How to update my Singapore PR application for subsequent changes after filing?

Suppose there are significant changes in your circumstances after filing a PR application. In that case, you can notify ICA about this by writing to them at ICA_PR@ica.gov.sg or contact them physically at their offices at Immigration & Checkpoints Authority ICA Building 10 Kallang Road Singapore 208718.

Make sure to include scanned copies of all relevant documents along with your application.
