Can a foreigner take legal action when a Turkish citizenship security investigation remains pending for years? Learn about administrative petitions, prolonged inactivity, administrative court remedies and citizenship application delays in Turkey.

A Turkish citizenship application can remain under security, archive or public-order examination for a substantial period. However, an applicant whose file appears to remain indefinitely at the same stage should not necessarily assume that there is no legal remedy.

National security and public order are expressly relevant to several routes for acquiring Turkish citizenship. For example, they are statutory considerations for citizenship under the general rules and exceptional citizenship.

This means that a security investigation can legitimately form part of the citizenship process.

However, a legitimate investigation and indefinite administrative inactivity are not necessarily the same thing.

Depending on the procedural history, a foreign applicant may consider formal administrative applications and, where the legal requirements are satisfied, proceedings before the administrative courts.

The important distinction is this:

Legal action concerning an excessively delayed citizenship investigation does not automatically create a right to Turkish citizenship.

The issue is generally whether the administration has lawfully processed and concluded the application.

Is a Security Investigation Normal in a Turkish Citizenship Application?

Yes, depending on the citizenship category.

Turkish citizenship legislation makes national security and public order relevant to several citizenship routes.

For general naturalization, one of the statutory requirements is that the applicant must not have a condition constituting an obstacle in terms of national security and public order.

Exceptional citizenship is likewise subject to national-security and public-order assessment.

Official administrative guidance also specifically refers to obtaining a security investigation when processing certain exceptional citizenship applications.

Therefore, merely seeing that a file is undergoing security examination does not mean that something is wrong.

Does a Security Investigation Mean the Application Will Be Rejected?

No.

A pending security investigation is not the same as a citizenship rejection.

Applicants should distinguish between:

• An application still being investigated;
• An application awaiting information from another authority;
• An application undergoing final evaluation;
• An application that has actually received a negative decision.

Until a formal decision has been made, the applicant should not automatically treat a prolonged security stage as an unofficial rejection.

How Long Can a Citizenship Security Investigation Take?

There is no universal publicly stated timetable guaranteeing that every citizenship security investigation will be completed within a particular number of months.

The official citizenship system allows applicants to check the general status of their application using the application number and date of birth.

However, the official status system does not provide a fixed timetable for every internal security or administrative examination.

Consequently, claims such as:

“Security investigation must finish within three months,”

or

“After six months the application is automatically approved,”

should be treated cautiously.

Is One Year of Security Investigation Automatically Unlawful?

Not necessarily.

The passage of one year alone does not automatically establish unlawful administrative conduct.

The complete procedural history matters.

Relevant questions include:

• When was the citizenship application submitted?
• When did the security examination begin?
• Has the application status changed?
• Were additional documents requested?
• Did the applicant provide all requested documents?
• Is there a known criminal or immigration issue?
• Have the authorities requested updated identity information?
• Has the applicant submitted a formal petition?
• Has the administration responded?

A legal assessment should be based on this chronology rather than the duration alone.

What If the Security Investigation Has Taken Two or Three Years?

A multi-year investigation deserves closer examination.

This is particularly true where:

• The applicant has supplied every requested document;
• No additional documentation has been requested;
• The application remains at substantially the same stage;
• No substantive explanation has been provided;
• Formal inquiries produce no meaningful result.

The applicant may then need to move beyond repeatedly checking the online application status and create a formal administrative record.

What Should the Applicant Do Before Filing a Lawsuit?

The first step should generally be to establish exactly what has happened to the citizenship application.

The applicant should collect:

1. Citizenship application number;
2. Original application date;
3. Citizenship category;
4. Copies of submitted documents;
5. Previous status records;
6. Dates of important status changes;
7. Additional document requests;
8. Responses submitted to the authorities;
9. Previous petitions;
10. Administrative responses.

This chronology can become critical if judicial review is later considered.

Can the Applicant Submit a Formal Petition?

Yes.

Where a citizenship application has remained unresolved for an unusually long period, a formal written application to the competent administrative authority may be appropriate.

The petition can request information concerning the application and completion of the pending administrative process.

It should normally identify:

• Applicant’s full identity;
• Application number;
• Application date;
• Citizenship category;
• Current application status;
• Duration of the security examination;
• Previous correspondence;
• Relevant changes in circumstances;
• Request for completion of the procedure.

Proof of submission should be preserved.

