Apply for Parents end of 2007.
Received response in end of Nov 2011
Submitted papers back around Dec 15, 2011.
In Jan, 2012 received confirmation for permanent residence received.
Got 2nd email end of the Jan, 2012 that sponsorship application needs additional documents. They asked for 2007 "C Printout for 2007", T4/T5, other income, T1 General. They gave 60 days to response.
Anyone else got this?
Additional documents submitted in March 2012.
But as all suggested, whoever submitted by Dec 15, got response of permanent residence received.
Another way to confirm is by looking online in your case & if you see additional line
Sponsorship Application Status
Permanent Residence Application Status
and see double line.
if they ask for additional documents this year... it will be several months or a year to get some response due to volume they got so far.
