Can anyone’s citizenship be revoked by the Government? To understand that, one needs to know how a Singapore citizenship is acquired. Our Constitution provides four means:
By birth (being born here)
By descent (born outside of Singapore, but parents are Singaporeans)
by registration (any person resident in Singapore over 21 years old can apply by registration)
by naturalisation (any person residing in Singapore for more than 10 years
Only persons whom are citizens by registration or naturalisation face many scenarios where they are deprived of citizenship. Reasons for doing so include:
Fraud, when applying for citizenship,
Citizenship granted by mistake,
Disloyal or disaffected towards Singapore,
By serving a foreign government or political office where an oath to them is taken,
Naturalised citizens can have citizenship revoked if you have been staying abroad for over 5 years,
Women who have received citizenship by registration can have it revoked if authorities are convinced marriage had been dissolved,
Engaged in activities prejudicial to: the security of Singapore, the maintenance of public order, the maintenance of essential services or involved in criminal activities prejudicial to the internet of public safety, peace or good order.
Singaporeans by birth appear to be protected from deprivation of citizenship, except in cases of treason or acquisition of citizenship of another country. There is no dual citizenship for Singapore citizens, does not matter whether or not you are male or female. There is popular misconception that Singaporean women can hold dual citizenship.
It is normal for countries to revoke citizenship. The United Kingdom has provisions for stripping citizenship and the United States had revoked citizenship for reasons from anything between lying and bigamy to having Nazi connections.
