At Copernica Law, we are proud to help clients navigate even the most complex immigration challenges. As an immigration law specialist, we know that some cases require legal precision, strategic advocacy, and an in-depth understanding of European immigration systems. This recent success story is a perfect example of how the right legal approach can completely change a person’s future.
We are pleased to share the story of one of our clients who came to us with a serious and life-changing problem: a SIS alert issued by the Danish Immigration Service. Due to this registration in the Schengen Information System (SIS), another EU country, Portugal, was legally unable to grant him a residence permit in Portugal, even though he met all the requirements. For him, the SIS alert was not just an administrative problem; it was a barrier that put his entire life on hold.
The challenge: A SIS alert blocks a new life
When our client contacted us, he was stuck in a frustrating situation. He had applied for a residence permit in Portugal, met all the criteria, and was ready to begin a new chapter in a new country. The Portuguese authorities, however, gave a clear message: We cannot issue your residence permit while a SIS alert from Denmark remains active.
The SIS system is shared across all Schengen countries. If one country enters a person as an alert, such as a refusal of entry or residence – other member states are legally obliged to refuse a residence permit until the SIS alert is deleted. This meant that even though Portugal had no objections to our client, the Danish SIS registration blocked him.
Our legal strategy: Challenging the SIS entry
At Copernica Law, we immediately began a thorough review of the case. SIS alerts are serious, but they are not permanent if they are issued incorrectly, disproportionately, or without legal justification. After analysing the details, we concluded that there was a strong legal basis for challenging the Danish SIS alert.
Our team prepared a structured submission, in which we argued why the SIS entry should be removed. We presented evidence, legal arguments, and procedural considerations showing that:
- The SIS alert prevented the client from exercising his rights in another EU country,
- The entry was no longer necessary, proportionate, or justified under EU law,
- The continued presence of the alert created an unreasonable barrier to a residence permit in Portugal.
With careful preparation and persistent follow-up, we pushed for the SIS alert to be deleted from the Danish system.
The breakthrough: SIS alert deleted
After reviewing our arguments and documentation, the authorities agreed to remove the SIS alert. This was the turning point.
Once the SIS entry had been deleted from the Schengen Information System, the situation changed overnight. Portugal, no longer legally restricted by another country’s alert, could finally approve the client’s residence permit. Shortly afterwards, our client received the good news: his residence permit had been issued by the Portuguese authorities.
What had once been an uncertain and stressful situation became a clear path forward. With the administrative barrier gone, he could finally move on with his life in Portugal.
Why this case matters: A system that must be cleared first
This success story highlights an important but often overlooked reality:
- European authorities cannot issue a residence permit if a SIS alert from another Schengen country is active.
- Even if a person is eligible for residence, meets all criteria, and has a valid reason to reside in a new EU country, any SIS alert acts as a complete legal block – until it is resolved.
- In many cases, people are not aware that such alerts even exist. Others assume that a new EU country will overlook it if they meet the requirements for a new residence permit in a new EU country.
That is why professional legal help is crucial. It takes expertise to understand the reason for the SIS alert, identify whether it can be challenged, and prepare the right arguments. For our client, the difference between delay and success was legal intervention at the right time.
At Copernica Law, we remain committed to guiding our clients through even the most complex international and European immigration law matters. No matter how difficult the starting point may seem, the right strategy can open doors again.
