01Who qualifies

Who qualifies, generation by generation

LIKELY

Can you claim Icelandic citizenship through a parent?

Citizen by birth (Art. 1)

A child of an Icelandic parent is Icelandic from birth. Born abroad, you keep it past 22 by living in Iceland or applying to the Directorate of Immigration to keep it before then.

What changes the answer

  • POSSIBLE
    If someone in the line became a citizen of another country before the next person in the line was bornCitizen by birth

    Iceland has accepted dual citizenship since Act 9/2003. Whether your parent was still Icelandic when you were born turns on the date and terms of their naturalization.

  • UNLIKELY
    If you were born before 2018Citizen by birth (Art. 1, older rules)

    Born abroad before 1 July 2018 to an Icelandic father, you were Icelandic at birth only if your parents were married; otherwise citizenship followed only through their later marriage or a notification under the rules then in force. The current Act gives no declaration route to repair it.

  • UNLIKELY
    If the parent is your mother and you were born before 1982Citizen by birth (Art. 1, older rules)

    Born before 1 July 1982 to an Icelandic mother married to a foreign father, you were not Icelandic at birth, and the current Act gives no declaration route to repair it. Unless the family registered you under the rules then in force, the road to Iceland is residence.

  • POSSIBLE
    If the parent is your mother and you were born between 1982 and 2004

    A child of an Icelandic parent is Icelandic from birth, but citizenship lapses at 22 for those born abroad who never lived in Iceland, unless retention was granted first, and the Act gives no declaration route to get it back. Whether yours survived is the question.

If someone in the line became a citizen of another country before the next person in the line was born, 2 more cases
  • UNLIKELY
    If you were born before 2003

    Before 2003 an Icelander who became a citizen elsewhere was generally released from Icelandic citizenship, so it did not pass to a child born afterwards, and the Act offers no declaration route for that child. The road to Iceland is residence and naturalisation.

  • UNLIKELY
    If the parent is your mother and you were born before 2003

    Before 2003 an Icelander who became a citizen elsewhere was generally released from Icelandic citizenship, so it did not pass to a child born afterwards, and the Act offers no declaration route for that child. The road to Iceland is residence and naturalisation.

UNLIKELY

Can you claim Icelandic citizenship through a grandparent?

No grandparent route

Icelandic citizenship passes only from a parent who held it at your birth. A parent born abroad usually lost it at 22, and anyone who naturalized elsewhere before 2003 was generally released, so grandparent lines rarely survive. The Act has no route for descendants of emigrants; the road to Iceland is residence and naturalisation.

What would settle itWhether your parent is still Icelandic (a current passport, or a retention decision before 22); if so, you are the child of an Icelandic parent and the parent rule applies.

UNLIKELY

Can you claim Icelandic citizenship through a great-grandparent?

No grandparent route

Icelandic citizenship passes only from a parent who held it at your birth. A parent born abroad usually lost it at 22, and anyone who naturalized elsewhere before 2003 was generally released, so grandparent lines rarely survive. The Act has no route for descendants of emigrants; the road to Iceland is residence and naturalisation.

What would settle itWhether your parent is still Icelandic (a current passport, or a retention decision before 22); if so, you are the child of an Icelandic parent and the parent rule applies.

02Dates that matter

The dates that matter

  1. 1982
    1 July 1982

    A child of an Icelandic mother married to a foreign father acquired citizenship at birth only from 1 July 1982; earlier births did not, and could only be corrected under the transitional rules or by general application. Ísland.is: citizenship for children of Icelandic citizens

  2. 1998
    1 October 1998

    A child born abroad to an unmarried Icelandic father did not acquire citizenship at birth; it followed if the parents married while the child was under 18, or, for births between 1 October 1998 and 17 April 2007, if the father gave notice before the child turned 18. Ísland.is: citizenship for children of Icelandic citizens

  3. 2018
    1 July 2018

    Since 1 July 2018 a child acquires Icelandic citizenship at birth if a parent is an Icelandic citizen; the rule is not retroactive. Icelandic Nationality Act No. 100/1952 (lög um íslenskan ríkisborgararétt), consolidated, Art. 1 (Act 61/2018)

03Mothers’ lines

How mothers’ lines were treated

In Iceland’s rule, the answer changes when the line runs through a woman:

  • UNLIKELY
    If the parent is your mother and you were born before 1982Citizen by birth (Art. 1, older rules)

    Born before 1 July 1982 to an Icelandic mother married to a foreign father, you were not Icelandic at birth, and the current Act gives no declaration route to repair it. Unless the family registered you under the rules then in force, the road to Iceland is residence.

  • POSSIBLE
    If the parent is your mother and you were born between 1982 and 2004

    A child of an Icelandic parent is Icelandic from birth, but citizenship lapses at 22 for those born abroad who never lived in Iceland, unless retention was granted first, and the Act gives no declaration route to get it back. Whether yours survived is the question.

In the law’s words

04Keeping your citizenship

Dual citizenship with your home country

You keep your citizenship.

On every open route, the rule lets a citizen of the United States, Canada, the United Kingdom, Australia, New Zealand, Brazil, Argentina or South Africa keep that citizenship.

05The routes

Every route, and the law behind it

Citizen by birth (Art. 1)

Open through a parent

  • LIKELY
    Through a parent
  • POSSIBLE
    Through a parent, if the parent is your mother and you were born between 1982 and 2004

The law

What would settle an unsure case

  • Whether you had legal domicile in Iceland, or a retention decision, before you turned 22; if not, the route back is residence-based naturalisation.

