# 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. Scope: Selected ordinary adult naturalisation requirements under section 8 of the Brunei Nationality Act. Birth, indigenous-group, marriage and registration routes are outside this baseline. Jurisdiction: Brunei Darussalam: nationality. Sources reviewed 2026-09-22; review due 2026-12-21. General information, not legal advice or a finding of eligibility. Requirements depend on the route, applicant and filing date. Verify the official instructions before applying. ## 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. Evidence: conditional.

Source location: Section 8(1)(a)-(b), printed pages 10-11, PDF pages 12-13. ## 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. Evidence: conditional.

These conditions accompany the residence requirement. Evidence: conditional.

The regulations assess practical communication appropriate to the applicant's standing; they do not specify a CEFR level. Evidence: conditional.

Source location: Act section 8(1)(e); regulations 9(3), printed pages 4-5. ## 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. Evidence: conditional.

Source location: Sections 8(5), 9(5)(a), 11(3)(b),(4)-(6), and Second Schedule, printed pages 12-16 and 23. ## 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. Evidence: conditional.

Source location: Act sections 8(1),(5) and 13; regulations 8 and 16, forms E1/E2/K; current AGC statute register. ## 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. ## Explore this passport - [Passport rank and travel access](https://multipassrank.com/passport/brunei) - [Tax residence & income](https://multipassrank.com/passport/brunei/taxes) - [Country-profile JSON, including sources and scoped requirements](https://multipassrank.com/api/v1/country-profiles/BN) - [Multiple-citizenship policy guide](https://multipassrank.com/dual-citizenship-countries) [Canonical page](https://multipassrank.com/passport/brunei/citizenship)
