advice before a long departure.
Reviewing the record first
Applications on this route are decided largely on a record that already exists and cannot be changed. The useful work is establishing what that record shows — permits, gaps, contributions, liabilities — before an application is made rather than after a refusal.
