Hey there just going thru some old posts and thought I would post this for some of the new people....it kind of gives an idea of what happens to you file when you apply:
Most of the 82 days is basically a waiting period, the actual approval of a sponsor takes 1-3 days in most average cases. Remember, this is simply a case of verifying some financial and legal information, which I'm sure CIC has access to for their purposes. Also, this is the office that handles ALL sponsorship cases outside Canada, they handle literally thousands of packages per day, hence the waiting. Once the sponsor is approved, after about 2-3 days your eCAS goes active.
Once that is done, your package moves to CPP-Ottawa for transfer by diplomatic mail. Depending on where it's going, that takes about 10-14 days and then it arrives at KG. KG will then upload the files on their system, again this might take about 2-3 weeks after your file leaves Canada. In our case, we were approved on May 9, and out file was transferred to KG by May 19, and by May 25 the electronic file had been created. The creation of your file in KG will trigger another eCAS update, which will show the applicant's details if they bother to enter them (such as address).
After that, in general, you hear nothing from KG and your eCAS will likely go static. That is why I highly recommend the eCAS tracker, as it saves you the trouble of checking it obsessively, because really, nothing much happens on it and sometimes it can be inaccurate, especially when they upgrade it.
After some months you get an "In process" update, which means KG is ready to do something for you. Look out for either a re-do request for PCC and meds, or a PPR to submit your passport for visa insertion if these are still current (done less than a year ago). If you are cutting it close, they might also ask you for a flight itinerary which has you leaving Jamaica by a specific date. They might also ask to see your original marriage and birth certificates (these will be returned with the passport).
And, that, in a nutshell, is the process. For KG, it can take between 6 months (their current 20% estimate) and 15 months (their current 80% estimate) or it can take even longer (for the 20% that require more than average time). Whatever it takes will depend on your relationship circumstances, on the background of the applicant and several other factors, not all of which will be understood by us because we aren't privy to all the processing that takes place on these applications.
