The Schengen Information System (SIS) concerns you directly, whether you are a national of a Schengen Member State or not.
If your visa was refused and/or you have reason to believe that your name appears in the SIS, do not hesitate to exercise your rights.
In Portugal, the right of access, correction or deletion, regulated by Act 2/94, of 19 February, is exercised by means of the CNPD.
Therefore, you may address your request to the CNPD, by using the following forms:
Attention: Please enclose a Consulate certified copies of your passport and of your residence permit (if applicable). The forms provided are a non-official translation. Please use the Portuguese version of the application forms. All documents presented to the CNPD must be in Portuguese or officially translated into Portuguese by the Consulate General.
Know your rights.
The Schengen Convention itself recognises the rights of individuals. These include:
The right to access information (alert) concerning you which is contained in the SIS; The right to correct data where there is a de jure or de facto mistake; The right to apply to the courts or competent authorities to demand that data be corrected, deleted or that damages be awarded; The right to ask for data to be checked and to question the use made of such data.
You may check your alert in the SIS in any Schengen Member State. The checks will be carried out in accordance with national legislation that applies in that Member State. For further information, you may consult the Guide to exercise your rights.
