Citizenship by descent

Children of at least one Swedish parent are citizens by descent. If born abroad, registration is required at a Swedish embassy or consulate. In 2025, digitalised systems allow parents to register births and citizenship applications online, reducing waiting times significantly.

Documents checklist

• Valid passport or residence permit
• Birth and marriage certificates (translated if necessary)
• Proof of residence and tax compliance in Sweden
• Language and civic test certificates
• Employment or income statements
• Police clearance certificate
• Completed application via Migrationsverket portal

Costs and timelines

In 2025, the application fee for Swedish citizenship is SEK 1,500. Processing times average 12–24 months for naturalisation, 12–18 months for marriage-based applications, and less than 6 months for descent. Nordic citizens benefit from accelerated decisions within 2–3 months.

Language and integration requirements

Applicants must demonstrate integration by passing both the språkprov (language test) and samhällskunskapstest. These requirements ensure applicants can communicate effectively and understand Swedish society. Failure to pass these tests is a common reason for rejection.

What changed in 2025

• Stricter standards for the language test, requiring at least B1 proficiency.
• Expanded civic knowledge syllabus including digital rights and sustainability.
• Mandatory online submission of all applications via Migrationsverket.
• Faster digital registration for children born abroad to Swedish parents.
