Here is the situation.
1) My parents came to Singapore and gained PR status and applied one for me too.
2) My parents renounced their PR, along with mine and left in 2002 to emigrate to Canada. I was 13 years old.
3) Since then, we moved to the UK and gained british nationality.
4) I recently got a job offer from a french company in Singapore, who are applying for my Employment Pass, which will take up to 2 months. I am now 23 years old.
Will there be any employment pass issues in returning ex-PRs who did not serve NS (as my parents renounced my PR status when I was at a young age)?
Since you asked 3 times, here is your 3rd reply
Yes, the issue is it will probably be denied. Unless your salary is enough to qualify you for a P1 Employment Pass *and* it is a highly niche role, I would bet a paycheck you get rejected.
Your family is very obviously taking advantage of every system they can, and leaving as soon as they can for greener pastures. MOM and ICA work together to try and keep such types out, and they're quite good at catching them.
Also, based on your family's behaviour, I'll make the guess there is a very good chance you're Indian. Indians are over the racial quota, and the gov is trying to fix that quota. You'd have a hard time without everything else against you.
