In case you plan to rush to acquire a Singaporean Passport, keep in mind it is not going to be easy. According to Wikipedia
Singaporean nationality law is derived from the Constitution of Singapore and is based on jus sanguinis and a modified form of jus soli. There are three ways of acquiring Singaporean citizenship: by birth, by descent, or by registration. Citizenship by naturalisation is no longer granted.
A person can apply for registration as a Singaporean citizen if he or she has been a Permanent Resident for at least two years and is gainfully employed or married to a Singaporean citizen.
