hope for the best said:Well, if you want to say that then everything is out of your control .... but for FBI PCC it takes FBI more than 4 months to issue one and that is something definitely out of applicants' control and there is nothing we can do about it. But the letter from your employer is not something really out of your control unless you really did somethings to piss off your employer that much and they won't issue you one. Even if your previous company does not exist anymore then if you are able to provide evidences to show CIC then I am sure as long as your evidence is legit then CIC will treat it as a special case. However at the end of the day it really depends on your visa officer and how legit your evidence is.
The time has nothing to do with it. Being unable to get a document and being unwilling to decline an ITA and wait on an outstanding document that you can get regardless of the time are too different things. If you cannot get your documents together in 60 days do not enter the pool. Its that simple. That is CICs operating principle as is evidenced by the number of applications being rejected. Having to ask for documents extends the processing time. They are trying to avoid that.