Citizen by birth

Open through a parent

  • POSSIBLE
    Through a parent, if someone in the line became a citizen of another country before the next person in the line was born

The law

What would settle an unsure case

  • Your parent's naturalization date against Act 9/2003 and against your birth, and whether they were formally released.
  • Whether your parent was formally released from Icelandic citizenship or kept it; the National Registry (Þjóðskrá) record would show it.

Citizen by birth (Art. 1, older rules)

Closed: no open answer on this route

  • UNLIKELY
    Through a parent, if you were born before 2018

    Born abroad before 1 July 2018 to an Icelandic father, you were Icelandic at birth only if your parents were married; otherwise citizenship followed only through their later marriage or a notification under the rules then in force. The current Act gives no declaration route to repair it.

  • UNLIKELY
    Through a parent, if the parent is your mother and you were born before 1982

    Born before 1 July 1982 to an Icelandic mother married to a foreign father, you were not Icelandic at birth, and the current Act gives no declaration route to repair it. Unless the family registered you under the rules then in force, the road to Iceland is residence.

The law

What would settle an unsure case

  • Whether your parents married before you turned 18, or your father gave notice in time; if so, the 22-year rule decides whether it survived.
  • Whether you were registered as an Icelandic citizen in the National Registry under the 1982 transitional rules; if so, the 22-year rule decides whether it survived.

No grandparent route

Closed: no open answer on this route

  • UNLIKELY
    Through a grandparent

    Icelandic citizenship passes only from a parent who held it at your birth. A parent born abroad usually lost it at 22, and anyone who naturalized elsewhere before 2003 was generally released, so grandparent lines rarely survive. The Act has no route for descendants of emigrants; the road to Iceland is residence and naturalisation.

The law

What would settle an unsure case

  • Whether your parent is still Icelandic (a current passport, or a retention decision before 22); if so, you are the child of an Icelandic parent and the parent rule applies.

06The documents

The documents, as the rule lists them

Citizen by birth (Art. 1)

Through a parent

  • Your parent's Icelandic passport or National Registry record
  • Your birth certificate

Through a parent, if the parent is your mother and you were born between 1982 and 2004

  • Your parent's Icelandic passport or National Registry record
  • Your birth certificate
  • Any retention decision or Icelandic passport issued to you

Citizen by birth

Through a parent, if someone in the line became a citizen of another country before the next person in the line was born

  • Your parent's naturalization certificate
  • Your birth certificate

Most countries also want proof that no one in the line became a citizen elsewhere before the next birth: the naturalization record with its date, or a letter that none exists.

07What it takes

What it takes: time, cost, the hard part, who decides

Citizen by birth (Art. 1)

Time
4–8 weeks for a first Icelandic passport once citizenship is confirmed; longer if the Art. 12 retention question needs the Directorate of Immigration's decision first.
Cost
About $200–400: certified copies, apostilles and the passport fee.
The hard part
If you were born abroad and are past 22, showing legal domicile in Iceland, or a retention application filed before then; the Act gives no route back once it lapses.
Who decides
The Icelandic consulate for your address, or the Directorate of Immigration (Útlendingastofnun) for an Art. 12 retention decision.
The first record
Your parent’s entry in the Icelandic national register (Þjóðskrá), from Registers Iceland (Þjóðskrá Íslands). Request a certificate from Registers Iceland with the name and kennitala if known; for entries before Þjóðskrá’s 1953 founding, the National Archives (Þjóðskjalasafn Íslands) holds the older parish registers. skra.is

How it’s filed

Where
The Directorate of Immigration (Útlendingastofnun), through the Icelandic embassy or consulate for your address office list
How
In person; no appearance needed
Fee
No fee
Decision
1–8 months
What goes in the file (4)
  1. Your parent's Icelandic national-register record or passport history
  2. Your own birth certificate
  3. Your parents' marriage certificate, if any
  4. Evidence of ties to Iceland, if you are past 22 and were born abroad
What goes wrong (1)
  • An Art. 12 retention application filed before 22 is free; once citizenship has lapsed, the Act gives no declaration route back and the family faces ordinary naturalisation instead.

Checked 26 September 2026 · source ↗

Citizen by birth

Time
3–6 months once the naturalization dates are documented; this is the rule applying to a parent who naturalized on or after Act 9/2003.
Cost
About $200–500 in certified copies and translations.
The hard part
Fixing the exact date and terms of your parent's naturalization abroad against Act 9/2003 and against your birth, and whether they were formally released from Icelandic citizenship.
Who decides
The Icelandic consulate for your address.
The first record
Your parent’s entry in the Icelandic national register (Þjóðskrá), from Registers Iceland (Þjóðskrá Íslands). Request a certificate from Registers Iceland with the name and kennitala if known; for entries before Þjóðskrá’s 1953 founding, the National Archives (Þjóðskjalasafn Íslands) holds the older parish registers. skra.is

What goes in the file (3)
  1. Your parent's Icelandic national-register record
  2. Your parent's naturalization certificate abroad, with its date and terms
  3. Your own birth certificate
What goes wrong (1)
  • This is the post-2003 case: whether your parent was formally released from Icelandic citizenship on naturalising abroad, or kept it under Act 9/2003, is the question the Directorate decides.
