You can choose what citizenship you need till a certain age.
If you choose not to retain Singapore citizenship then it lapses.
You might be eligible for NS if you decide to return to SG I guess.
This is purely based on my understanding, one of the vetrans should be able to build on this.
Incorrect.
1. Under the SG consitution the right of dual citizenship of a minor by parent of Singapore is allowed if born overseas.
2. The minor is allowed to hold dual citizenship at the age of 21. Or for male minor 18 pre NS enlistment
3. The SG citizenship overwrites any other citizenship similar to US. Hence if you are over 21, if you have dual foreign citizenship you have to forego your foreign one. SG does not recognise dual citizenship after 21. Unless you renounce your SG citizenship then you can have your foreign one
4. At 21, you must state your intention on which citizenship you want to hold. Since the OP did not get any exit permit after 13 till 21, by default his SG Citizenship is void. I believe the passport has expired too by then. The OP did not return to SG over that period, ICA by default renounce his SG citizenship as he did not gain any socio economic benefits from SG. However as the OP has said "Checked with MISDEF saying that my citizenship was ceased already at my aged of 22 since i never returned for NS reporting." , he has committed an offense as no EP was applied when he turn 13 and a second offence of not reporting for NS
5. Since he is at the age bracket of 30 to 40, he will not be eligble for NS active duties thus making his return pointless unless to pay for his offense committed.
Having said all that, I doubt he is allowed to work here.
OP, please contact ICA i.e Citizen Advise Bureau, check if your name is still inside their record . If not you can try your luck to work here.
Do not identify yourself as the name search .
If yes, I do not think you can even visit SG
Sorry this is how it works
