To echo everyone's anxiety
I wanna share my case as well. My passport was delivered to CPP on 10 April and I haven't received it back. I sent 2 emails but got no response but the auto-replies. I am from Vietnam but working in Singapore and my job requires me to travel abroad 2 times per month. I desperately need my passport now. I already missed 2 trips. The worst is not knowing when the passport is returned so no planning can be made. It's a terrible situation!
My case is even more complicated. I asked a friend in Canada to send me an International XpressPost to Singapore. I enclosed it together with my passport. I hope they will use the envelope (the delivery address is not in Canada) when they return my passport. The tracker hasn't been activated yet.
I think those who do not need a passport for travelling don't need to worry. The passports will be returned to us sooner or later. We have been waiting for at least a year for PR application to be complete. Few more weeks won't be a problem.
For me, I am going to contact Vietnam embassy for a temporary passport so I can travel soonest. I don't know if it works, but I hate being strained.
