Hi Mapleson,
I've seen you post these stats a few times now, but was curious what the source of this data is? personally, I've had so many different stats thrown my way throughout this process, at times it's hard to differentiate between conjecture and reality (being emotionally compromised in this makes it even harder).
In my case, I've had the luck of knowing 3 other individuals who all submitted their applications within a 3 week span of my own, so other than being able to compare notes and use them as a de facto support group, it's also allowed my to compare timelines and responses so far.
With the last of these applications having been confirmed as transferred and received by the VO in Havana in mid April, the only communication since has been 2 weeks ago, when one of my friends got an email requesting additional documentation.
Hence, this leads me to believe that something is actually happening there (contrary to apps just collecting dust on a shelf) and that other than the spouses getting the call, no news is good news, but still makes it difficult to estimate when that call might come.
it will be telling to know if all of us within my group will be called around the same time, as our circumstances differ significantly, or is this really a first come/first served process such as it was on the Mississauga end of the process.
