I have another question. Now everybody must submit bio-metrics... should we wait for the request (this adds more time to the process) or, can we pay the fee, get the bio-metrics and upload as additional documents?
Eduardo, you don't need it If you have the application in progress.
About your passport, there should be something in the website, I believe it is a complex, but fairly common situation.
Please double check, but I think it is logical to get the new passport in time for the PPR, and as soon as possible as permits are only issued for the duration of the passports, and they are not void if you get a new one, and in the meantime, you must plan ahead and apply for new permits to stay in Canada legally. Just updated CIC of your new document when you have it.
Now for the worst part, let's hope your new passport comes before they request it, or that the PPR comes soon, and you can explain the situation showing proof that you requested.
If they are not issuing passports and that is a stunt they are doing to pull people back to Venezuela, you better save proof that you requested it, and don't go back to Venezuela, because you may never come back, or at least for the next 3 years.
BTW, I found this, last answer in the thread has what you need (inside the quote box).
