Citizenship Law 2

A person is eligible to apply to be a citizen by registration as follows:

(a) He is above 18, born in Brunei and has within the period of 15 years immediately preceding the date of his application for registration resided in this country for periods amounting in the aggregate to not less than 12 years; and has resided here throughout the 2 years immediately preceding the date of his application. He will also need to pass an examination by a Language Board on his proficiency of the Malay language.

(b) She is a non citizen woman married to a citizen (no language proficiency requirement)

(c) A child under 18 years if a parent is a citizen. "Parent" here includes his mother or an adopted parent.

In any other case a person may apply for citizenship by naturalisation (in Malay penuangan) if he has within the period of 25 years immediately preceding the date of his application resided in Brunei for periods amounting in the aggregate to not less than 20 years and has resided here throughout the 2 years immediately preceding the date of his application. The language proficiency requirement also applies. Incidentally, unless this requirement is waived by His Majesty, the period does not include a period during which a person is allowed to remain temporarily here under the authority of any Immigration pass or permit issued. For example, in the case of a contract officer who has been in this country for the purpose of employment , the employment period is excluded.
