well a PHAC means to issue a visa immediately as there is a grave situation. It was my friend who was in the hospital and is scheduled for surgery in a few weeks. It is appalling how they work on some files. It is what it isExpediting application doesn't mean a positive outcome and again it may be difficult to say why his/her application was refused without knowing other background details. And I agree, you need to put a good application and be lucky as well, have seen visa officers rejecting files for silly reasons.
