Yay! We have movement in Ottawa. We received an email today from the VO requesting my husband's CSQ (which is odd, since the Québec immigration ministry should have forwarded it automatically); more evidence of my intention to return to Canada (as I, the sponsor, am currently living in the UK) and confirmation of my husband's postal address.
We are visiting Québec next week to look for an apartment, so we'll document our search and (hopefully) our lease agreement. I'm hoping that will be sufficient proof of my intention to return, as I don't have a job offer or a plane ticket yet...
I'm a bit bummed that this might delay our application further (they gave us 45 days to comply), but relieved to finally see some movement.