Why Is a Formal Petition Important?

A formal petition can serve two purposes.

First, it gives the administration an opportunity to examine and address the prolonged delay.

Second, it creates a documented procedural event that may become relevant when determining whether administrative judicial remedies are available.

Repeated telephone calls or informal visits may be useful for obtaining information, but they do not necessarily create the same procedural record as a properly documented administrative application.

Can a Foreigner File an Administrative Lawsuit?

Potentially, depending on the procedural circumstances.

Turkish administrative law provides mechanisms for judicial review of administrative acts and, under appropriate conditions, administrative inactivity.

The official citizenship authority itself identifies the Administrative Judicial Procedure Law among the legislation relevant to citizenship administration.

However, an applicant should not file a case merely because the online citizenship status has remained unchanged for several months.

Before litigation, it is necessary to determine:

• Whether there has been a legally relevant administrative application;
• Which authority is responsible;
• Whether the administration has responded;
• Whether administrative silence has acquired legal significance;
• Which type of administrative action is appropriate;
• When the litigation period begins.

These questions are procedural and highly date-sensitive.

What Is an Administrative Silence Case?

Administrative law recognizes situations in which an applicant formally asks an authority to take action but the administration fails to provide the legally relevant response.

Depending on the applicable procedural framework, such silence can eventually allow the applicant to consider judicial review.

For citizenship cases, the precise sequence matters.

A person should not simply calculate time from the original citizenship application and assume that a lawsuit automatically becomes available on a particular anniversary.

The subsequent petitions, administrative responses and notification dates may be equally important.

Can the Applicant Sue the Security Authorities Directly?

Not every delayed citizenship case should be framed as a lawsuit directly against an institution participating in the security investigation.

The first task is to identify the administrative act or inactivity that is legally being challenged and the competent administrative authority responsible for that process.

Citizenship applications are evaluated through the citizenship administration, while other public institutions may provide information necessary for the investigation.

The General Directorate of Population and Citizenship Affairs is responsible for examining and processing citizenship matters through its relevant organizational units.

Therefore, identifying the correct defendant and reviewable administrative conduct requires examination of the particular file.

Can the Court Force the Security Investigation to End?

The precise relief available depends on the type of administrative case and the procedural posture.

An administrative court reviews the legality of administrative action or inaction.

A case concerning an excessively prolonged citizenship process should therefore be distinguished from a demand that the court itself perform the citizenship administration’s investigation.

The legal strategy must focus on the reviewable administrative conduct.

Can the Court Directly Grant Turkish Citizenship?

Applicants should not assume that challenging a delay means the court will simply grant citizenship.

Citizenship acquisition remains subject to the statutory decision-making framework.

For example, official guidance confirms that exceptional citizenship is subject to the applicable proposal and presidential decision process, provided that the applicant has no national-security or public-order obstacle.

Accordingly, litigation over administrative delay primarily concerns the legality of the administrative process rather than replacing the competent authority’s citizenship assessment.

Does Meeting All Citizenship Requirements Create an Automatic Right to Citizenship?

Not necessarily.

Under the general citizenship route, applicants must satisfy several statutory conditions, including residence, integration-related requirements, income or profession and the absence of national-security or public-order obstacles.

Satisfying the preliminary application requirements should therefore not automatically be interpreted as guaranteeing a positive citizenship decision.

This distinction is particularly important in litigation.

An applicant may argue that the administration must lawfully process the application without necessarily arguing that citizenship must automatically be granted.

What If the Applicant Applied Through Investment?

Citizenship by investment also requires distinction between:

Investment eligibility

and

Final citizenship approval.

Obtaining the required investment eligibility documentation does not eliminate the separate citizenship assessment.

Official guidance confirms that exceptional citizenship applications are evaluated and that national-security and public-order considerations remain relevant before the file proceeds through the applicable final decision process.

Therefore, an investor can potentially experience a prolonged security examination even after completing the qualifying investment.

Can an Investor Challenge a Security Investigation That Lasts for Years?

Potentially, depending on the procedural history.

The fact that the qualifying property, deposit, investment or other requirement has already been verified can be relevant to identifying where the delay actually exists.

The applicant should distinguish between:

• Investment verification delay;
• Residence procedure delay;
• Citizenship document review;
• Security investigation;
• Final decision delay.

Legal action should address the actual administrative problem rather than treating all stages as one process.

