SIS Alerts and Entry Bans – What Do They Mean and How Can They Be Removed?

2 October 2026

Re-entry bans, SIS alerts and SIS registrations – what do they actually mean, and how can a registration in the Schengen Information System be removed?

Receiving a return or removal decision, a re-entry ban or a registration in the Schengen Information System (SIS) can have far-reaching consequences, whether you are currently in Sweden or attempting to enter the Schengen Area.

For some people, the situation arises following a decision by the Swedish Migration Agency or a court. For others, the problem only becomes apparent at the border when they are refused entry.

In either case, the decision may affect your ability to stay in Sweden or elsewhere in the Schengen Area, return after travelling abroad, obtain a visa or residence permit, or cross a Schengen external border.

At the same time, it is often unclear what the different decisions and SIS registrations actually mean, how they relate to each other and what legal options are available.

Terms such as "SIS ban", "SIS block" and "SIS marking" are often used informally. Legally, however, it is important to distinguish between a re-entry ban, an SIS alert on return, and an SIS alert for refusal of entry and stay.

What is a re-entry ban?

A re-entry ban is a formal decision preventing a person from returning during a specified period following a refusal of entry, removal or expulsion decision.

For ordinary administrative re-entry bans under Swedish immigration law, the ban may generally be imposed for a maximum of five years. A longer period may be imposed where the person is considered to constitute a serious threat to public order or security.

Different rules apply where a person has been expelled from Sweden because of a criminal conviction. In such cases, a re-entry ban may be considerably longer and, in serious cases, may be imposed without a time limit.

The period of a re-entry ban normally begins when the person leaves the territory covered by the relevant return rules, rather than simply from the date on which the decision was issued.

A re-entry ban can significantly affect your ability to travel, work, visit family or apply for a visa or residence permit within the Schengen Area.

Once the re-entry ban becomes effective, it will normally form the basis for an alert in the Schengen Information System for refusal of entry and stay.

What is a SIS alert for refusal of entry and stay?

A SIS alert for refusal of entry and stay is a registration in the Schengen Information System informing authorities that a third-country national is to be refused entry or stay.

This is what is often informally referred to as a "SIS ban" or "SIS block".

Such an alert may, among other things, be based on a re-entry ban. SIS alerts may also be entered in certain cases involving public order, public security or national security.

Because SIS can be accessed by competent authorities throughout the Schengen system, the consequences are not limited to Sweden. A valid alert for refusal of entry and stay will normally result in the person being refused entry into the Schengen Area.

There are, however, exceptions and special procedures in certain situations, for example where the person holds a valid residence permit or long-stay visa issued by another Member State, or where rights under EU free movement law are involved.

If the underlying re-entry ban or other decision is withdrawn or annulled, the corresponding SIS alert must normally also be deleted.

What is a SIS alert on return?

An alert on return is different from an alert for refusal of entry and stay.

When a third-country national is subject to a return decision, information about that decision is normally entered into SIS. The purpose is to allow authorities to verify whether the person has complied with the obligation to leave and to support enforcement of the return decision.

An alert on return does not in itself constitute a re-entry ban.

When the person leaves the relevant territory and the departure is confirmed, the alert on return should normally be deleted without delay.

If the return decision is also accompanied by a re-entry ban, the return alert is normally replaced by or followed by an alert for refusal of entry and stay, so that the re-entry ban can be enforced.

This distinction is important. Leaving Sweden or the Schengen Area may therefore remove an alert relating to the obligation to return, while a separate SIS alert based on a re-entry ban may remain in place.

I have left Schengen, but my SIS registration is still there – what can I do?

In many cases, departure through a Schengen external border is registered electronically and communicated to the authority that issued the return decision.

However, errors and delays can occur.

If an alert on return remains in SIS even though you have complied with the return decision and left the relevant territory, it may be necessary to provide evidence of your departure and request that the registration be deleted.

Evidence may include, depending on the circumstances:

• Passport stamps

• Boarding passes or travel documents

• Evidence of entry into a country outside the Schengen Area

• Other documentation showing when and how you left

A person who can demonstrate that they left in accordance with the return decision can request that an obsolete return alert be deleted.

Can a re-entry ban and SIS alert be removed?

In certain cases, yes.

Under Swedish law, a final re-entry ban may be wholly or partially revoked if there are special reasons why the ban should no longer apply.

An application for revocation is normally submitted to the Swedish Migration Agency. Which authority ultimately has the power to revoke the ban can depend on which authority or court originally issued it.

Because an SIS alert for refusal of entry and stay may be based directly on the re-entry ban, successfully having the underlying ban revoked can also result in the SIS alert being deleted.

Whether there are sufficient grounds for revocation depends on the circumstances of the individual case.

Relevant factors may include:

• Family ties to Sweden or another Schengen country

• Children or a spouse living in Sweden or elsewhere in Europe

• Significant changes in circumstances since the original decision

• Compliance with the return decision

• The purpose and necessity of future travel

• Residence rights or a residence permit in another European country

• EU free movement rights

• The reasons why the re-entry ban was originally imposed

A successful application normally requires both a clear legal argument and documentary evidence supporting the circumstances relied upon.

Can incorrect information in SIS be corrected or deleted?

Yes.

A person registered in SIS has data protection rights, including the right to request information about personal data registered in the system and, where appropriate, to request that incorrect or unlawfully stored data be corrected or deleted.

This is a separate issue from applying to have a legally valid re-entry ban revoked.

If the SIS registration is based on an existing and legally valid decision, it is normally necessary to address the underlying decision itself. If the registration is incorrect, outdated or should already have been deleted, it may instead be possible to request rectification or deletion of the SIS data.

In Sweden, these issues are primarily handled by the Swedish Police Authority and, in certain cases, the Swedish Migration Agency.

Why contact AdamLaw?

At AdamLaw Juristbyrå, we regularly handle cases involving SIS alerts, re-entry bans, refused entry to the Schengen Area and EU immigration law.

We can assist with, among other things:

• Applications to revoke or partially revoke a re-entry ban

• Legal assessment of SIS alerts and their underlying decisions

• Requests concerning incorrect or outdated SIS registrations

• Evidence showing that a return decision has been complied with

• Legal strategies concerning residence permits in Sweden or another Schengen country

• Cases involving family ties or EU free movement rights

The correct legal strategy depends on why the SIS alert was entered, which country entered it and which underlying decision remains in force.

It is therefore important to identify the exact type of SIS registration before deciding which legal action to take.
