The Migration Agency takes fingerprints to check if you have applied for asylum in Sweden or another European country before. The same day that you are at the Application Unit the staff will take your parents' fingerprints. If you are 6 or older they will take your fingerprints too. If you are under 14 your fingerprints will not be used for any controls.
Fingerprints are taken when you press your fingers against a machine that reads your fingerprints.
The fingerprints are sent to several databases. One of these is in Sweden. In one database the Migration Agency can see if you have applied for asylum in Sweden before.
The European Union has another database called Eurodac. All of the EU countries, Iceland, Norway and Switzerland can see this database. If you have applied for asylum in one of these countries it will show up in the database. These countries are called the Dublin countries.
The European Union has another database called VIS. If you have applied for a permit at an embassy of any of the EU member states to travel to any of the EU countries, for example as a tourist or to visit relatives or friends, it will show in this database.
The European Union is called the EU. Sweden has been a member of the EU since 1995. 28 countries are members of the EU.
