Do male immigrants have to perform military service?

First-generation immigrants do not need to perform military service, but if your son also immigrated to Singapore because you are a permanent resident, he must perform military service.

Upon reaching 16½ years of age, they need to enlist for National Service (NS) and will serve two years of full-time NS at 18 years of age. Thereafter, they will serve intermittent duty as a citizen-soldier for a cycle of 10 years.
