Simon Montgomery's application to remain in Sweden, made when his son was six months old, was rejected in December by the migration agency on the grounds that there was no evidence he had "actual care" for the child, who at that point still stayed overnight with his mother. The agency also said he could maintain his relationship with his son from afar, since he can enter the country visa-free and "still have the opportunity to visit the child in Sweden".
Montgomery appealed, but the migration court this month sided with the authorities, assessing that the "state's interest in regulated immigration outweighs your interest in the protection of your private and family life in a proportionality assessment".
Montgomery, who said he grew up without his father in his life, said he was determined to be there for his newborn. He and his former partner, the boy's German mother, have legally recognised joint custody and a "stable parenting plan" agreed through the municipal family law service. He said he sees his son three days a week, takes an active part in his care, and that overnight stays are "about to start very soon".
"Everything in Sweden is about the children's right to both parents," he said. "But this seems to be ignoring all of that, when it comes around to immigration."
His lawyer argued that forcing him to leave "would undermine the process and create instability for his son", who is "in a critical attachment phase" and would benefit from both parents being physically present. The boy's mother does not have a family network in Sweden to rely on, the lawyer said, and deportation would constitute a disproportionate interference in family life, violating article 8 of the European convention on human rights.
Montgomery said he cannot visit his 98-year-old grandmother in the UK for fear of being blocked from returning to Sweden. "It's almost like torture in some ways," he said.
Montgomery moved to Sweden after Brexit, so he is not entitled to withdrawal agreement residency rights. Sweden's migration agency was approached for comment. The German government said it could not comment on the case.
