Can a pending criminal investigation or court case affect Turkish citizenship? Learn whether a conviction is required, how pending proceedings affect general, marriage-based and investment citizenship, and what applicants can do in Turkey in 2026.

Yes. An ongoing criminal case can significantly affect a Turkish citizenship application even before there is a final conviction. Depending on the citizenship route, the nature of the allegations and the procedural stage of the criminal case, the application may not be accepted for processing, may remain pending while authorities conduct further examination, or may eventually be rejected if the circumstances are considered incompatible with the applicable citizenship requirements.

However, an ongoing criminal case is not the same as a final criminal conviction, and it should not automatically be assumed that every investigation or prosecution permanently prevents a foreigner from obtaining Turkish citizenship.

For general naturalization, Article 11 of Turkish Citizenship Law No. 5901 requires, among other conditions, good moral character and the absence of a condition constituting an obstacle concerning national security and public order. The law also expressly states that satisfying the statutory requirements does not give the foreigner an absolute right to acquire citizenship.

For foreign applicants in Ankara, Istanbul, Izmir, Mersin, Bursa and throughout Turkey, a pending criminal case should therefore be examined together with the citizenship file rather than treated as an entirely separate matter.

Can a Pending Criminal Case Stop a Citizenship Application?

Yes, particularly at the application stage.

Official citizenship guidance concerning general naturalization states that during preliminary examination, an application is not accepted where the foreign applicant is being tried for an offence, has been convicted, or is detained, among other specified circumstances.

This is an important distinction.

The applicant does not necessarily need to have received a final conviction before the criminal proceedings create a citizenship problem.

If criminal proceedings are already pending when the foreigner attempts to submit a general citizenship application, the pending proceedings may prevent the application from being accepted under the administrative preliminary-examination rules.

Does This Mean Every Criminal Investigation Automatically Prevents Citizenship?

Not necessarily.

The precise stage of the criminal process matters.

A criminal complaint, preliminary investigation, formal prosecution, trial, conviction and final conviction are legally different situations.

The official administrative guidance expressly refers to a person who is being tried, convicted or detained.

Therefore, an applicant should not automatically assume that merely being named in a complaint has exactly the same citizenship consequences as being formally prosecuted before a criminal court.

The actual procedural status should be verified from the criminal file.

What If the Criminal Case Starts After the Citizenship Application?

This can also affect the application.

Suppose a foreigner submits a citizenship application when no criminal proceedings are pending. Several months later, a criminal investigation begins and eventually results in prosecution.

The citizenship application does not necessarily continue as though nothing happened.

Citizenship authorities evaluate applicants throughout the administrative process, particularly regarding good character, national security and public order. Current official guidance confirms that citizenship applications are evaluated by the competent citizenship authority and that national-security and public-order considerations remain part of the decision-making process.

A later criminal case can therefore become relevant before a final citizenship decision is issued.

Does an Ongoing Criminal Case Automatically Mean Citizenship Will Be Rejected?

No.

A pending criminal case and a final citizenship rejection should not be treated as identical.

The citizenship authority may need to consider the nature and status of the proceedings. If the criminal case later ends favorably for the applicant, that outcome can materially change the citizenship assessment.

The presumption of innocence also means that prosecution should not simply be described as equivalent to a final finding of guilt.

Nevertheless, citizenship law contains administrative requirements extending beyond criminal conviction alone. For general naturalization, the applicant must demonstrate good character and must not constitute an obstacle concerning national security or public order.

Which Criminal Cases Create the Greatest Citizenship Risk?

The seriousness and nature of the alleged conduct can make a major difference.

Allegations involving serious violence, organized crime, terrorism-related conduct, fraud, document forgery, trafficking, serious financial crime, narcotics offences or other conduct potentially affecting public order or national security are likely to create greater difficulties than relatively minor allegations.

Official citizenship guidance concerning good character has specifically referred to offences such as theft, smuggling, forgery and fraud as relevant examples.

Each case must nevertheless be evaluated individually.

What If the Criminal Case Ends in Acquittal?

A final acquittal can become extremely important evidence for the citizenship file.

If the citizenship application was delayed or adversely affected because of the criminal prosecution, the applicant should obtain the complete reasoned acquittal judgment and submit it to the citizenship authority.

The applicant should not assume that the citizenship file will automatically be updated immediately after the criminal judgment.

A formal submission may be necessary to demonstrate that the criminal proceedings have ended favorably.

The reasoning of the acquittal can also matter. A judgment establishing that the alleged conduct was not committed may carry different evidentiary significance from a procedural outcome based on another reason.

What If the Investigation Ends Without Prosecution?

This can also substantially improve the applicant’s position.

Where an investigation ends without prosecution, the applicant should obtain the final decision and consider submitting it formally to the citizenship authority.

This is particularly important where the citizenship application has remained pending because of the investigation.

The citizenship authority can then evaluate the application in light of the updated criminal record rather than an unresolved allegation.

What If the Applicant Is Convicted While Citizenship Is Pending?