What About Citizenship Through Marriage?

Citizenship through marriage also involves national-security and public-order considerations.

Official guidance confirms that marriage to a Turkish citizen does not automatically confer citizenship. A qualifying foreign spouse must satisfy additional statutory conditions, including the absence of a national-security or public-order obstacle.

A prolonged security examination can therefore also arise in marriage-based applications.

Can an Old Criminal Investigation Cause the Delay?

Potentially.

If the applicant previously faced a criminal investigation, prosecution or another judicial proceeding, the current legal status of that matter may become important.

The applicant should distinguish between:

• Pending investigation;
• Pending prosecution;
• Final conviction;
• Acquittal;
• Non-prosecution decision;
• Closed proceeding.

An old allegation should not automatically be treated as equivalent to a final conviction.

What If the Applicant Was Acquitted?

The applicant should preserve the final court decision.

Where an old criminal case appears to be affecting citizenship processing, an acquittal may be highly relevant to clarifying the applicant’s current legal position.

The same applies where an investigation ended without prosecution.

The objective is to ensure that any assessment is based on current and accurate information.

Can a Previous Deportation Decision Cause a Long Security Review?

Potentially.

Previous immigration history may require additional examination depending on the reason for the decision.

Relevant matters can include:

• Previous removal decision;
• Entry ban;
• Restriction record;
• Immigration violation;
• Overstay;
• Security-related immigration measure.

The applicant should determine whether the previous measure is still effective and whether it was challenged, cancelled or expired.

What If an Entry Ban Was Removed Years Ago?

The applicant should preserve documentation demonstrating the current status.

A historical administrative measure and a currently effective restriction are not necessarily the same thing.

If outdated information appears to be affecting the citizenship file, obtaining the underlying administrative records and final decisions can become important.

Can Incorrect Identity Information Delay the Security Investigation?

Yes.

Identity discrepancies can create substantial difficulties in citizenship processing.

Problems may involve:

• Different name spellings;
• Different surnames;
• Different dates of birth;
• Different places of birth;
• Passport changes;
• Multiple nationalities;
• Inconsistent parental information.

Official citizenship guidance specifically recognizes the significance of inconsistencies between foreign identity documents and Turkish civil-registration information.

Such discrepancies should be addressed rather than ignored.

What If the Applicant Has the Same Name as Another Person?

Mistaken identity can potentially create serious administrative problems.

If the applicant suspects that records belonging to another person are being associated with their file, strong identity evidence may be required.

Useful documentation can include:

• Current and former passports;
• Birth certificate;
• National identity records;
• Parent information;
• Entry and exit information;
• Other official identity documents.

The appropriate correction procedure depends on where the incorrect record exists.

Can the Applicant Request Information About the Security Investigation?

The applicant may submit a request concerning the status and processing of the citizenship application.

However, this does not mean that every detail of a security investigation must necessarily be disclosed.

Security-related information can be subject to statutory confidentiality and disclosure restrictions.

The official citizenship tracking mechanism itself provides applicants only with the general status of their application.

Therefore, an applicant may know that the citizenship procedure remains under investigation without obtaining access to every internal record.

Can a Lawyer Access Confidential Security Records?

Legal representation does not automatically create unrestricted access to confidential security or intelligence information.

However, a lawyer can assist with:

• Reviewing the known citizenship file;
• Establishing the procedural chronology;
• Identifying identity discrepancies;
• Examining previous criminal proceedings;
• Reviewing immigration decisions;
• Preparing formal administrative petitions;
• Evaluating administrative silence;
• Filing administrative proceedings where appropriate.

Official citizenship guidance also confirms that various post-application procedures may be handled through an appropriately authorized representative.

What If the Administration Says Only “Investigation Continues”?

The applicant should document the response.

If the same generic response continues for an exceptionally long period, the next step may be a more structured formal application requesting completion of the pending procedure.

The legal significance of continued inactivity must then be evaluated according to:

• Dates;
• Previous applications;
• Responses;
• Applicable administrative procedure;
• Citizenship category.

Can the Applicant Claim Compensation for Excessive Delay?

This is more difficult and should not be assumed automatically.

A delay in a citizenship application does not by itself establish a right to monetary compensation.

A compensation claim would require a separate legal basis and examination of matters such as unlawful administrative conduct, actual damage and causation.

