This law implements new European Union regulations on processing applications for international protection and determining which country is responsible for handling them. Key changes include shortening the appeal deadline for rejection of applications to seven days, and establishing a clear legal obligation for applicants to cooperate with authorities by providing information and attending interviews. The law also incorporates the European fingerprint database Eurodac, allowing authorities to register facial images and fingerprints of applicants aged six and over in a shared database. This affects anyone applying for international protection in Iceland or residing there unlawfully.
