Hmm. Where to start.
Since you are already married ("family class"), your dh will get priority. I believe it is also faster to start the process from abroad, rather than in Canada.
Have you looked at the application forms online? You can download a pdf. The questions aren't that difficult, just really long and requiring a lot of detail. It actually took us longer to complete the application (about 6 months),than it took the embassy to approve it (about 3 months!)
When I say 6 months, I don't mean we were working on it all the time..! Most of the questions were about our relationship, how we met etc. I suppose to make sure we hadn't just gotten married to move to Canada! It took us awhile to remember/look up important dates, locate and copy old photos, write essay type questions, dh to do the medical, etc. It's worth doing it right, because if you forget some small thing, like put in the wrong number of photos, or don't sign it properly or whatever, they return the whole thing to you and you have to start over!
Yes, we live in Nova Scotia now, it's great!
It shouldn't matter if you're working or not, you're a citizen and the idea is you are moving back home to be with your family.
Good luck, feel free to ask me more...
