The following 25 countries are members of the Schengen cooperation: Austria, Belgium, the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Slovakia, Slovenia, Switzerland, Portugal, Spain and Sweden.
Registration in SIS is on the condition the person has been expelled from Norway. Expulsion from Norway involves primarily that the person is registered in SIS and the person will thereby be denied entry to the entire Schengen area.
Anyone not a citizen of an EU or Schengen country (third country citizens) can, in principle, be registered in SIS. However, third country citizens with a valid permit in a Schengen country shall not be registered in SIS. This means that a person cannot hold a permit in a Schengen country while at the same time be registered in SIS (as a persona non grata).
In Norway, the Norwegian Directorate of Immigration (UDI) has the authority to make decisions concerning registration in SIS in the first instance. This decision is normally taken at the same time as a decision to expel that person from Norway. Decisions can be appealed to the Norwegian Immigration Appeals Board (UNE).
A ban on entry normally applies from the date the person leaves Norway. If the decision is first made after the person has left Norway, the ban on entry applies from the date the decision concerning expulsion and registration in SIS is made. A person who does not leave Norway despite there being a decision concerning expulsion, can be registered in SIS as soon as the final decision has been made (i.e. after any appeal has been heard and the appeal process is complete).
A person shall not be registered in SIS while at the same time holding a valid permit in a Schengen country. If Norway wishes to register a person who holds (or possibly holds) a permit in another Schengen country, the Norwegian Directorate of Immigration (UDI) will notify that country's authorities that the person in question has been registered in SIS. If UDI receive confirmation that the person in question holds a valid permit, the registration in SIS will be deleted.
Anyone the UDI has registered in SIS as persona non grata shall receive notification of such. Those registered in SIS have the right to know what information is registered and can demand any erroneous or incomplete information be corrected. Requests for access to, or correction or deletion of records can only be made by the person registered. A person has the right to compensation if he/she suffers a loss as a result of information registered or used in contradiction to the rules concerning handling of information in SIS. In Norway, a request for access to, or correction or deletion of records, or compensation shall be sent to the SIRENE office at the Norwegian National Criminal Investigation Service (KRIPOS/NCIS).
