不过看ICA上说的意思好像要是不服兵役，以后就不能回新加坡了。。
Male children who are granted PR status under their parents' sponsorship are liable for NS under the Enlistment Act.
......
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.
所以想问问看，不知道理解错了没
