영주권 받고 군대안가도 됩니다, 다만 영주권갱신이 힘든 건 확실합니다. 참고로 위에 말레이 인도애들이 주로하는 포럼은 잘못된 정보들이 엄청 많으니 직접문의해보시는 게 낫겠죠.

<National Service Liability>

Under the Enlistment Act, all male Singapore Citizens and Permanent Residents, unless exempted, are liable to register for National Service (NS). Following the completion of full-time NS, they will be required to serve up to 40 days of Operationally Ready National Service (ORNS) per year for the duration of their ORNS training cycle till the age of 50 years (for officers) or 40 years (for other ranks).
 
Main applicants who are granted PR status under the Professionals/Technical Personnel and Skilled Workers (PTS) Scheme or the Investor Scheme are exempted from NS. Male children who are granted PR status under their parents' sponsorship are liable for NS under the Enlistment Act. They are required to register for NS upon reaching 16½ years old and will be scheduled for enlistment at the earliest opportunity upon reaching 18 years old. If they are pursuing full-time studies, deferment from full-time NS may be granted only if they meet the deferment conditions stipulated by the Ministry of Defence which can be found at www.ns.sg. All NS-liable males aged 13 years old and above, are required to obtain an Exit Permit (EP) when travelling overseas for 3 months or more.
 
NS-liable PRs are expected to serve NS. Renouncing or losing one's PR status without serving or completing full-time NS would have an adverse impact on any immediate or future applications to work or study in Singapore, or for Singapore citizenship or PR status.
 
Males who are granted Singapore PR, and who were previously Singapore Citizens or Singapore Permanent Residents, are liable to be called up for NS regardless of the type of PR status they have been granted.

남자라도 본인이 PR Main applicant 냐 아니냐에 따라 다른 것 같은데요.

저기는 당연히 미성년자 남자 아이를 말하는 거죠, 신청한 아빠가 싱가폴 군대 갈리가 없잖아요 ㅋ Main applicants who are granted PR status under the Professionals/Technical Personnel and Skilled Workers (PTS) Scheme or the Investor Scheme are exempted from NS.
