Refused Entry to Turkey at Istanbul Airport

Refused Entry to Turkey at Istanbul Airport: Reasons, Procedures and Legal Assistance

Being refused entry to Turkey at Istanbul Airport can be stressful, particularly for foreign nationals who have already obtained a visa or made travel arrangements.

A foreign national may arrive at Istanbul Airport expecting to enter Turkey but instead be directed to additional immigration checks or informed that they cannot enter the country.

The reason may relate to a visa, passport, previous immigration history, entry restriction, Tahdit code or another legal issue.

Understanding the distinction between refusal of entry, deportation and administrative detention is important when dealing with an airport immigration problem.

What Does Refused Entry to Turkey Mean?

A refusal of entry means that a foreign national attempting to enter Turkey is not admitted through the border.

The decision can arise for different legal reasons depending on the person's circumstances.

Being refused entry does not necessarily mean that the person has committed a criminal offence or that a deportation decision has been issued.

The exact reason should be established from the relevant documents and information provided by the authorities.

Why Can You Be Refused Entry to Turkey?

There can be various reasons why a foreign national may experience a problem at the Turkish border.

Potential issues may include:

  • Invalid or unsuitable travel documents;
  • Visa problems;
  • Passport validity;
  • Previous overstay;
  • Previous deportation;
  • Active entry ban;
  • Tahdit code;
  • Inconsistencies concerning the purpose of travel;
  • Failure to satisfy applicable entry conditions; or
  • Other grounds provided under Turkish law.

The reason applicable to one traveller may not apply to another.

Can You Be Refused Entry Even With a Valid Turkish Visa?

A visa does not necessarily guarantee admission to Turkey.

A foreign national may have a valid visa but still encounter a border-control problem because another immigration restriction or requirement applies.

For example, a previous immigration record may be relevant even if the traveller has obtained a new visa.

This is why foreign nationals with previous immigration problems should consider checking their status before travelling.

What Happens at Istanbul Airport When Entry Is Refused?

The traveller may be directed to an area for additional immigration procedures.

Authorities may review:

  • Passport;
  • Visa;
  • Previous Turkish immigration history;
  • Entry restrictions;
  • Tahdit codes;
  • Travel arrangements; and
  • Other relevant information.

The traveller should try to establish exactly what decision has been made and why.

Is Refusal of Entry the Same as Deportation?

No.

These are different immigration procedures.

Refusal of entry concerns a foreign national attempting to enter Turkey.

Deportation generally concerns the removal of a foreign national from Turkey following a formal deportation decision.

A traveller refused entry at Istanbul Airport should therefore not automatically assume that they have received a deportation decision.

Is Refusal of Entry the Same as Administrative Detention?

No.

A foreign national may be required to remain in a controlled area while an immigration procedure is conducted.

This does not automatically mean that the person has been formally placed under administrative detention.

If the authorities issue a formal administrative detention decision, that decision should be reviewed separately.

What If You Are Held in the Airport Transit Area?

Some travellers may remain in a controlled airport area while their immigration situation is being determined.

If you cannot freely leave the area, ask:

  • Why you are being held;
  • Whether a formal decision has been issued;
  • Whether you are being refused entry;
  • Whether you are under administrative detention; and
  • Whether you can obtain legal assistance.

If you do not understand Turkish sufficiently, communicate this clearly.

What If Your Visa Is Correct but Entry Is Still Refused?

A valid visa is only one part of the immigration assessment.

If entry is refused despite a valid visa, there may be another reason for the decision.

Possible issues can include:

  • Previous immigration violations;
  • Entry ban;
  • Tahdit code;
  • Previous deportation;
  • Inconsistent information;
  • Passport-related issues; or
  • Other legal grounds.

The foreign national should request clarification and preserve the relevant documentation.

Can a Previous Overstay Cause Refusal of Entry?

A previous overstay may affect a person's future immigration status depending on the circumstances.

The authorities may consider the person's previous immigration history when the person attempts to enter Turkey again.

If an entry restriction was imposed following the overstay, the foreign national may be refused entry while the restriction remains active.

Can a Previous Deportation Cause Refusal of Entry?

Yes, a previous deportation may be relevant to a subsequent attempt to enter Turkey.

The foreign national may have an associated:

  • Entry ban;
  • Tahdit code; or
  • Other immigration restriction.

Before travelling to Turkey after a previous deportation, it can be important to investigate whether the restriction remains active.