A conviction can create a considerably more serious problem.

For general naturalization, the authorities may examine whether the conviction is inconsistent with the good-character requirement or constitutes a national-security or public-order obstacle.

The effect will depend on factors including the offence, sentence, whether the judgment is final and the applicant’s overall circumstances.

A minor offence should not automatically be treated as equivalent to serious organized or violent criminal conduct.

Does a Suspended Sentence Matter?

Potentially, yes.

The fact that imprisonment is suspended or another favorable sentencing mechanism applies does not necessarily make the underlying criminal conduct irrelevant to citizenship.

Official administrative citizenship guidance has historically treated certain criminal conduct as relevant to good character even where the punishment was suspended or deferred.

Applicants should therefore obtain the complete judgment and determine its exact legal effect rather than relying solely on whether they physically served a prison sentence.

Can a Pending Criminal Case Affect Five-Year Citizenship?

Yes.

A foreigner seeking citizenship under general naturalization must satisfy all Article 11 requirements. Five years of qualifying residence is only one condition. The applicant must also demonstrate good character and have no national-security or public-order obstacle.

Therefore:

five years of lawful residence does not override a pending serious criminal case.

An applicant may satisfy the residence requirement but still encounter a procedural or substantive citizenship obstacle because of criminal proceedings.

Can a Criminal Case Affect Citizenship Through Marriage?

Yes.

Marriage to a Turkish citizen does not automatically grant citizenship.

Article 16 requires at least three years of continuing marriage and additional conditions, including family unity, absence of conduct incompatible with the marriage, and absence of a national-security or public-order obstacle.

Official administrative guidance concerning marriage-based citizenship also states that an application is not accepted at preliminary examination where the foreign spouse is being tried, convicted or detained.

A pending criminal case can therefore affect marriage-based citizenship even though the marriage itself is genuine.

Can an Ongoing Criminal Case Affect Investment Citizenship?

Yes.

Investment citizenship operates within the exceptional citizenship framework.

Article 12 allows qualifying foreigners to acquire citizenship exceptionally, but the absence of a national-security or public-order obstacle remains an express condition.

Consequently, completing the required investment does not guarantee approval if serious criminal proceedings raise public-order or security concerns.

The financial eligibility and the security assessment are separate components of the citizenship process.

Should an Investor Wait Until the Criminal Case Ends?

That depends on the circumstances.

Where substantial investment is being made primarily for citizenship purposes and the investor already faces serious criminal proceedings, it may be prudent to evaluate the criminal and citizenship risks before committing additional funds.

Citizenship eligibility should never be presented as guaranteed merely because the required investment has been completed.

What If the Criminal Case Is Based on a False Complaint?

The applicant should actively preserve evidence demonstrating that fact.

Foreigners can become defendants following commercial disputes, family disputes, employment conflicts or allegedly fraudulent complaints.

A pending prosecution cannot simply be ignored because the applicant believes the accusation is false.

The criminal case must be defended on its merits, while the citizenship file should be managed separately.

If the proceedings later end favorably, the final decision should be submitted to the citizenship authority.

Can a Criminal Case Abroad Affect a Pending Application?

Potentially, yes.

The citizenship assessment is not necessarily limited to criminal proceedings in Turkey.

Foreign criminal proceedings or records may become relevant to good character, national security or public order depending on the circumstances.

Current official citizenship information also demonstrates that foreign criminal-record documentation may be required in citizenship procedures.

The applicant should accurately establish whether the foreign matter is merely an investigation, a pending prosecution or a final conviction.

Can the Citizenship Authority Wait for the Criminal Case to Finish?

In practice, unresolved criminal proceedings can delay citizenship processing because the final outcome may materially affect the administrative assessment.

The citizenship authority must determine whether the applicant satisfies the applicable statutory requirements before a final citizenship decision is made.

Where the criminal proceedings directly concern good character, public order or national security, their final outcome may therefore become particularly important.

However, prolonged inactivity should be evaluated separately if a citizenship application remains unresolved for an excessive period even after the criminal proceedings have ended.

What Should the Applicant Do When the Criminal Case Ends?

The applicant should obtain the final criminal decision promptly.

Depending on the result, this might include an acquittal judgment, a final decision ending the investigation without prosecution, an appellate judgment overturning a conviction or another final procedural decision.

The applicant should then consider formally submitting the document to the citizenship authority together with a request that the citizenship application be evaluated or resumed in light of the new development.

Can Citizenship Be Rejected Even After an Acquittal?

Potentially, depending on the circumstances, because criminal liability and administrative citizenship assessment are not identical.

However, an acquittal can substantially weaken an adverse assessment where the citizenship concern is based entirely on the same allegations.

If citizenship is subsequently rejected on public-order or security grounds despite a favorable criminal judgment, the applicant should determine exactly what factual basis remains for the administrative decision.

Can the Citizenship Rejection Be Challenged?

Yes, depending on the procedural circumstances.

