My Danish OH has now lived in the UK for 7 years and has no plans to return to Denmark. His passport expires next year and that and the recent referendum have made us think about whether it's worth him applying for British citizenship.
Are there any disadvantages to giving up his Danish citizenship and becoming a UK citizen? His current line of work, although based in the UK, means he works exclusively with Scandinavian countries thus jobs in the future may be based there. Would he be in a better position to take up a job in Norway for example, if he was to remain a Danish citizen?
