I was born in Canada, mom holds Thai citizenship and dad holds Singaporean citizenship. I moved from Canada to Singapore at the age of 6. When I moved to Singapore, my parents applied for Singaporean citizenship for myself and I got a certificate of Singapore citizenship. I ended up studying from Primary 1 till Secondary 2 before moving back to Canada at the wish of my mother.
At the age of 21, I received a mail from Singapore to perform the Oath of Renunciation, Allegiance and Loyalty in order to retain my Singaporean citizenship, which I did not do and thus lost my citizenship.
My mom didn't apply for an exit permit or notify CMBP of her intentions to renounce my citizenship. Is it likely that I won't be able to visit Singapore?
