Its geographic position and economic opportunities bring hundreds of thousands of foreign investors, skilled professionals and property buyers to Türkiye each year. In recent years, however, particularly as immigration policy has tightened over the 2024-2026 period, rejections of residence permit, work permit and exceptional citizenship applications have risen markedly, often because of a missing document or inadequate legal groundwork rather than any substantive shortcoming.
Drawing on our experience representing foreign investors and corporate expatriate executives before the Directorate General of Migration Management, the Ministry of Labour and the civil registry, we set out below the administrative pitfalls that most often lead to a file being refused.
1. Residence Permit Applications: Where Files Fail
Many applicants assume the process allows room for improvisation. It does not; it is a matter of documentary discipline.
Overstaying: The residence permit application should be made before the applicant's lawful period of stay expires, for example the 90 days available with or without a visa. Where the period is exceeded, an administrative fine is imposed, and the recorded breach adversely affects both the assessment of the current application and future entry requests; where the statutory conditions are met, a deportation decision under Law No. 6458 may also follow. This does not mean every overstay results automatically in deportation, but it puts the file in a weak position from the outset.Address registration: One of the most frequent grounds of refusal. Producing a lease is not enough. The lease should be notarised, the applicant should hold the electricity or water account in their own name, and the address should be registered with the civil registry in the Address-Based Population Registration System (ADNKS). Addresses that are not genuinely occupied, or that appear in someone else's name, are assessed unfavourably during address verification and can lead to refusal.Health insurance: Residence permits require a specific policy format designed for foreign nationals resident in Türkiye. Ordinary travel or standard health insurance does not meet the criteria under Law No. 6458 and results in the file being refused for incomplete documentation.2. Work Permits: The Employer's Test
Work permits are not issued by the migration authorities but by the Ministry of Labour and Social Security. In substance, the application tests the Turkish employer rather than the foreign national.
The five-to-one rule: At workplaces subject to balance sheet accounting, at least five Turkish citizens must be employed for each foreign national to be employed. That is the rule, but it is less absolute than commonly assumed, because of the exemptions set out below.Financial capacity thresholds (raised on 1 January 2025): There is a distinction here that most sources omit: the criteria differ for newly established and operating businesses:Newly established (incorporated in the current year, no year-end balance sheet yet): there is a single test, paid-in capital of at least TRY 500,000. No alternative is available.Operating businesses: paid-in capital of at least TRY 500,000, or net sales of at least TRY 8,000,000, or exports of at least USD 150,000. Any one of the three suffices.The earlier figures of TRY 100,000 in capital and TRY 800,000 in gross sales ceased to apply on 1 January 2025, and files prepared on that basis are refused. (The export threshold was already USD 150,000 and did not change.)
The exemptions that get missed: this is the critical part. The criteria contain broad exemptions, particularly on the technology and investment side, and in practice files are often closed as "below threshold" without these ever being considered:Information technology sector: for specialist roles such as software development, database, mobile software, systems/network/security and enterprise architecture expertise, neither the employment nor the financial capacity criteria apply at workplaces operating in the IT sector. Outside the IT sector the same exemption applies, limited to a maximum of two foreign nationals.R&D and technology zones: the employment and financial capacity criteria likewise do not apply to foreign nationals working as R&D, innovation or design personnel at companies holding an R&D Centre or Design Centre certificate, or working within a Technology Development Zone (the favourable opinion of the Ministry of Industry and Technology is required).Large turnover: at workplaces with net sales of TRY 50,000,000 or more in the previous year, the employment criterion is not applied for up to five foreign nationals.Foreign nationals with a track record in Türkiye: for those who have lawfully stayed in Türkiye for at least one year within the last three years under a work permit, residence permit or international protection, the employment and financial capacity criteria do not apply, limited to a maximum of three foreign nationals. (This exemption came into force on 3 August 2026 and is very recent.)A separate regime for foreign shareholders: A foreign national establishing or taking a stake in a business must satisfy three conditions together: the workplace must have paid-in capital of at least TRY 500,000, the foreign national's own capital contribution must be at least TRY 500,000, and their shareholding must be at least 20%. By contrast, these criteria do not apply to a foreign shareholder whose capital contribution is USD 100,000 or more. The five-employee requirement is also not applied immediately to a shareholder or business owner: the first work permit is issued with an annotation, and the employment condition takes effect from the beginning of the seventh month of that permit.Wage criterion: The wage payable to the foreign national is set as a multiple of the gross minimum wage: five times for senior executives and pilots, four times for engineers and architects, three times for other managers, twice for roles requiring expertise or craft skills, and not below the minimum wage for domestic services and other occupations.> Note: These criteria change frequently; during 2026 alone, new exemptions were added for the manufacturing, poultry farming and recycling sectors. The Ministry's current text should always be checked before filing.
Tax and social security debt: An employer with unpaid or unrestructured tax or social security liabilities cannot employ foreign nationals. The system blocks the file as soon as the debt appears.3. Citizenship by Investment: Thresholds and Red Lines
Acquiring Turkish citizenship on an exceptional basis (most commonly by purchasing real estate with a minimum value of USD 400,000, or by placing a bank deposit of USD 500,000) requires precision. A single incorrectly processed bank document can hold a file up for a long period.
The foreign currency purchase certificate (DAB): The investor cannot simply wire foreign currency to the seller. The regulations require the foreign currency to be sold to a bank in Türkiye and transferred to the Central Bank, with a Döviz Alım Belgesi issued in the buyer's name, and the Turkish lira equivalent then paid to the seller. A title deed transfer completed without following this process will not support a citizenship application.The valuation report: The figure that counts for the citizenship application is not the sale price on the title deed but the value determined in a report prepared by a valuer licensed by the Capital Markets Board (SPK). So long as the value in the report falls below the threshold, the application is refused: even if the deed shows USD 400,000, a report showing USD 390,000 will end the file. Inflated reports are not a solution either; valuation reports are subject to supervision by the Capital Markets Board, and findings that do not reflect reality invalidate both the report and the application.The three-year restriction: When the transaction is completed at the land registry, an annotation must be entered on the property recording that it will not be sold or transferred for three years. Without that annotation, the property gives rise to no citizenship entitlement, whatever its value.Document Chain: Apostille and Notarised Translation
No foreign document is accepted directly by Turkish authorities.
Birth certificates, marriage certificates, certificates of no impediment and similar documents must be certified in their country of origin with an apostille or by consular legalisation.Once in Türkiye they must be translated by a sworn translator and certified by a Turkish notary. A name rendered "Müler" instead of "Müller" in translation, or a keying error in a date of birth, will hold the application up for months.Challenging a Refusal
Where an application is finally refused, an annulment action must generally be filed before the administrative courts within 60 days of the decision being served on the applicant.
Immigration and citizenship practice changes frequently through circulars. This document is intended as general guidance and does not replace tailored legal advice.
