Danish citizenship: requirements and dual nationality
Short answer
Danish citizenship does not follow automatically after a set number of years. Naturalisation involves several requirements. Denmark allows dual citizenship, but the law of your other country also matters.
Current position, checked 11 November 2026: the responsible authority states that naturalisation applications are not being processed until the applicable conditions are clarified. An older processing-time estimate should therefore not be treated as a promise.
Residence and citizenship are separate
Residence permission provides rights under immigration rules. Citizenship is a different legal status. A CPR number, Danish employment or permanent residence does not itself prove Danish citizenship.
Identify your applicant category first. Certain Nordic citizens and former Danish citizens may qualify through declaration procedures. Someone who already acquired citizenship through a parent may need guidance on proof or retention rather than a standard naturalisation application.
What do the published conditions cover?
The published guidance normally requires nine years of continuous residence and at least two years of permanent residence at the relevant stage. Exceptions exist, and time outside Denmark can affect the calculation.
Other conditions concern self-support, employment, Danish language skills, knowledge of Denmark, certain public debts and criminal matters. Passing a language test therefore does not complete the entire process. Review the full official checklist even after a long period of residence.
Read those published conditions alongside the current processing notice. This guide cannot establish what rules will apply when an individual application is considered.
Prepare records rather than predicting a completion date
Create a chronology of your residence, absences, permanent status, employment and relevant tests. Compare it with supporting documents. This can reveal missing periods before you begin an application.
Check the current application instructions before submitting or paying a fee. If you believe an exception applies, explain and document its basis. Do not assume that requirements missing at submission can simply be completed while the application waits.
Can you keep another citizenship?
Denmark has accepted dual citizenship since 1 September 2015. Danish acceptance does not override another country's nationality law. Ask the other country's authorities whether acquiring Danish citizenship affects the nationality you already hold.
Possessing two passports does not settle every question about nationality status. Former Danish citizens and Danish citizens born abroad should check the specific recovery or retention rules relevant to them.
