I think you are missing the point. The person with dual citizenship is better of than one with a single citizenship if all things remain equal. It simple arithmetic of having more options and opportunities for yourself and your kids.
It matters little if the law places an obligation and one gives up the citizenship without following the rules. The end effect is your male offsprings can never enter Singapore while parents having erred still can. A certain disservice to one's son.
Many have made the right decision to withdraw their CPF because of it low returns and unfortunately that calls for renoucing the citizenship. I am sure if it was not requirement they would have held on to it. So if CPF is not a factor and if one follows the rules set out to seek exemption from NS, why screw yourself and your kids.
I have been asked to help on so many occasions when their kids are refused employment pass or refused entry that I know that it quite an issue.
Pls read the Defence Ministar's Teo statement (if should be implemented by now).. it stated clearly if the offspring has not served the NS, the Authority has the right to withhold 50% or more as a form of penalty.
Why shld we subject to the harsh treatment if we worked hard for 'our' funds ? served our term in NS.. This is our blood money hor. CPF is our retirement fund and should not be held as a ransom for another issue ie offspring or other mother's son issues..
As long as you have "assets" in SG, you are bound by their barbaric rule.. Oh, this includes freezing your assets for defamation or alleged IRAS invasion or failure to obtain permit etc..
Minor option comes with huge liabilities.. (yet others be paid for millions) after a careful consideration it is good to let go.. You can only comment on my case if you have a 'son'.. due for NS.. otherwise, it is rubbish..
I dont mean to be rude..
-for the "growth" (CPF) point of view, it makes sense to renounce...
-for "liabilities" point of view, renouncing is inevitable...
-for "visiting and staying long term" point of view, we have 2nd HOME M'sia scheme as PR, giving us multiple entry..
-for "Option & Opportunity", we hv Hong Kong, Taiwan, China, US UK, Europe.. I'm sure the salary package is comparable or higher than SG.
-Lastly, for "family bond and happiness", Errrr..... I shall say no more..
