If one of your parents was a Swedish citizen when you were born, you may already hold Swedish citizenship by descent without ever having applied for it. Whether you got it automatically, need to file a notification, or need to act before a deadline depends on the date you were born and, for some periods, whether your parents were married. Sweden allows dual citizenship, so claiming it usually doesn’t cost you your current nationality.
Who Qualifies by Birth Date
Swedish citizenship law changed twice in ways that still matter today, so the rule that applies to you is the one that was in force on the day you were born.
Born on or After April 1, 2015
If either parent was a Swedish citizen at the time of your birth, you became Swedish automatically. Place of birth, parents’ marital status, and which parent held the citizenship don’t matter. No application is required.
Born Between July 1, 2001 and March 31, 2015
A Swedish mother passed citizenship to her child automatically in every case. A Swedish father passed it automatically only if he was married to the child’s mother at the time of birth. If the Swedish father was unmarried and the child was born abroad, citizenship did not pass automatically. In that situation, the father had to file a notification with the Swedish Migration Agency before the child turned 18. Later marriage of the parents while the child was under 18 and unmarried could also confer citizenship, through a process called legitimation.
Born Before July 1, 2001
The older rules were more restrictive, especially for children born outside Sweden, and the details depend on the exact year and family circumstances. If this is you, don’t try to sort it out on your own. Request a declaration of citizenship from the Migration Agency, which will apply the rules in force on your birth date and tell you definitively where you stand.
Adopted Children
A child under 12 adopted by a Swedish citizen becomes Swedish automatically if the adoption was decided in Sweden or another Nordic country, or if a foreign adoption was approved in Sweden by the Family Law and Parental Support Authority. The adoption decision must have been made after June 30, 1992.
The Age 22 Rule Can Take It Away
Here is the trap that catches people with Swedish parentage who grew up abroad. If you were born outside Sweden, have never lived in Sweden, and haven’t visited under circumstances that show a connection to the country, you lose your Swedish citizenship automatically on your 22nd birthday. No letter, no warning.
You keep it automatically only if one of these applies:
- Losing it would leave you stateless.
- You’ve lived in Denmark, Finland, Iceland, or Norway for a combined total of at least seven years.
- You’ve lived in Sweden at some point, or visited regularly enough to show a genuine connection.
If none of those fit, you have to apply to keep your citizenship between your 18th and 22nd birthdays. The application is free. You’ll use the form “Ansökan om att få behålla svenskt medborgarskap” (in Swedish only, from the Migration Agency) and file it with your nearest Swedish embassy or consulate, along with a copy of your passport or identity document and, if you have it, proof of Swedish citizenship.
Miss the window and the citizenship is gone. You can regain it, but only by moving to Sweden. Filing the retention application before 22 is far easier than the alternative.
Confirming Citizenship With a Declaration
If you’re uncertain whether you’re actually a Swedish citizen — because your parent’s status is unclear, or because the older rules are hard to read — you can request a declaration of citizenship from the Migration Agency. The declaration is a formal answer to that yes-or-no question, and it’s free.
The application is form 322011 (Swedish only). You submit it with certified copies of your identity document, your birth certificate (particularly if you were born out of wedlock), and your parents’ marriage certificate. If you live abroad, file it at a Swedish embassy or consulate. If you live in Sweden, mail it to Migrationsverket, Medborgarskapsenheten, 601 70 Norrköping.
Documents You’ll Need
Swedish authorities want originals or certified copies. The exact list varies with your situation, but most descent cases involve:
- Your birth certificate, showing both parents’ names. Some consulates ask for additional proof of birth for children born abroad, such as a hospital discharge summary or doctor’s statement.
- Proof that the Swedish parent is Swedish: a valid Swedish passport, a citizenship certificate, or an extract from the Swedish population register.
- Your parents’ marriage certificate, if the claim relies on marriage (particularly for pre-April 2015 births with a Swedish father).
- A paternity acknowledgment, if the parents weren’t married and the Swedish parent is your father.
- Your own valid passport or national ID card.
Documents must be in Swedish or English. Anything in another language needs a certified translation submitted alongside a copy of the original.
Foreign vital records, such as a U.S. birth certificate or marriage certificate, may need an apostille. Apostille requirements vary by consulate, so check with the office handling your case before submitting. In the United States, apostilles for vital records come from the Secretary of State in the state that issued the document.
Where to File and What It Costs
The Swedish Migration Agency decides every citizenship case. Where you drop off the paperwork depends on where you live.
- Outside Sweden: file at a Swedish embassy or consulate-general, which forwards the case to the Migration Agency.
- In Sweden: mail your papers to Migrationsverket, Medborgarskapsenheten, 601 70 Norrköping.
For a child born abroad before April 1, 2015 to an unmarried Swedish father and a foreign mother, the specific notification is form 318011 (Swedish only), and it must be filed before the child turns 18. The Migration Agency also has an e-service for some notification types; check the current list on their site.
Fees depend on the type of case:
- Citizenship application (adults): SEK 1,500 (roughly $160).
- Citizenship notification for a child: SEK 475 (roughly $50). No separate fee if the child is included in a parent’s own application.
- Declaration of citizenship: free.
- Retention application at ages 18–21: free.
How Long It Takes
Processing times reported by the Migration Agency, measured as the time within which 75 percent of decided cases are handled:
- Notification for children with a Swedish father born abroad before April 2015: about 8 months.
- Citizenship for children with a Swedish parent, general: about 13 months.
- Citizenship applicants aged 18 to 21: about 6 months.
- Adult citizenship applications: about 53 months.
That last figure isn’t a misprint. The adult application queue runs over four years. Notification-based descent claims move much faster because the Migration Agency is confirming a right that already exists rather than deciding eligibility from scratch.
After Your Citizenship Is Confirmed
Coordination Number First
Before a child born abroad can get a Swedish passport, they need a coordination number (samordningsnummer), which acts as a temporary personal identity number. Applying is free but must be done in person at a Swedish embassy or consulate, with the child present and at least one parent. You’ll need form SKV 7750 and a “Verification of Swedish Citizenship” form signed by the Swedish parent. Processing runs roughly 8 to 12 weeks, and you can’t file for the passport at the same time.
Then the Passport
Once you have a coordination number or personal identity number, you can apply for a Swedish passport at an embassy or consulate. A Swedish passport is also an EU passport, so it carries the right to live, work, and travel across EU and EEA member states. You can stay in any EU country for up to three months on a valid passport or national ID; longer stays require registering as a worker, self-employed person, or student.
Dual Citizenship Is Allowed
Sweden permits dual citizenship, so claiming Swedish citizenship by descent doesn’t require giving up your U.S. or other nationality. The United States likewise doesn’t require its citizens to renounce U.S. citizenship when they acquire another. If you hold both, you owe legal duties to both countries, and you must enter and leave the United States on your U.S. passport.
If You’ve Already Lost It
If your Swedish citizenship lapsed at 22, or you renounced it earlier, getting it back is possible but requires moving to Sweden. You must be at least 18, hold a permanent residence permit or equivalent status, have lived in Sweden for at least two years while registered in the Swedish Population Register, and not be under suspicion or conviction for certain serious offenses. The notification fee to regain citizenship is SEK 475.
Citizens of Denmark, Finland, Iceland, or Norway who lost their Swedish citizenship have a lighter path: currently living in Sweden and registered in the Population Register is enough.
There’s no way to regain Swedish citizenship from abroad. If you’re approaching 22 and still eligible, the free retention application is a much shorter road than the two-year residency route later.
