MilesAway said:You're quoting information about Express Entry, which has different requirements.
Some countries do require a document from CIC to get a police check, but since you haven't said what country you are from, I cannot give you any more details.
You should submit police certificates upfront for Family Class.
MilesAway said:For IMM0008DEP:
Additional Dependants/Declaration (IMM 0008DEP) if applicable.
If you have more than five (5) family members, you must complete the Additional Dependants/Declaration (IMM 0008DEP) form for each additional family member in order to include everyone in your application.
Do you have too many children to list on IMM0008? If yes, then you need to fill out IMM0008DEP. Otherwise, no.
If you are from the UK or Hong Kong, I would strongly recommend you apply outland. The processing will be much faster.
As for the Hong Kong police certificate, I would suggest you ask in the Hong Kong VO thread. http://www.canadavisa.com/canada-immigration-discussion-board/hong-kong-timeline-t82193.2385.html
I don't have any experience applying for a certificate from there, although it seems that you can send in the application for it without a request letter.
MilesAway said:You can apply outland while in Canada. The inland guide even says so. You just need to extend your status. You can do that online. CIC recommends applying to extend your status 1 month prior to expiring.
MilesAway said:You fill out the forms for outland, follow the guides, and send it in to the Outland address. It's quite simple. Everything is mailed to Mississauga first, then forwarded to the VO for your home country.
You will need to apply to extend your stay, which can be done online.
People apply inland because they don't read the guides and realize that they can still apply outland. Others need visas and are afraid they won't be able to renew them, while others get lured in by the OWP. A lot of people who apply inland quickly learn to regret their decision when they are waiting 2+ years later, while people who applied 14 months after them have already landed.
Letters from family are not required (but check your guide, just to be sure), but I included some as proof that our relationship is genuine. You need to include whatever evidence you have to show that you are in a genuine relationship.
I'm not certain about the financial side of things. I've been outside of Canada for several years, so I didn't have any CRA documents to send in.
MilesAway said:The second link is the correct one. It should "Family Class", NOT "In Canada Class".
Many people have had their stays extended without issue. As for an interview, is there a particular reason you are worried about being called for an interview?