The applicant should therefore distinguish between:

Seeking completion or judicial review of the citizenship procedure

and

Seeking monetary damages because of the delay.

They are different legal questions.

Should the Applicant Withdraw and Reapply?

Not automatically.

Withdrawing an application that has already been pending for years may eliminate the practical benefit of the existing procedural history and require the applicant to begin again.

A new application can involve:

• New documents;
• Updated eligibility review;
• New administrative processing;
• Another security examination.

Before withdrawing, the applicant should determine why the existing application is delayed.

Can Filing a Lawsuit Harm the Citizenship Application?

Using a lawful judicial remedy does not itself mean that an applicant has committed wrongdoing.

However, litigation strategy should be carefully planned because citizenship cases can involve discretionary administrative assessments, confidential records and strict procedural rules.

The objective should be to obtain lawful administrative processing and judicial review where appropriate, not to create unnecessary parallel proceedings.

Should the Applicant Maintain Their Residence Permit?

Yes, where a residence permit or another lawful immigration basis remains necessary.

A pending citizenship application should not automatically be treated as permission to remain or work in Turkey.

The applicant should separately maintain the appropriate immigration status while citizenship proceedings continue.

This becomes particularly important where the security investigation lasts several years.

2026 Practical Strategy When a Citizenship Security Investigation Never Ends

A foreign applicant facing prolonged security investigation can approach the problem in five stages.

Stage 1 — Build the Timeline

Record the original citizenship application date and every subsequent procedural development.

Stage 2 — Identify Possible Problems

Review:

• Criminal history;
• Immigration history;
• Entry bans;
• Restriction records;
• Passport changes;
• Identity inconsistencies;
• Marriage or divorce;
• Missing documents.

Stage 3 — Submit a Formal Administrative Request

Where appropriate, formally request information and completion of the citizenship procedure.

Keep proof of submission.

Stage 4 — Evaluate the Administrative Response

Determine whether the authority:

• Responded substantively;
• Requested additional documents;
• Continued the investigation;
• Issued a negative decision;
• Remained silent.

Stage 5 — Evaluate Administrative Judicial Review

Where prolonged administrative inactivity continues, the applicant should determine whether the procedural requirements for an administrative court case have arisen.

The dates of the administrative application, response or legally relevant silence can be critical.

Frequently Asked Questions

1. Can I sue because my Turkish citizenship security investigation has taken years?

Potentially. A prolonged investigation may justify formal administrative steps and, depending on the procedural history, administrative judicial review. The duration alone does not automatically determine whether a lawsuit is available.

2. Is there a fixed maximum duration for citizenship security investigations?

There is no universal publicly stated timetable guaranteeing completion of every citizenship security investigation within a particular number of months.

3. Does a security investigation lasting two years mean my application will be rejected?

No. Processing time alone does not establish the eventual outcome.

4. Should I submit a petition before filing a lawsuit?

A properly documented administrative application can be highly important in determining the availability and timing of judicial remedies.

5. Can a court simply grant me citizenship because the investigation took too long?

A delay case should not be treated as an automatic entitlement to citizenship. The citizenship decision remains subject to the applicable statutory framework.

6. Can an old criminal investigation delay citizenship?

Potentially. The final outcome of the criminal matter can be important. An acquittal or a decision ending an investigation should be properly documented.

7. Can a previous entry ban or deportation decision cause problems?

Potentially, depending on its basis and current legal status. A historical measure should be distinguished from a restriction that remains legally effective.

8. Can investment citizenship applications also face long security investigations?

Yes. Completing the qualifying investment does not eliminate the separate national-security and public-order assessment required within the exceptional citizenship framework.

9. Can a lawyer obtain all confidential security records?

Not automatically. Confidentiality rules may limit access to certain security-related material. Legal representation can nevertheless be used to pursue appropriate administrative and judicial remedies.

10. What should I do if my application status has not changed for years?

Create a complete chronology, review possible legal or documentary problems, submit an appropriate formal administrative request and evaluate administrative judicial remedies if the inactivity continues.

Client-Focused Legal Support for Citizenship Security Investigation Delays

A Turkish citizenship application remaining under security investigation for an exceptionally long period should be examined differently from an ordinary application that is simply taking several months to process.

The legal strategy may depend on the applicant’s previous criminal proceedings, immigration history, entry restrictions, identity records, citizenship category, previous administrative petitions and the length and nature of the inactivity.
