Dual Citizenship Rules in Singapore
Dual citizenship means holding the citizenship of two countries at the same time; Singapore does not allow adult citizens to retain another citizenship indefinitely.
Key facts
-
Adult applicants approved in principle for Singapore citizenship must complete applicable foreign-citizenship renunciation steps before registration when ICA instructs them to do so.
-
PR status does not itself require a person to renounce foreign citizenship.
-
A child who holds Singapore citizenship and another nationality may face citizenship-retention and foreign-nationality renunciation requirements on reaching adulthood.
-
National Service obligations can affect whether a male citizen's renunciation application is accepted.
-
Foreign-country renunciation rules vary, so applicants should confirm requirements with the relevant foreign authority.
