If one of the child’s parents is an EU/EEA citizen and has a right of residence in Sweden, and your child is also an EU/EEA citizen, then they automatically have a right of residence. In that case, you do not need to contact the Swedish Migration Agency. For information about your child’s population registration, contact the Swedish Tax Agency.

If the parents are EU/EEA citizens and have a residence permit in Sweden, you must apply for a residence permit for your child.
