What are the conditions for obtaining Danish citizenship?
An individual can obtain Danish citizenship in 2025 by naturalization if he meets the following criteria:
- Minimum residence: before applying, a foreign national needs to have resided in the country (with a valid residence permit in Denmark) for 9 consecutive years;
- Financial independence: financial independence for the last 2 years is also a criterion; during the last 5 years the applicant should not have applied for financial support for more than 4 months (in total);
- No debts: these refer to public debts for repayable benefits like that for child care, housing benefits, taxes, or more; one of our Denmark immigration specialists can provide more details;
- Citizenship test: this is a test that is mandatory and it includes questions about the Danish culture, society, and history; the examination takes place in two sessions each year;
- No crimes: this is an important criterion as applicants who have committed heavy crimes cannot apply for Danish citizenship.
Applicants who have attended university courses in Danish during their residence may be able to replace the language examination with the accreditation that proves their participation in these courses. It is important to note that the language exam is subject to a fee and that the applicant can take a mock examination online (which is recommended) before the official one.
Observing the criteria presented above is important for all applicants in 2025. We recommend reaching out to our immigration lawyer in Denmark before starting the application process in order to confirm that you qualify and comply with all of the ongoing requirements, including the valid residence permit in Denmark for the minimum number of years.
The video below is a summary of the main conditions for acquiring Danish citizenship:
Danish citizenship for citizens of Nordic countries
As mentioned above, some individuals might have some exemptions from the normal requirements of obtaining Danish citizenship through naturalization. This category includes Nordic citizens, namely citizens of Finland, Iceland, Norway, and Sweden.
This category can become Danish citizens by making a declaration to the Ministry of Immigration and Integration if they meet specific conditions:
- Be the age of majority (18) or older;
- Have acquired citizenship in Finland, Iceland, Norway, or Sweden through birth, adoption, or their parents’ marriage (not through naturalization);
- Be current residents in Denmark with seven years of continuous residency;
- Have no history of imprisonment or similar measures during this period.
Nordic citizens can ask for more details from our team if they are interested in moving to Denmark.
What is the general application process in 2025?
If you meet all of the criteria described above by our immigration lawyer in Denmark, you can start the application process with the Ministry of Immigration, Integration, and Housing. The main step is to fill in the application form and to provide the required documentation. This will include a passport copy, a copy of the permanent residence permit, the original Danish language examination results, copies of the Citizenship test or naturalization test results, and a filled-in statement for self-support. Parents may also need to submit a different statement for parental responsibility.
The application, if approved, is included by the Ministry in a bill and the Parliament needs to issue this bill (which takes place each year in two instances, in April, and in October). One of our agents who specializes in Denmark immigration can provide more details about the application procedure and the publication of the bill.
How fast can Danish citizenship be obtained?
As seen above, the process depends on the publication of a bill, which takes place each year. First of all, the date for obtaining Danish citizenship will depend on whether or not the applicant qualifies for one of bill publications for the Act of Naturalization. There are two distinct phases, the introduction of the bill (which takes place in April and October) and the passing of the bill which also takes several months (and it can occur in December or in June, for example).
The process in 2025 is a lengthier one because experts carefully assess each application. The estimated processing time for the applications is approximately 19 to 21 months from the time they are received by the Ministry of Immigration, Integration, and Housing. Our immigration lawyer in Denmark can provide updated information on the usual waiting time once the application has been submitted.
Dual citizenship in Denmark
The good news is that since September 1, 2015, dual citizenship in Denmark is allowed. Danish citizens who acquire citizenship in other countries through application or declaration are allowed to retain their Danish citizenship.
However, certain countries may have rules that require individuals to renounce their original citizenship to obtain citizenship in that country.
We can help you if you plan to immigrate to Denmark, and if you have questions regarding dual citizenship.
The 22-year rule in Denmark
The 22-year rule in Denmark applies to individuals who were born and raised abroad to Danish parents. According to the 22-year rule in Denmark, individuals who were born abroad, have never lived in Denmark, and have not established a significant connection to Denmark by the time they turn 22 will typically lose their Danish citizenship, unless losing it would make them stateless.
However, there is a provision for the Ministry of Immigration and Integration to grant a dispensation to retain Danish citizenship in certain cases, but this must generally be applied for before reaching the age of 22.
If you are in this situation, it is advised to seek support from our immigration lawyers in Denmark.
Reacquiring Danish citizenship
If you were previously a Danish citizen but lost your citizenship, you must meet certain residence requirements to reacquire Danish citizenship. Special rules apply if you have become a citizen of Finland, Iceland, Norway, or Sweden since losing your Danish citizenship.
If you do not meet the residence requirements, there is a transitional arrangement that allows you to reacquire Danish citizenship. This arrangement is only available if you lost your citizenship in connection with becoming a citizen of another country and have not been sentenced to an unconditional prison term since losing your Danish citizenship. The agreement started on July 1, 2021, and will remain in effect until June 30, 2026.
Our team can provide more details regarding immigrating to Denmark and acquiring or reacquiring citizenship.
Danish citizenship by marriage and investment
Denmark does not offer direct citizenship through investment, but investors can pursue a Startup visa, granting a renewable two-year residence permit. However, please remember that Danish citizenship can only be obtained after residing in Denmark for a continuous period of nine years.
For those seeking Danish citizenship through marriage to a Danish citizen, specific conditions apply. Spouses of Danish citizens may become citizens after 6-8 years of continuous residence, depending on their marriage duration. The marriage must be legal, voluntary, and recognized by Danish authorities. Additionally, applicants must hold a permanent residence permit in Denmark.
Danish citizenship for children born abroad
The child’s citizenship status is determined by the Danish nationality law in place at the time of their birth. Before July 1, 2014, if only the father was a Danish national, the child had to be born in wedlock to acquire Danish citizenship at birth.
However, starting from July 1, 2014, if one parent is Danish, a child gets Danish citizenship at birth, regardless of marital status or birthplace. The child also obtains Danish citizenship if the co-mother is Danish.
Additionally, children born out of wedlock to a Danish father and a foreign mother between October 11, 1993, and June 30, 2014, have the option to apply for Danish citizenship.
You can also contact our immigration lawyers in Denmark if you are in this situation.
