He became a Singaporean at the age of 17. Does he need to do military service?

According to Singapore's Conscription Law, all Singapore citizens and second-generation permanent residents aged 16.5 and above must register for national military service (ns). Once you reach 18, you need to be drafted into the army and perform full-time national service (NSF) for two years. After the full-time national service expires, they must also participate in active service for 40 days every year until they reach the age of 50 (officers) or 40 (other ranks). For example, male permanent residents who have obtained permanent resident status because of their parents' guarantee must also perform national service.

In other words, all male citizens or permanent residents in Singapore have the obligation to perform military service, even if they are immigrants aged 17. Only when this person is:

Applicants who have become the first generation immigrants under the "permanent resident plan for professionals, technicians and skilled workers" or "permanent resident plan for investors"

Disabled persons with physical examination reports from relevant medical institutions.

Homosexual

Rights:

During the service period, active servicemen can receive a minimum salary of S $420 per month. The universities where active servicemen apply before serving will keep their student status for active servicemen, and they can continue their studies after serving in the military.

Penalties for non-performance of obligations:

Those who evade military service will be tried by a military court and sentenced to up to three years' imprisonment or a fine of up to S $5,000. For immigrants, failure to perform military service obligations will lose their permanent resident status.

Precautions:

Men who have the obligation to perform military service and are over 13 years old need to obtain an exit permit when they need to travel abroad for more than 3 months.
