You land at Istanbul or Antalya, hand over your passport, and are directed to a side room. An officer tells you that you will not be admitted and that you will be returned on the next available flight. This is the INAD procedure — "inadmissible passenger" — and it happens to people with valid visas, confirmed hotels and no idea why. This article explains what is happening, what can be done in the hours available, and what to do afterwards.
What INAD means
INAD is airline and border terminology for a passenger who is refused admission to a country at the border. The person has not entered legally; they are held in the transit area pending return, and the carrier that brought them is responsible for taking them back.
In Türkiye, entry is refused under the border provisions of Law No. 6458 and the applicable regulations. Grounds include: an entry ban or restriction code; documents that are invalid, expired or assessed as false; inability to justify the purpose of the visit or to show sufficient means; the ninety-day limit within a hundred and eighty days already exhausted; public order, security or health grounds; or an assessment that the stated purpose is not the real one.
Why it happens to people with valid visas
A visa is permission to travel to the border, not a guarantee of entry. Officers assess admissibility at the border itself.
The situations that recur:
- An entry ban the traveller did not know about, from an old overstay or a previous refusal.
- Miscounting the ninety days. The allowance is ninety days within a rolling hundred and eighty, and border runs do not reset it.
- A pattern of visits suggesting residence rather than tourism.
- Inability to explain the trip — no accommodation booked, no return ticket, no means.
- Document problems: insufficient passport validity, a visa that does not match the purpose.
- Mistaken identity, where a name resembles one in a database.
What happens in the transit area
The person is held in a designated area, not admitted to the country. The airline is notified and arranges return, usually on the next available service to the point of departure. Waiting periods vary from hours to, occasionally, more than a day.
What the person is entitled to: to know that entry has been refused, to contact their consulate, and to legal assistance. In practice, exercising these depends on being able to communicate — which is why the first call should be to a lawyer or a family member who can instruct one.
What the person should not do: sign documents they do not understand, become confrontational with officers, or attempt to leave the transit area. Each makes the position materially worse and can convert an administrative refusal into something recorded far more seriously.
What can be done in the time available
Honestly: not much, and less the longer it is left. The realistic possibilities are:
- Correcting a factual error immediately. Where the refusal rests on a document the traveller has, or on a mistaken identity that can be evidenced, presenting it at once is the only intervention likely to work in real time.
- Consular contact, which can help with communication and welfare though not with the admissibility decision.
- A lawyer contacting the border authority. Where the refusal appears to rest on a code or an assessment that can be clarified, an immediate approach is occasionally productive. This depends entirely on being instructed within the hours available.
Litigation cannot be conducted in the time before a flight leaves. The value of a lawyer at this stage is speed of communication and knowing what to ask, not obtaining a court order.
The refusal is recorded
This is the part travellers underestimate. A refused entry is entered on the record and is visible in every subsequent application — for a visa, for a residence permit, for a work permit, in a citizenship security screening.
Where a restriction code was the cause, the refusal confirms and compounds it. Where there was no code before, the refusal itself may generate one.
For that reason, the useful work happens after the return flight rather than in the transit area.
After you are returned
- Establish what is recorded. An enquiry with the migration authorities, which a lawyer can make under a power of attorney without you travelling. This is the indispensable first step: which code, if any, and what it entails.
- Obtain any documents given at the border, and note the date and place of the refusal.
- Decide the route. An unpaid fine may be resolvable administratively. A time-limited ban may simply have to run. An assessment-based code may be challengeable before the administrative court.
- Consider a visa with an annotation. Where there is a genuine, documented reason to enter — medical treatment, study, work with a permit, family unity, court proceedings — a consulate may issue a visa permitting entry notwithstanding a restriction.
- Do not simply try again. A second refusal is a second entry on the record.
Prevention, for future travel
- Check your record before travelling if you have ever overstayed, been refused, worked without a permit, or had a permit cancelled. The enquiry takes days.
- Calculate the ninety days correctly, on a rolling hundred-and-eighty-day basis, using an official calculator.
- Carry the evidence of your trip: return ticket, accommodation, means, and — where relevant — a letter explaining the purpose.
- Ensure passport validity well beyond your intended stay.
- Match the visa to the purpose. Travelling for work on a tourist visa is a refusal waiting to happen.
- Resolve old fines before they become a border conversation.
Frequently asked questions
Can I appeal at the airport? There is no effective on-the-spot appeal within the time before the return flight. Correcting a factual error immediately is the only realistic intervention.
Who pays for the return flight? The carrier is responsible for return; costs may be passed on depending on the circumstances and the ticket.
Will I be told the reason? Usually in general terms. The detail is established afterwards through a records enquiry.
Does a refusal mean a ban? Not automatically, but it is recorded and may generate or confirm a code.
Can I try another airport? No. The record is national.
Can a lawyer help while I am in transit? Sometimes, through immediate contact with the authority. Instruct early rather than after the flight is called.
How do I find out if I am at risk before travelling? A records enquiry, made in advance by a lawyer under a power of attorney.
Check before you fly
Almost every INAD case we see was foreseeable. The traveller had an old overstay, a refused application, or a period of unauthorised work, and had never checked what was recorded. The enquiry that would have prevented the trip costs days and no travel.
