Yes, if he holds Singapore permanent residency or citizenship. National Service (NS) is approximately two years of full-time service upon reaching the required age, followed by reservist obligations thereafter. This is a factor that many families are not adequately informed about.

However, public transportation is excellent and affordable, and dining at hawker centres is very reasonably priced.

Absolutely. English is the language of administration, education, and business — a major advantage for Vietnamese nationals compared to those from Japan, Korea, or mainland China. Singapore has four official languages, but English serves as the common language.

The legal system is very strict. Violations that are considered minor elsewhere — littering, importing chewing gum, traffic violations — carry heavy penalties. Offences related to drugs carry extremely severe punishments. You and your family must fully understand this before relocating.
