Who qualifies for Icelandic citizenship by descent
You're Icelandic if a parent was Icelandic at your birth (subject to the rules for unmarried fathers at the time). There's no grandparent route. Born abroad and never domiciled in Iceland? Apply to retain citizenship between 18 and 22, or it ends on your 22nd birthday — unless that would leave you stateless.

The age-22 rule in Iceland
Under Article 8 of the Nationality Act, an Icelandic citizen born abroad who has never been domiciled in Iceland, and hasn't stayed there in ways that show ties to the country, loses Icelandic citizenship at 22. The way to avoid it is to apply to retain citizenship between your 18th and 22nd birthdays.
The rule never makes anyone stateless: if Icelandic is your only citizenship, you keep it.
Who is Icelandic by birth
A child of an Icelandic mother is Icelandic at birth. A child of an Icelandic father is Icelandic if the parents were married, or once paternity is established under the rules that applied at the time of the birth. Children of unmarried Icelandic fathers born before the reforms may not have acquired citizenship at birth; if that's you, ask the Directorate of Immigration about notification.
Iceland has no route through grandparents. The alternative is naturalisation after years of residence, with an Icelandic language requirement.
Fees from 2026
Iceland raised its citizenship fees on 1 January 2026: a citizenship application now costs ISK 60,000 (one fee covers an adult and children applying together), a child's application ISK 30,000, and a notification of citizenship ISK 30,000.

Step by step
1. Register your birth with Registers Iceland (Þjóðskrá), usually through the Icelandic embassy, so you have an Icelandic ID number. 2. Apply for an Icelandic passport. 3. If you were born abroad and have never been domiciled in Iceland, apply to the Directorate of Immigration to retain citizenship between your 18th and 22nd birthdays. 4. Keep proof of any time spent in Iceland — it helps show ties.
Dual citizenship since 2003
Before 1 July 2003, Icelanders who took another citizenship lost Icelandic citizenship. Since then they keep it, and foreigners naturalising in Iceland don't have to give up theirs. Former Icelanders who lost citizenship under the old rules may be able to regain it by notification — check the current conditions with the Directorate of Immigration.
Worked examples
Anna was born in Canada in 2004 to an Icelandic mother and a Canadian father and has never lived in Iceland. She is Icelandic from birth, but she must apply to retain citizenship before her 22nd birthday in 2026 or it ends.
Jón was born in the US to an American mother; his grandfather emigrated from Iceland. His father was never an Icelandic citizen. Jón has no claim by descent — Iceland passes citizenship only from a parent.

Where Icelandic claims go wrong
- Missing the retention window between 18 and 22

- Old guides giving dual citizenship as 31 December 2003 — it was allowed from 1 July 2003

Icelandic citizenship FAQ
Q1Do I lose Icelandic citizenship at 22?
Only if you were born abroad, have never been domiciled in Iceland, haven't stayed there in ways showing ties, and didn't apply to retain it between 18 and 22 — and never if it would leave you stateless.
Q2Can I be Icelandic and American?
Yes. Iceland has allowed dual citizenship since 1 July 2003.
Q3Can I claim Icelandic citizenship through a grandparent?
No. Icelandic citizenship passes only from a parent.
Q4What does a citizenship notification cost?
ISK 30,000 from 1 January 2026; a full citizenship application costs ISK 60,000.
Q5My father is Icelandic but wasn't married to my mother. Am I Icelandic?
It depends on the rules in force at your birth and whether paternity was established. Ask the Directorate of Immigration; if you didn't acquire it at birth, notification may be possible.
