Thanks to all replies.
I
would like to know the ‘age 11’ rule is from where? I could not
find it in the official web. If my son only can choose one
passport, he would prefer to have Aussie one, since his education
and future career will be here. However, he does like Singapore and
wish can go to Singapore as same as other people. He does not mind
to serve NS if he can keep his Singapore passport or even if he can
convert to PR. If he will anyway be “blaklisted” and can not go to
Singapore in the future, then what is the point to serve NS? I
really don’t understand the logic behind this.
One more question is: even he is overseas now, does he still
have to apply for ‘exit permit’?
Thanks.
The "age 11 rule" applies if you are in Singapore and are going
to leave Singapore. Within the territory of Singapore, you may not
renounce Singapore citizenship beyond the age of 11.
If you are overseas, how can you expect Singapore jurisdiction
to apply? Simply go to the Singapore embassy nearest you, fill up a
form and get rid of it once and for all. Many have done so and will
continue to do so, it takes mere minutes. This applies at any
age.
Your main concern is having citizenship or right of residence in
Australia or your chosen country of residence, otherwise you will
be stateless.
