2. Pass the Norskprøve (language exam) and samfunnskunnskap (social studies test).
3. Prepare documents: income proof, tax compliance, and accommodation.

Citizenship by descent

Children of at least one Norwegian parent automatically acquire citizenship, whether born in Norway or abroad. Since reforms in 2021, registration procedures have been streamlined for children born overseas, allowing parents to file digitally through Norwegian consulates.

Documents checklist

• Valid passport or residence card
• Birth and marriage certificates (with translations if required)
• Proof of legal residence in Norway
• Language exam and social studies certificates
• Proof of income, tax records, and accommodation
• Police clearance certificate
• Completed UDI application forms

Costs and timelines

Application fees in 2025 average NOK 6,500. Processing times are typically 12–24 months for naturalisation, 12–18 months for marriage-based applications, and shorter for descent and Nordic citizens. Delays can occur if documents are incomplete.

Language and integration requirements

Applicants must pass the Norskprøve (oral and written Norwegian) and the samfunnskunnskap test, covering history, society, and laws. These requirements ensure integration into Norwegian society and are strictly enforced in 2025.

What changed in 2025

• New digital identity verification introduced for online applications.
• Higher language test standards, requiring B1 level in Norwegian for naturalisation.
• More robust checks on spousal applications to prevent fraudulent marriages.
