I am a Singapore PR and I wish to change my name with a Deed Poll, what are ICA’s policies?

We understand that Singapore permanent residents with a change of name must first update the name on their current passport and provide a copy of the passport bearing their new name as a supporting document to change the name on the Singapore IC. For more enquiries, please check with ICA.
