Non-Citizens
Second Generation Permanent Residents are required to go through compulsory full-time national service as well as reservist duties after they have completed their full-time national service and turns operationally-ready.
After completing full-time national service, they are eligible to apply for Singapore citizenship. However, citizenship is not guaranteed for all applicants, as there are certain criteria that must be met such as educational qualifications and income qualifications. From 2006 to 2010, about 2% of 3,000 Second Generation Permanent Residents who completed full-time national service and applied for Singapore citizenship were rejected.
If the person does not hold Singapore citizenship but still holds Singapore permanent residency, he is still required to serve the service requirement, i.e. reservist duties after he turns operationally-ready.
Singapore Permanent Residents who served national service but did not acquire Singapore citizenship will be treated equally to those permanent residents without service obligation; they would not have access to the privileges granted to Singapore citizens.
