1) Renunciation
A person can voluntarily renounce their Malaysian citizenship by submitting a written declaration to the Malaysian government. The declaration must be made in the presence of a Malaysian consular officer or other authorised official.
2) Deprivation
The Malaysian government can deprive a person of their citizenship if they are convicted of certain serious offences, such as treason, sedition, or terrorism. The government can also deprive a person of their citizenship if they are deemed to have "failed in their duty as a citizen".
3) Loss of Nationality Through Expatriation
Malaysian citizenship is lost if a person voluntarily acquires citizenship of another country unless the other country is not recognized as a country, or if a person is declared a citizen or national of a foreign country by a competent authority of that country and fails to make a declaration to retain Malaysian citizenship within one year of the declaration.
4) Termination
The Malaysian government can terminate the citizenship of a person who has been absent from Malaysia for a continuous period of not less than five years, unless they are in the service of the government or any international organization of which Malaysia is a member.
5) Acquisition of Foreign Nationality
A Malaysian citizen who voluntarily acquires the citizenship of another country loses Malaysian citizenship unless, within one year of the acquisition of foreign citizenship, the person makes a written declaration to the Minister to preserve Malaysian citizenship. This option is not available if the other country is not recognized by Malaysia.
