This note from CIC Singapore website caught my attention since my return envelope is not paid although UPS specified that I will be paying the charges. I'm worried that they send them through registered mail again
How will my original passport(s) be returned?
1.
Registered Mail: If you enclosed a self-addressed envelope and requested mail service, your passport(s) will be returned to you by registered mail
2.

if you provided a courier envelope or waybill and there is no evidence that you have already paid for return courier service, your passport(s) will be returned by registered mail
