A citizen of Singapore can only renounce his/her Singapore citizenship if he/she:


  • Is aged 21 and above;
  • Is of sound mind; and
  • Has acquired the citizenship of another country.


The Government may reject the renunciation of Singapore citizenship by a male citizen if he has enjoyed citizenship privileges, including possession or use of the Singapore passport, and has outstanding National Service (NS) obligations.


All Singapore Citizenship Renunciation applications must be submitted via the Immigration and Checkpoints Authority (ICA) online application portal. The link to the online application portal and detailed information regarding the process and required documents can be found at ICA’s website www.ica.gov.sg/enter-depart/for-singapore-citizens/renunciation.
