Dual nationality in Sweden (2026)

In short: Sweden allows dual and multiple nationality. Naturalisation does not require giving up the previous nationality, and a Swedish citizen who acquires another nationality can keep Swedish citizenship.

| Loss of nationality on acquiring a foreign nationality: detailsNationality rules | A Swedish citizen who becomes a citizen of another country can keep Swedish citizenship. Loss by operation of law applies to a person born abroad who has never lived in Sweden, at the age of 22, unless they apply to keep it. Release from Swedish citizenship is possible on application.

Notes
- Stricter naturalisation rules (eight years of residence, a self-support requirement and a knowledge requirement) have applied since 6 June 2026; they do not change the rule on dual nationality.
- Migrationsverket says a Swedish citizen who becomes a citizen of another country 'can be allowed to keep' Swedish citizenship, and notes that some countries do not allow dual nationality.
