Swedish nationality law determines entitlement to Swedish citizenship. Citizenship of Sweden is based primarily on the principle of jus sanguinis. In other words, citizenship is conferred primarily by birth to a Swedish parent, irrespective of place of birth. In general, children born in Sweden to foreign parents do not acquire Swedish citizenship at birth, although if they remain resident in Sweden they may become Swedish later on. Swedish law was significantly amended with effect from 1 July 2001 and from that date, dual citizenship is permitted without restriction.
Birth
A child born after 1 April 2015 acquires Swedish citizenship automatically if:
one of the parents is a Swedish citizen at the time of the child's birth
a deceased parent of the child was a Swedish citizen upon their death
A child born before 1 April 2015 acquired Swedish citizenship at birth if:
the child's father was a Swedish citizen and was married to the child's mother; or,
the child's father was a Swedish citizen, the child was born out of wedlock, and the child was born in Sweden; or,
the child's mother was a Swedish citizen and it was born on or after 1 July 1979.
For example, a child born to a Swedish father and a non-Swedish mother will not be Swedish if either: its parents are not married to each other or if they were not married when it was conceived and it was born outside of Sweden, unless the father sends notification to an embassy or consulate with the child's passport, birth certificate, proof of his own citizenship at the time of the birth, and a certificate of paternity. A child who is born abroad and whose father is a Swedish citizen will acquire Swedish citizenship when the parents get married, provided the child is aged under 18.
Older legislation
The law that governed the transmission of citizenship before the Citizenship Act of 2001 was the Citizenship Act of 1894, with intervening reforms in 1924, 1950, and 1979.
Adoption
A child who is aged under 12 and who has been adopted by a Swedish citizen automatically receives Swedish citizenship upon adoption if
the child has been adopted as the result of a decision taken in Sweden or in another Nordic Council country
the child has been adopted as the result of a decision taken abroad and approved in Sweden by the Swedish Intercountry Adoptions Authority
the adoption is valid under Swedish law.
The adoption must have been officially decided or approved after 30 June 1992. A child aged 12 or more at the time of adoption may acquire Swedish citizenship by application.
Naturalization as a Swedish citizen
Swedish citizenship can be acquired by naturalization, also known as citizenship by application. A foreigner may be granted Swedish citizenship upon meeting certain requirements, including:
holding a permanent residence permit, unless a citizen of a Nordic Council country. For citizens of European Economic Area nations, a right of residence or limited residence permits for five years equate to a permanent residence permit.
A number of exemptions apply to the residence period:
the residence period is reduced to 4 years for recognised refugees and stateless persons.
citizens of other Nordic Council countries are only required to have two years' residence in Sweden.
former Swedish citizens
those employed on Swedish ships
persons employed abroad by Swedish corporations
a person with previous long residence in Sweden
For those married to, living in a registered partnership with or cohabiting with a Swedish citizen, they can apply for Swedish citizenship after three years. In these cases, they must have been living together for the past two years. It is not enough to be married to one another, they must also live together. Sweden imposes no requirements on Swedish language abilities or knowledge about Swedish history or culture, the only other country in Europe without similar requirement is Ireland.
Citizenship by notification
Notification is a simpler method of acquiring Swedish citizenship. Those not eligible for notification may still be eligible for naturalisation by application. Categories of persons eligible for citizenship by notification include:
Stateless persons
A stateless person may acquire Swedish citizenship by notification if that person has a permanent resident permit and falls into one of the following categories:
born in Sweden and aged less than five;
aged under 18 and in the custody of a Swedish citizen;
aged 18 or 19 and resident in Sweden since age 15.
Young persons resident in Sweden
Swedish citizenship may be acquired by notification by young persons who hold a permanent resident permit in the following cases:
aged under 18 and resident in Sweden for three years
aged 18 or 19, where the person has been resident in Sweden since turning 15.
Former Swedish citizens
Former Swedish citizens who hold permanent resident permits may acquire Swedish citizenship by notification if the following conditions are fulfilled:
resident in Sweden for the 2 years preceding the application
Those former Swedish citizens who are citizens of other Nordic countries may acquire Swedish citizenship by notification immediately upon resuming residence in Sweden.
Citizens of Nordic countries
Citizens of other Nordic Council countries may be eligible for Swedish citizenship by notification in the following cases:
aged 18 or over
the other Nordic citizenship has been acquired other than by naturalisation
2 years' residence in Sweden
And a person who has lived in Sweden for 5 years, who can speak and write Swedish, can be qualified to obtain citizenship provided there is no criminal history.
Loss of Swedish citizenship
Although dual citizenship is permitted, a Swedish citizen who was born outside Sweden and is a citizen of another country will lose Swedish citizenship at age 22 unless he or she is granted approval to retain Swedish citizenship between ages 18–21. However, approval is not required if:
the person has ever been domiciled in Sweden; or
the person has ever been in Sweden under circumstances that indicate a link with Sweden.
In such cases the Swedish citizenship is retained.
Dual citizenship
With effect from 1 July 2001, a Swedish citizen acquiring a foreign citizenship does not lose Swedish citizenship. Former Swedish citizens who lost Swedish citizenship prior to this date were given a two-year period to re-acquire Swedish citizenship by declaration. Children of former Swedish citizens were also eligible to acquire Swedish citizenship by declaration. The deadline for submission of applications was 30 June 2003. The changes to the law also mean that foreigners seeking naturalisation as a Swedish citizen do not need to renounce their former citizenship. They may retain it if the law of the other country permits them to do so. Swedish citizens who nonetheless hold Japanese citizenship must normally, under Japan's nationality law, notify Japan's Ministry of Justice, before turning 22, whether to keep their Swedish or Japanese citizenship. Prior to 1 July 2001, Swedish citizens were still able to legally hold dual citizenship in certain circumstances, for example, if the other citizenship was acquired automatically at birth.
Visa requirements for Swedish citizens are administrative entry restrictions by the authorities of other states placed on citizens of Sweden. As of May 2018, Swedish citizens had visa-free or visa on arrival access to 187 countries and territories, ranking the Swedish passport third in the world according to the Visa Restrictions Index. The Swedish nationality is ranked seventh in The Quality of Nationality Index. This index differs from the Visa Restrictions Index, which focuses on external factors including travel freedom. The QNI considers, in addition, to travel freedom on internal factors such as peace & stability, economic strength, and human development as well.