What Is a Tahdit Code?

A Tahdit code generally refers to a restriction recorded in Turkish immigration systems.

A traveller may discover a Tahdit-related issue only when attempting to enter Turkey.

The particular code should be identified because the legal consequences can differ depending on the type of restriction.

Can a Turkey Entry Ban Cause Refusal of Entry?

Yes.

If an active entry ban applies to a foreign national, the person may be refused entry at the Turkish border.

The traveller should determine:

  • Why the entry ban exists;
  • When it started;
  • How long it applies;
  • Whether it remains active; and
  • Whether there is a legal procedure for addressing it.

What Should You Do If You Are Refused Entry at Istanbul Airport?

If you are refused entry, try to follow these steps.

1. Ask for the Reason

Determine the legal or administrative reason for the refusal.

2. Request Documentation

Ask for copies of relevant decisions or written information where possible.

3. Check Your Immigration History

Consider whether you previously:

  • Overstayed;
  • Had a residence permit cancelled;
  • Were deported;
  • Received an entry restriction; or
  • Had another immigration problem.

4. Seek Legal Assistance

If the matter involves an entry ban, Tahdit code, deportation or administrative detention, an immigration lawyer can review the situation.

Can You Appeal a Refusal of Entry?

The available legal remedy depends on the nature of the decision and the circumstances.

A refusal of entry should therefore be examined together with any written decision and the relevant immigration records.

A lawyer can determine whether an administrative application, judicial procedure or another legal remedy may be available.

What If You Have a Turkish Spouse?

A Turkish spouse can be a relevant circumstance in an immigration case.

However, marriage does not automatically guarantee admission to Turkey or cancel an existing entry restriction.

If your spouse is a Turkish citizen, documents concerning the marriage and family circumstances should be kept available for legal assessment.

What If Your Children Live in Turkey?

Children living in Turkey may also be relevant to the circumstances of an immigration case.

Useful documents can include:

  • Birth certificates;
  • Evidence of nationality;
  • Custody documents where relevant;
  • Family records; and
  • Evidence concerning residence in Turkey.

Family circumstances do not automatically eliminate an entry restriction, but they may be relevant to an available legal procedure.

What If You Have a Residence Permit?

A residence permit may be relevant when determining the foreign national's immigration history.

However, a previous residence permit does not automatically guarantee admission if another immigration restriction applies.

If your residence permit has expired, been cancelled or been rejected, the relevant documents should be reviewed.

What If You Were Travelling for Tourism?

Tourists should be prepared to explain the purpose of their visit if questioned.

Documents that may be useful include:

  • Hotel reservation;
  • Return ticket;
  • Travel itinerary;
  • Travel insurance where applicable; and
  • Other supporting travel documents.

Providing accurate and consistent information is important during border procedures.

What If You Were Travelling for Business?

Business travellers may be asked to explain the purpose of their visit.

If appropriate, supporting documents may include:

  • Invitation letter;
  • Company information;
  • Meeting details;
  • Conference registration; or
  • Other relevant business documentation.

The traveller should ensure that the planned activities correspond to the applicable immigration status.

What If You Do Not Speak Turkish?

Language difficulties can make an airport immigration procedure more complicated.

If you do not sufficiently understand Turkish, inform the authorities.

Before signing an important document concerning refusal of entry, detention or deportation, make sure you understand its contents and legal significance.

What Documents Should You Keep?

If you have an immigration problem at Istanbul Airport, preserve copies of:

  • Passport;
  • Visa;
  • Flight ticket;
  • Boarding pass;
  • Previous Turkish visas;
  • Residence permit;
  • Deportation documents;
  • Entry-ban documents;
  • Tahdit-related documents;
  • Overstay records; and
  • Other correspondence with Turkish authorities.

These documents can help a lawyer reconstruct the immigration history.

Can You Enter Turkey Through Another Airport?

If an active immigration restriction applies nationally, travelling through another Turkish airport does not necessarily resolve the problem.

The relevant immigration status should be established before attempting another entry.

Changing the airport should not be treated as a substitute for resolving an underlying immigration restriction.

Can You Apply for a New Visa After Being Refused Entry?

A new visa does not necessarily resolve the reason for a previous refusal of entry.

If the refusal was connected with an entry ban, Tahdit code or previous immigration decision, the underlying issue may need to be addressed first.

The foreign national should therefore determine why entry was refused before simply submitting another visa application.
