Hello, I have been living in Singapore for the past 15 years and hold a PR Status (Filipino Nationality). Currently waiting for A' Level results and planning to stay in SG for uni. However last year, I applied for a Singaporean Citizenship around June and by September, received a notice of rejection that said "We have considered your application carefully but regret to inform you that it has been rejected."
My parents suggested applying once again as a family after a few months when I am allowed to reapply again but any suggestions on why it was rejected? My friends suggested that it might due to my age seeing as I am only turning 19 this year and applied last year for the citizenship on my own. Would applying as a family make any difference? I have been living in Singapore since I was very young and resonate to the Singaporean culture strongly since this is where I was brought up and I have no plans of returning to Philippines in the future. My parents' income is not too bad I think it's around $15k (combined) and my sister is also working here.
Any suggestions on what might have went wrong in the first place? I know SG Citizenship approval rates have decreased around 50% recently and that Filipinos are classified under "others" in ethnicity and have a low percentage of around 2% acceptance rate. Also if anybody has gone through the same experience before, would you mind providing some advice? Thank you.