A final citizenship rejection is an administrative decision that may be subjected to administrative judicial review.

The applicant may need to demonstrate that the administration relied on incorrect information, failed to consider a favorable criminal judgment, treated an allegation as established fact, confused the applicant with another person or otherwise acted unlawfully.

The purpose of the lawsuit is to challenge the legality of the administrative refusal.

Does Winning the Citizenship Case Mean the Court Directly Grants Citizenship?

No.

Turkish Citizenship Law expressly provides that satisfying the statutory conditions does not create an absolute right to acquire citizenship.

An administrative court can review and potentially annul an unlawful refusal. The administration must then act consistently with the judgment.

This should not be confused with the court itself automatically granting Turkish citizenship.

Does a Criminal Case Automatically Cancel a Residence Permit?

No.

Citizenship, criminal proceedings and immigration status are separate legal matters.

An ongoing criminal case does not automatically mean that every residence or work authorization disappears.

However, serious allegations can sometimes result in separate immigration measures where the statutory conditions for those measures are met.

Any residence cancellation, entry restriction or removal decision must therefore be analyzed independently.

Does a Criminal Case Automatically Lead to Removal from Turkey?

No.

Being investigated or prosecuted does not itself constitute an automatic removal order.

If immigration authorities issue a separate removal decision based on the circumstances of the criminal case, that decision is governed by the immigration-law framework and must be challenged separately within the applicable deadline.

The foreigner should never assume that a citizenship problem and a removal case are the same administrative proceeding.

Practical Example: Criminal Case Begins After Application

A foreign professional in Ankara applies for citizenship after completing five years of qualifying residence. Six months later, criminal proceedings begin following a commercial dispute.

The citizenship authority may consider the new proceedings during the application. The applicant should defend the criminal case and ensure that any favorable final decision is subsequently submitted to the citizenship file.

Practical Example: Acquittal During Citizenship Proceedings

A foreign business owner in Istanbul is prosecuted for alleged fraud while a citizenship application is pending. The criminal court later acquits the applicant.

The complete reasoned acquittal judgment should be formally presented to the citizenship authority. If the application is nevertheless rejected on the basis of the same allegations, the relationship between the acquittal and the administrative refusal should be carefully examined.

Practical Example: Marriage-Based Application

A foreign spouse living in Izmir has been married to a Turkish citizen for more than three years but is currently being prosecuted.

Official administrative guidance identifies being tried for an offence as an obstacle at the preliminary application stage for marriage-based citizenship.

The applicant should therefore determine whether waiting for the criminal proceedings to conclude is necessary before a viable citizenship application can proceed.

Practical Example: Investment Applicant

A foreign investor in Bursa completes the financial requirements for exceptional citizenship but becomes involved in a serious criminal prosecution before the citizenship decision is issued.

Investment compliance does not eliminate public-order and national-security screening.

The investor should therefore address the criminal proceedings rather than assuming the investment automatically guarantees citizenship.

Practical Example: Investigation Ends Favorably

A foreign applicant in Mersin has a citizenship application that remains pending while a criminal investigation continues. The investigation eventually ends without prosecution.

The applicant should obtain the final decision and formally request that the citizenship file be evaluated in light of the favorable outcome.

Legal Assistance for Criminal Cases Affecting Turkish Citizenship Applications

An ongoing criminal case can have a substantial effect on Turkish citizenship, but applicants should avoid two opposite mistakes: assuming that a pending accusation is irrelevant until conviction, or assuming that being prosecuted permanently eliminates every possibility of citizenship.

Official citizenship guidance shows that pending prosecution can already create a procedural obstacle at the preliminary application stage. At the same time, Turkish Citizenship Law requires broader assessment of good character, national security and public order, and distinguishes those administrative considerations from a final criminal conviction.

The correct strategy depends on the stage of both proceedings. The applicant may need to coordinate the criminal defence with the citizenship application, preserve favorable criminal decisions, submit an acquittal or decision ending the investigation, request renewed evaluation of a delayed citizenship file or challenge an eventual citizenship refusal before the administrative courts.

Firat Fesih Kaya Law Office provides legal assistance to foreign professionals, investors, entrepreneurs, spouses of Turkish citizens and long-term residents in Ankara, Istanbul, Izmir, Mersin, Bursa and throughout Turkey whose citizenship applications are affected by criminal investigations, prosecutions, criminal judgments, public-order assessments or national-security concerns.

Legal assistance may include reviewing the criminal and citizenship files together, evaluating whether an application can currently proceed, submitting favorable criminal decisions to the citizenship authorities, challenging citizenship refusals based on outdated or incorrect criminal information and coordinating separate immigration proceedings where necessary.

The key 2026 principle is clear: an ongoing criminal case can affect a Turkish citizenship application even without a final conviction. However, prosecution is not the same as guilt, and a later acquittal or favorable termination of the criminal proceedings can materially change the citizenship assessment. Applicants should manage the criminal and citizenship proceedings together and promptly place the final criminal outcome before the citizenship authorities.
