According to Sweden's Migration Agency, it is possible, although only "in exceptional circumstances", for the parent of an adult from a non-EU country working in Sweden to get a residence permit to come and live with their adult child. If you have lived apart for too long, it is not usually enough for the Migration Agency for the child in Sweden to report that their parent is now suffering from health issues which require the care of the adult in Sweden. If the parent is a citizen of an EU country and has retired, they have the right to live in Sweden if they can show that they have sufficient funds, or income from a pension, to support themselves, according to the Swedish Tax Agency.
