Dutch citizenship: naturalisation, family routes and retaining other nationalities

Nationality, partners & family

Dual nationality

Naturalisation generally requires renouncing prior nationality unless an applicable exception is established. Other nationality laws and later Dutch loss rules must also be checked.

[1][2]

Naturalisation

Normally five consecutive years lawful residence plus qualifying status, identity, integration and public-order conditions. Current IND main guide updated 28 August 2026; proposed changes are not substituted for these conditions.

[1]

Citizenship through marriage

Specified three-year partner exceptions exist, with cohabitation and continuing-relationship conditions. Marriage itself does not grant nationality.

[1]

Marriage & partner recognition

Domestic recognition

Same-sex marriage is permitted.

Immigration & nationality

Partner residence covers marriage, registered partnership and qualifying unmarried relationships subject to the route requirements.

[1][2]

Who can be included?

Family member	Age / eligibility	Conditions & route	Sources
Spouse / registered or qualifying unmarried partner	Normally both 21 or older; specific 18-year exceptions	Prove the relationship, shared residence and applicable resources/status. A partner of a highly skilled migrant is generally free to work under the issued family permission.	[1]
Children	Under 18; part of the household and not an independent family	Parentage, custody and consent from another custodial parent matter. The child is to live with the parent; the route is not an automatic inclusion of independent adult children.	[1]
Adult children / parents / other relatives	Not included by the ordinary minor-child or partner category	An independent or exceptional family route must be separately established. No general age-free dependent-relative entitlement is inferred from the skilled-migrant permission.	[1][2]

Nationality is a separate legal outcome

The official routes include automatic acquisition under nationality law, option for specified connections and naturalisation. Being born in the Netherlands or buying property should not be treated as a universal grant of nationality. Establish parentage, dates and legal status if a descent or recognition route may apply.

For most relocating adults, the naturalisation route is the relevant long-term question. Use current IND conditions rather than a proposed political change or an old account of the process. The cited main IND page was updated 28 August 2026.

Ordinary naturalisation and the process

The current ordinary requirement is at least five consecutive years lawful residence, timely extensions and qualifying status at application, throughout the process and at the ceremony. Identity/nationality evidence, integration and public-order requirements also apply. The ordinary starting point is adulthood; children can have distinct associated procedures.

The application is made through the municipality, with IND assessment. IND states a 12-month decision period, which is not a promise that the entire preparation-to-passport process takes 12 months. Obtain the foreign civil documents and determine legalisation, translation and integration evidence before the appointment.

A Dutch partner can change the residence period

IND describes specific three-year exceptions for a person living with the same Dutch partner, including qualifying marriage/registered partnership and certain unmarried cohabitation cases. The required residence history and continuing relationship matter; marriage itself does not confer citizenship.

An application from abroad has different conditions, and a person’s own country-of-nationality connection can matter. Use the precise exception matching the relationship and history. Keep evidence of cohabitation and status rather than relying only on the date of the wedding.

Integration and renunciation deserve early attention

IND’s current integration page accepts the applicable civic-integration evidence at A 2 or higher, with defined exemptions and dispensations. That is a condition to verify for the individual, not a guarantee that every existing certificate will qualify.

Naturalisation often requires renouncing the former nationality, subject to exceptions determined under the applicable rules. Relevant circumstances can include marriage to a Dutch citizen, inability to renounce and other statutory situations. Do not describe this as an unrestricted dual-citizenship programme; check both countries’ laws before making an irreversible nationality decision.

Family recognition and preserving nationality later

The Netherlands permits same-sex marriage. Relationship recognition, the correct immigration route and nationality eligibility remain separate questions; a foreign partnership’s legal form should be documented.

After nationality is obtained, retain awareness of loss rules. IND identifies potential loss for an adult dual national after 13 consecutive years outside the Kingdom and EU, subject to the detailed renewal/interruption rules and exceptions. Passport and nationality-certificate maintenance can therefore matter in a globally mobile life.
