Purpose and preparation
The landing separates public/non-public officers. Prepare signature, support letter, professional membership/reasons or overseas business registration as relevant, plus a valid Singapore passport.
Choose the correct operation
Applicants use their own Singpass. Submitted particulars including passport number cannot be changed, so obtain the correct passport first. Other nationalities/PRs apply through the home economy.
