Sweden amends constitution to allow revoking citizenship of dual nationals

Sweden’s parliament has approved a constitutional amendment that will allow laws to strip some dual nationals of Swedish citizenship. It creates a route to revoke citizenship in cases of improper acquisition or convictions for offences seriously harming Sweden’s vital interests.

The change takes effect on 1 January 2027, after the Riksdag’s second vote, following an initial approval in May. It applies only to people who hold another citizenship, and critics argue the “vital interests” wording is too vague and could leave dual nationals with less protection; supporters say it is intended for very serious cases.
