Deportation, Entry Bans, and Restriction Codes in Turkey: A 2026 Guide for Foreign Nationals

1. Three Things That Get Confused

This guide explains the three measures, how they differ, and what can realistically be done about each in 2026. As a practice combining a licensed Istanbul attorney with a certified sworn English–Turkish translator, we work from the original Turkish decision and the file record — because the precise ground and code determine everything that follows, and a misread can cost the case.

People use these terms interchangeably; the law does not.

• Deportation (sınır dışı etme) — a decision to remove a foreigner who is currently in Turkey.
• Entry ban (Türkiye'ye giriş yasağı) — a decision barring a foreigner from entering Turkey, usually for a fixed period.
• Restriction code (tahdit kodu) — an administrative code recorded on a person's file that, in practice, appears in the migration system as an entry ban and signals why it was imposed.

They often travel together — a deportation is typically followed by an entry ban, expressed through a restriction code — but each has its own legal basis and its own route of challenge.

2. Deportation (sınır dışı etme)

A deportation decision is an administrative act, taken by the governorate or on the instruction of the Presidency of Migration Management, under the Law on Foreigners and International Protection No. 6458. The grounds are listed in Article 54 — they include, among others, those to be removed after serving a sentence under Article 59 of the Turkish Penal Code, members or supporters of a terrorist or criminal organisation, those who used false information or documents in entry/visa/residence procedures, those who pose a threat to public order, security, or health, and those who overstayed a visa or visa exemption by more than ten days. The fines and entry-ban tiers that follow an overstay are set out in our detailed guide to visa overstay fines and entry-ban tiers.

Critically, Article 55 lists those who cannot be deported — for example, where there are serious indications a person would face the death penalty, torture, or inhuman or degrading treatment in the destination country (the principle of non-refoulement).

Where removal is decided, Article 56 generally allows a departure period of between 15 and 30 days — but that period is not granted to those who pose a flight risk, used false documents, breached entry/exit rules, or are deemed a threat to public order, security, or health.

3. Administrative Detention (idari gözetim)

In parallel with deportation, a foreigner may be placed in administrative detention under Article 57 of Law No. 6458, where there is a flight risk, a breach of entry/exit rules, use of false documents, failure to leave within the granted period, or a threat to public order, security, or health. The governorate must decide within 48 hours; detention is served in a removal centre and may not exceed six months, extendable up to twelve months in defined circumstances. A detention decision can be challenged before the Magistrate's Court (sulh ceza hâkimliği) within seven days.

4. Entry Bans (Türkiye'ye giriş yasağı)

An entry ban is governed by Article 9 of Law No. 6458. The Presidency of Migration Management may bar entry to foreigners considered objectionable on grounds of public order, security, or health, and a foreigner who has been deported is barred by the Directorate or the governorate. The ban is for a maximum of five years; where there is a serious threat to public order or security, it may be extended by up to a further ten years. Separately, Article 7 lists the categories of foreigners who are not admitted to Turkey at all (the "inadmissible passenger" categories).

5. Restriction Codes (tahdit kodları)

This is the part most people search for, and the part where care matters most. Restriction codes are administrative codes, not a list set out article-by-article in the statute. They are recorded in the migration system, where they appear as an entry ban, and each signals the reason behind the restriction. They are applied within the framework of Law No. 6458, not invented arbitrarily — but their exact meaning, duration, and removal route are case-specific.

Broadly, the codes fall into families:

• V-codes tend to concern residence-related issues — for example, V-69 (residence permit cancelled), V-70 (sham marriage), V-71 (not found at the registered address).
• G-codes tend to concern security or health — for example, G-78 (carrier of a communicable disease), G-87 (assessed as a general-security risk, including suspected links to terrorism).
• Ç-codes tend to concern entry/exit and judicial matters — for example, Ç-113 (illegal entry or exit), with related codes covering visa/residence overstays graduated by length.

A G-87 in particular can be severe: it can lead to a refused entry or a deportation, and because it often rests on an assessment rather than a final conviction, it raises real questions of proportionality — especially where a person has a Turkish spouse and children. The European Convention on Human Rights' protection of family life (Article 8) is frequently central to challenging such a code where the security ground is not supported by concrete, lawful evidence. Nationals from countries that face structural scrutiny at the entry-control level — including those we assist through our Iranian nationals residence permit practice — encounter this dynamic with particular regularity.

6. The Deadlines — Read This Twice

This is where cases are won or lost.

• A deportation decision can be challenged within seven days of notification, by application to the governorate or directly by an annulment action before the Administrative Court, under Article 53 of Law No. 6458. As a rule, where an annulment action is brought, the person is not removed until the proceedings conclude.
• An administrative detention decision — seven days to the Magistrate's Court.
• An entry ban or restriction code is challenged as an administrative act through an annulment action before the Administrative Court, within the general 60-day time limit under the Administrative Procedure Law No. 2577.

Miss the seven-day window on a removal, and the practical position becomes far harder. Speed is not optional here.

7. How a Ban or Code is Challenged or Lifted

There is usually more than one route. The principal one is an annulment action before the Administrative Court, arguing that the measure lacks a concrete, lawful basis or is disproportionate; an interim stay of execution, if granted, can allow entry while the case proceeds. An administrative application to have the code removed may also be available. And in defined situations — for instance a pressing family or humanitarian reason — an annotated visa (meşruhatlı vize) issued with special permission can allow entry despite an existing ban. Court timelines vary, but these cases commonly take several months to resolve. Where the person facing the ban has a spouse or children in Turkey, a distinct constitutional defence applies — we analyse the family-life defence separately.

What none of this rewards is delay or guesswork. The code on the file has a specific meaning; the challenge has to be built against that specific meaning.

8. What Actually Helps

Three things, again. The deadline — measured in days for removals and detention. The exact ground and code — stated in Turkish, and frequently misunderstood by the person affected. And the evidentiary file — the documents and the petition that show, concretely, that the measure is unlawful or disproportionate.

This is where the firm's dual capability is decisive. We read the decision and the code in the original Turkish, translate the supporting evidence to sworn-translation standard, and frame the challenge so the legal argument and the certified proof work as one. For permit or citizenship refusals that are not removals, see our separate guide on appealing a refused Turkish visa, residence permit, or citizenship decision.

9. How SP Law Istanbul Helps

We act urgently — because in these matters the clock is usually already running. We assess the decision and the code, advise honestly on the prospects, and handle the annulment action, the detention challenge, or the application to lift a code, including arguments on proportionality and family life where they apply. Where an annotated visa or administrative route is the better path, we pursue that instead.
