Immigration Detention at Istanbul Airport

Immigration Detention at Istanbul Airport: What Foreigners Need to Know

Foreign nationals arriving at Istanbul Airport may sometimes experience immigration procedures that go beyond ordinary passport control. In some cases, a traveller may be held in a controlled area, refused entry, or become subject to administrative detention under Turkish immigration law.

For a foreign national and their family, the situation can be confusing. They may not know whether the person has simply been stopped for additional checks, formally placed under administrative detention, or is facing deportation proceedings.

Understanding the difference between these procedures is therefore important.

What Is Immigration Detention in Turkey?

Administrative detention is an immigration-related measure that can be applied to certain foreign nationals under the conditions established by Turkish law.

It is different from criminal imprisonment.

A foreign national may encounter administrative detention in connection with procedures concerning removal, deportation or other immigration matters.

If a person is formally placed under administrative detention, the authorities should follow the applicable legal procedure and issue the relevant administrative decision.

Can a Foreigner Be Detained at Istanbul Airport?

A foreign national experiencing an immigration problem at Istanbul Airport may be held while the relevant authorities assess the situation.

However, being held at the airport does not automatically mean that formal administrative detention has been imposed.

There can be an important distinction between:

  • Additional passport checks;
  • Temporary holding during border procedures;
  • Refusal of entry;
  • Administrative detention;
  • Deportation proceedings; and
  • Criminal detention.

The foreign national should therefore determine what legal status applies to their particular situation.

Why Might a Foreigner Be Subject to Administrative Detention?

Administrative detention can arise in connection with immigration and removal procedures.

Possible circumstances may include:

  • A deportation procedure;
  • An inability to establish the person's identity or nationality;
  • A risk that the person may abscond;
  • A violation of immigration rules;
  • An existing removal-related decision; or
  • Other circumstances recognised under Turkish immigration legislation.

The actual legal basis must be assessed according to the individual case.

Is Administrative Detention the Same as Deportation?

No.

Administrative detention concerns the temporary restriction of a foreign national's freedom in connection with an immigration procedure.

Deportation, or removal from Turkey, concerns the process of requiring a foreign national to leave the country under the applicable immigration rules.

The two procedures can be connected, but they are legally distinct.

A foreign national may therefore need to address both the detention decision and the underlying removal or deportation procedure.

What Happens After Administrative Detention?

Depending on the circumstances, a foreign national subject to administrative detention may be transferred to a removal centre.

The person may remain there while the relevant immigration procedure is carried out.

The foreign national or their relatives may need to determine:

  • Where the person is being held;
  • Why administrative detention was imposed;
  • Whether a deportation decision exists;
  • Whether an entry ban may be imposed;
  • What legal remedies are available; and
  • Whether legal representation can be arranged.

Can a Lawyer Challenge Administrative Detention?

Depending on the circumstances, a foreign national may have legal remedies concerning an administrative detention decision.

An immigration lawyer can examine:

  • The administrative detention decision;
  • The reasons given by the authorities;
  • The foreigner's immigration history;
  • Any deportation decision;
  • Available supporting documents; and
  • Applicable procedural requirements.

The lawyer can then assess whether a legal application or challenge may be available.

The precise procedure depends on the facts of the case and the relevant administrative decisions.

What Rights Does a Foreign National Have?

Foreign nationals subject to immigration procedures have rights under Turkish law.

Depending on the procedure, these may include rights concerning:

  • Notification of relevant administrative decisions;
  • Access to legal assistance;
  • Communication with representatives or family members where applicable;
  • Interpretation or translation where necessary;
  • Challenging certain administrative decisions; and
  • Judicial review where legally available.

The scope and exercise of these rights depend on the person's specific legal status.

What If You Do Not Understand Turkish?

Language can become a significant issue during immigration procedures.

A foreign national who does not speak Turkish may have difficulty understanding:

  • Why they are being held;
  • What documents they are being asked to sign;
  • Whether they are subject to administrative detention;
  • Whether a deportation decision has been issued; or
  • What legal remedies may be available.

If you do not understand a document, you should request an explanation or appropriate interpretation before signing whenever possible.

What If Your Family Member Is Detained at Istanbul Airport?

When a family member is stopped at Istanbul Airport, relatives may have difficulty finding out what is happening.

They may not know whether the person:

  • Has been refused entry;
  • Is being held temporarily;
  • Has been placed under administrative detention;
  • Has been transferred to a removal centre;
  • Is facing deportation; or
  • Has an entry ban or Tahdit code.

An immigration lawyer can help the family understand the relevant legal procedure and determine what information and documents are needed.

Can a Lawyer Visit or Represent a Detained Foreigner?

Depending on the applicable procedure and circumstances, an immigration lawyer may assist a detained foreign national with legal representation.

The lawyer may examine the relevant administrative decisions, communicate regarding the legal matter and pursue available legal remedies where appropriate.

The precise arrangements for communication, representation and access depend on the location and legal status of the foreign national.

What Is a Removal Centre?

A removal centre is a facility used in Turkey for certain foreign nationals subject to removal-related procedures.

A person initially stopped at Istanbul Airport may, depending on the circumstances, subsequently be transferred to a removal centre.

Once a foreign national has been transferred, family members may need to determine the location of the person and obtain information about the relevant administrative procedure.

What Is the Difference Between a Removal Centre and a Prison?

A removal centre is part of the immigration-administration system and is different from a criminal prison.

A foreign national may be held in a removal centre because of an immigration procedure rather than because they have been convicted of a criminal offence.

This distinction is important when assessing the person's legal position.

Can Administrative Detention Affect Future Entry to Turkey?

The consequences for future entry depend on the circumstances.

An immigration case may involve additional measures such as:

  • An entry ban;
  • A Tahdit code;
  • A deportation decision; or
  • Other immigration restrictions.

Therefore, after an administrative detention or removal procedure, it can be important to determine whether any restriction has been recorded against the foreign national before attempting to travel to Turkey again.

What Should You Do If You Are Detained at Istanbul Airport?

If you or a family member is experiencing an immigration detention problem, consider the following steps.

Request Information About the Decision

Try to establish the reason for the detention and whether a written administrative decision has been issued.
