Brunei Citizenship Requirements
Ordinary naturalisation in Brunei has a long residence baseline, Malay-language assessment and a discretionary grant. Registration for other cohorts and possession of permanent residence are not themselves naturalisation.
Twenty years within twenty-five, plus the final two
Section 8 requires at least twenty aggregate years of residence during the twenty-five years immediately before application, including residence throughout the final two years. Meeting that calculation does not create an entitlement to a certificate.
Temporary passes are not automatically qualifying residence
Unlawful residence and specified custody periods are excluded. Temporary-pass or permit stays also do not count unless His Majesty consents. The Act credits specified absences, including approved education and qualifying government service, so a simple total of entry stamps is insufficient.
Capacity, character, support and permanent intention
The applicant must have full capacity, defined as at least eighteen and of sound mind, satisfy the good-character requirement, be unlikely to become a charge on Brunei and declare an intention to settle permanently. These conditions accompany the residence requirement.
Malay knowledge and speaking proficiency are assessed
The Language Board must find the prescribed Malay knowledge and proficient speech, with the Act's exception for inability caused by a physical, speech or hearing impediment. The regulations assess practical communication appropriate to the applicant's standing; they do not specify a CEFR level.
The oath and later foreign nationality matter
The prescribed oath renounces foreign loyalty and the exercise of rights belonging to another nationality. Separately, voluntary acquisition of another nationality causes loss of Brunei status under section 9(5)(a). This is not a promise that an ordinary naturalised person may freely retain or exercise another nationality.
Form E1, a discretionary decision and the oath
The regulations prescribe Form E1 for section 8 applications and Form E2 for the certificate. His Majesty may grant the certificate; the Act requires the allegiance oath and does not turn a completed form into approval. Its section 13 also limits reasons and review of the decision.
Scope and limitations
- The current AGC register supplies the 2011 Act and 2002 regulations. Those edition dates are not represented as 2026 enactments. Operational form, interview and documentary requirements must be reconfirmed with Immigration.
- The oath is not described here as proof that a foreign authority has already cancelled an earlier nationality. Other countries' retention rules and Brunei's deprivation provisions require separate assessment.
- The Act also addresses loss after five continuous years abroad without a substantial connection and an advance certificate procedure under section 9(1)-(3); citizenship should not be treated as an unconditional lifetime status regardless of later circumstances.
Next review due . An official update can change these requirements sooner.
