National Service
Under the Enlistment Act 1970, all male Singapore citizens and permanent residents, unless exempted, are required to serve National Service (NS). They are required to register for NS upon reaching 16 and a half years old, and will be scheduled for enlistment into full-time NS at the earliest opportunity upon reaching 18 years old.
Following the completion of full-time NS, they will become Operationally Ready National Servicemen (NSmen). An NSman's obligation will end at the age of 50 years (for officers) or 40 years (for other ranks).
Renouncing or losing one's PR status without serving or completing full-time NS will have a serious adverse impact on applications to work or study in Singapore, or for any long-term immigration facilities in Singapore, whether now or in the future. Renouncing or losing one's PR status without serving or completing full-time NS will also adversely affect your family members' applcaition for long-term immigration facilities, their ability to sponsor such facilities, their renewal of Re-Entry Permits, or their applications for Singapore citizenship.
